Alex Guerrero: A doctor’s take on Tom Brady’s body coach

I have a confession to make: I own a TB12 hat. Not only do I own one, I really really love the thing. So, it’s with mixed emotions that I write this.

Alex Guerrero is half of TB12. He’s more than just Tom Brady’s business partner, though. He is the quarterback’s body coach, fitness guru, nutritionist, masseuse, spiritual advisor and close friend. While much has been written about Guerrero, he remains a mysterious character – always present, yet one step outside of the spotlight. He’s been publicly called both a miracle worker and a “glorified snake oil salesman.” He has been lauded by professional sports stars like Willie McGinest and is being watched closely by the Federal Trade Commission. Alex Guerrero, it seems, is an enigma.

Mike Chambers authored an article in Men’s Journal this week in which he described a few visits with Guerrero at the TB12 facility in Foxborough. It was a very personal piece – Chambers had fractured his heel bone in a rock-climbing fall and came to the body coach for treatment during his recovery.

What truly infuriated me about the article was that Chambers pitted Alex Guerrero against the surgeon who had reassembled the shattered pieces of his heel, going as far as to say that it was “as if [he’d] had an affair.” Actually, maybe it was Guerrero who set that tone in their very first session:

“Is it safe?” I ask Guerrero, 51, whom I met through a mutual friend. “I’m not actually supposed to be bearing any weight.”

He pauses, giving me his undivided attention. “It’s completely understandable that your surgeon’s number one goal is to protect his surgery site,” he explains. “He doesn’t care if you ever run again. He doesn’t care if you want to climb Mount Everest. But here’s the thing about rest: It makes you feel better, but it doesn’t make you get better.”

When a calcaneus shatters it is like a piece of shrapnel exploding. Bone fragments splinter in all directions, the fat and connective tissues swell so tremendously that it is often impossible to suture the skin around it. The risk of infection is high, the risk of the bone not healing correctly is very real. These are facts that have been studied and published in medical journals after being carefully scrutinized by doctors in the field. I’m not a surgeon, but I am a sports medicine doctor who cares for thousands of athletes every year. Yes – I said “cares for.” I care for each and every one of my patients. Even the difficult ones who don’t listen to what I recommend. Even the ones who seem to doubt what I’m telling them. In fact, I spend MORE time with those patients because I care so much. I care that my 67 year-old competitive sprinter still wants to sprint despite terrible hip arthritis. I care that my 10 year-old ballerina is dying to go en pointe but her feet aren’t ready yet. I lose sleep over my HS senior who wants so badly to play in his Thanksgiving football game but might not be ready.

Here’s the thing – Alex Guerrero doesn’t know if it’s safe to have Chambers bear even 10% of his body weight on the treadmill, because Guerrero functions in a different world than doctors. He doesn’t have to prove his therapies work, or even that they are safe. The thing about functioning in a space like that is that it’s very easy to become cavalier. If you don’t follow the patients with calcaneus fractures who stop coming to your out-of-pocket full-service gym, then you may not know if some of them go on to develop non-unions of their fracture or breakdown of their skin and soft tissues from walking on a treadmill too soon. So because all you see are the successful cases, weight-bearing at 3 weeks is safe and, even further, necessary. Maybe Guerrero has never had a case of a client (I call them patients) who took very high doses of calcium and vitamin D go on to develop painful kidney stones. Yes, flushing the kidneys with water can help prevent this but even in patients with active fractures there is no evidence that supratherapeutic doses of calcium are beneficial and we know they can cause harm.

And then there’s the whole alkaline diet situation. The assumption is that an acidic diet is inflammatory to the body. Tom Brady reportedly follows an 80-20 diet (roughly 80% alkaline, 20% acidic) to keep his body alkaline. Know who else is closely monitoring Tom Brady’s blood pH? His kidneys. If you have at least one well-functioning kidney then you don’t need a $200 manual to keep your blood pH stable. In fact, no matter how hard you try, you can’t trick those little bean-shaped buggers. Your pH will not budge.

While I’m at it, raise your hand if you paid $200 for a pair of recovery pajamas. My God, people. Seriously? I’m sorry – I can’t judge. I have an elliptical machine I’ve used twice that now serves as a drying rack for wet clothes. At lease you have some comfy pajamas.

The biggest problem I have with Alex Guerrero isn’t just that he has been banned from falsely calling himself a doctor. It’s not that he was fined by the FTC for marketing a miracle cancer-curing supplement he falsely claimed he studied in 200 terminally ill patients. It’s not the concussion water he sold that Brady still claims to be effective in improving brain healing and protection. No, the biggest problem I have with Alex Guerrero is that, while he and Tom Brady seem to really believe in their methods and outcomes, they don’t study and share them. They continue to profit from non-proven treatments, supplements, and other therapies and none of those profits seem to be invested in studying their efficacy.

Despite everything that I have written to this point, I truly believe there is a lot of good going on at TB12. In fact, when I read that Chambers had seen Rob Gronkowski getting work done at the facility I let out a very loud “Thank God.” Gronk is a tight, muscle-bound athlete with chronic back issues who could benefit from the kinds of treatments Guerrero offers. There is a lot to be said for the importance of muscle and soft tissue pliability, which is something that the body coach seems to know quite a bit about. Functional training – using body weight and resistance bands to ensure proper balance of strength – is widely used in athletic performance training. Neuromuscular training is also critical – putting the body through repetitive movements that the athlete has to perform on the field trains not only the muscles but the nerves and is shown to be protective. An excellent example of neuromuscular training is ACL prevention therapy, where athletes train their bodies to pivot and land in ways to minimize risk of ACL rupture.

In fact, it’s not just what happens in the gym at TB12 that sound promising. While Tom Brady’s diet is a bit extreme, there are clearly nutritional benefits to eating less processed foods and less sugar. Drinking water is great for your body. Meditation, accupuncture, massage – these are all tools I use in my practice. (That was a lie, I don’t really meditate. I don’t ask my patients to meditate. I do have a really cool Buddha tank top that makes me both wish I meditated and look like I just meditated 5 minutes ago though.)

Alex Guerrero has said that trainers and other medical professionals have called him a “quack.” It’s a shame to me that athletes feel like they have to chose between the body work that Guerrero offers and the medical care that doctors provide. It enrages me to know that Guerrero is telling clients that their doctors don’t care about them and that their post-op protocols are bogus and even harmful. It’s pretty clear that I don’t agree with everything that Guerrero and Brady are peddling. That’s okay, it’s not a reason to close the lines of communication and function only behind closed doors.

One thing is for sure – Alex Guerrero isn’t going anywhere. It’s early May and Jimmy Garropolo is still a Patriot. The death-watch for the greatest quarterback to ever play the game continues. Because Tom Brady is the face of Alex Guerrero’s methods, the body guru has found himself smack dab in the middle of a smoldering sports drama that he himself continues to perpetuate. That’s a lot of free press for a $50 per bag-of-nuts business. In my opinion, such high-profile therapy carries with it a significant amount of responsibility to potential consumers.

Alex Guerrero needs to put his money where his mouth is. He owes it to his clients to prove that what he is doing works. Look, not everything in medicine is black and white. In fact, we function in an area of grey a lot of the time. That being said, the best way to treat athletes (and non-athletes) is to strive to make the grey parts either more black or more white, to figure out what does harm and what does good. You can only achieve that if you either practice what is proven or study what is not. In 2015 Tom Brady said on 93.7 WEEI that educating athletes about the care he received from Alex Guerrero would be his “calling” after football. I really hope that he and Alex Guerrero will share and, more importantly, study their outcomes as much as they advertise their business going forward.

    1. Hi Chris. This is great point and I made a similar point when I was on CSNNE. The major difference, and what drove me to respond to the Men’s Journal article, is that we should all recognize and acknowledge the grey and try to make it black or white. I hope Alex responds to what I wrote – maybe he was unfairly quoted as saying that the author’s doctor “didn’t care” about him. Maybe there was a longer discussion about the risks of weightbearing that soon on a fractured calcaneus (a therapy that is currently not shown to be in the “grey” but rather pretty black and white). I was disappointed in the message that doctors and integrative/functional practitioners have to be at odds. Thanks for the feedback.

    As a licensed physical therapist and athletic trainer, Thank You!

    As a fellow medic I echo many of your comments. Some of the stuff he does is wonderful (all the pliability stuff), the other stuff not so much. I’m a urologist so the eye-opening thing for me was the diet. It is almost component for component the same diet we suggest for interstitial cystitis. There are some studies to back up low acidic diets reducing inflammation. Recent work has reduced the list of things to avoid. Most of them also trigger reflux. The diet works for 80% of IC patients. But is pretty brutal.


    1. That’s so interesting – never knew that! The IC low acidic diet is still based on the idea that the kidney will excrete any extra acid into the urine to maintain normal pH and if the urine is acidic it would theoretically irritate the lining of the bladder? Kind of the opposite of the whole acidic cranberry juice to acidify the urine to prevent UTIs (on a very basic level). Thanks, learned something new! I did do a PubMed search and couldn’t find any studies of alkaline diets and effect on body inflammation, however. If you know some I’d love to read them.


  5. Bathwater says:

    I better clarify. IC is a disease with breakdown in the nerve pathways from the bladder. The thinking (we don’t really know) is that there is cross talk from the gut to the bladder. Acidic foods trigger bowel inflammation which triggers bladder urge. Turns out it has nothing to do with bladder pH – the body is too good at buffering to really make a difference, and everything to do with inflammatory pathways.
    Here is a review – anything by Moldwin is good.
    Cranberry should never be given for an active UTI – it is like a hand grenade of inflammation – sometimes works to prevent UTI’s by blocking EColi pili attachments. I know it is all over the Web – at this point everybody regurgitates old medical information so much reality is drowned out. Sort of like cipro inhibiting bone regrowth (I think that has been disproven 😉 )


  6. Dr. Flynn,

    It is important to note that the TB12 rehab visit was just that…rehab AFTER the surgeon came to the rescue. My reading indicated that the patient chose to actively rehabilitate rather than sit, waste, and wait. His visits with Alex Guerrero were not a replacement for his medical care; they were in addition to it.

    Integrative care, the new term, is still a secret that some patients keep from their medical professionals. The more that articles are published, and epitomized athletes such as Tom Brady display their use of integrative care, the more that we all (physicians included) become informed. The more information, the less bias.

    It is time to publicize what the public has been seeking and acting on for a while. Putting down integrative care because you don’t know it or because there may not yet be published ample data reignites the old battle. Instead, find out what is going on there; rediscover the “art” that medicine once was. Treat patients as individuals and let’s stop being afraid to think and develop outside the box.

    It is unfair to accuse when you may not know that there is a foundation set up that helps offset the cost for others to afford this therapy; that’s the share part.

    It’s all about informing ourselves without drawing judgment; when we do that, we remain open to learning new techniques, the impetus to true sharing.

    1. While I appreciate the conversation, I’m not sure you understood my points, Dr. Foschi. Guerrero recommended against following the surgeon’s instructions which are based on good evidence without supplying a similar level of evidence to support his recommendations. I disagree that I “put down” integrative medicine and even employ some techniques in my practice. My issue with the article is that it took the story from the realm of “these treatments are not proven but I think they may help you and certainly won’t hurt you” to “I know your doctor told you not to do this but he doesn’t care if you climb Mt. Everest.” My major point is that integrative care and modern medicine do not need to be at odds with each other.

    Thanks for your post! I enjoyed reading it. And I really wish there existed a happy medium between the world of functional medicine and more traditional doctors. I thought I might just add another point of view as a patient or client.

    I work in animation and do a crazy amount of drawing in the computer and developed an overuse injury to my drawing arm. It forced me out of work (in a career that I love) for over three years. The reason that I was out so long was because the workers comp system would only authorize treatment from an orthopedic surgeon. And a limited number of visits with a physical therapist. The surgeon was unable to help me, as I was not a candidate for surgery, MRIs would only show some tendinitis, and medication did nothing to help. It felt as if the surgeon (who is one of the best in Beverly Hills) did not know any other way to help me. I felt like I had to diagnose myself. I went so far as to buy Travell’s textbook on upper extremity soft tissue injuries. My sister is also a physician and we would talk a lot about how medical schools spend very little time educating doctors on muscle tissue. I flew across the country to give TB12 a try and they really helped me where the traditional medical system failed, and it did feel like an us against them thing, but mostly because I had to defy the system to get help. Maybe the real problem here is the insurance companies who treat people like massage therapists, or places like TB12 as “not real medicine.” There’s no way I could get an insurance company to authorize treatment from a massage therapist. Or someone like Alex Guerrero even when their treatments are the only ones that help sometimes. It really would benefit EVERYONE if we could somehow get the two sides to unify. But from my point of view the insurance companies play a big role in pitting them against each other. What do you think?

    1. I agree wholeheartedly. I use massage therapists quite about in my practice, but I am finding as time goes by that patients can’t even afford traditional PT co-pays as some are $50 per visit! It’s really ridiculous and frustrating that insurance companies don’t see the value in keeping people active. That being said, the relationship between providers needs to be respectful. Unfortunately, at least in the article, Guerrero was not at all respectful of the physician who put the athlete’s heel back together. For a growing business with amazing potential, I think that’s a major issue.


  8. Excellent. Fun to read. As an athletic trainer, I will do my best to be respectful of every member of the health care system when I engage with a patient. Treating each patient as an N of 1 trial, using the best evidence-based medicine practices and my practice-based evidence to provide the highest level of care possible.
    What are your thoughts on the recent news of Bill Belichick reportly crubing Alex Guerrero privileges this season? Another fun discussion, could be who should be determining a patient’s care, a sports coach (Bill Belichick), a medical professional (either Alex Guerrero or the Patriots sport medicine staff) or the patient (Tom Brady)?


  9. Thank you for sharing this. I agree just because Alex Guerrero did some wanky things, it doesn’t discredit his body work.
    I do have to chime in and comment that he has to “prove that what he is doing works”. There is nothing better than walking living proof and that is Tom Brady. Tom Brady is the “lab rat” at the age of 40 one of the top quarterbacks in the NFL. If left to the “proven” trainers and body workers I think he would not be able to continue to play at the level he performs at. I understand that Alex Guerrero is a soft tissue specialist. Just want to share my story. In 2017 at the age of 47, i was training for my first Marathon on the Great wall of China. I had chronic hip issues and went to “proven” physical therapist for 2 months 2 times a week. A total of 16 times that was 16 hours of treatment and it did ABSOLUTELY NOTHING! I still had hip pain. Then after 4 more months of hip pain finally went to Ming Chew in NYC a soft tissue expert and PT and after literally a 20 min treatment fixed my hip pain. The treatment was painful but after being treated by him 2 more times i had no hip pain. In fact my bad hip felt better than my good hip. I ran the marathon on the great wall of china and also ran the NYC marathon later that year and still no hip issues. So to me that is proof and it holds a lot more validity than a controlled study. it would be interesting to see if you have multiple people with a similar injury and pit them against each other and see who can fix who quicker?


    1. I’m so glad that you’re doing better and were able to run. A marathon on the Great Wall sounds incredible. It would be great to see different methods of treatment compared to each other – what you’re suggesting is a great plan for a prospective study! Happy New Year and thanks for the comment and sharing your story.

    Thank you for speaking your truth & my thoughts. I appreciate your candor, fears, support, facts & humor. It was also nice to read an article that wasn’t written with malic or used slander to support their point – but facts.
    I believe there are many benefits with the theory behind TB12 & look forward to learning more. As you made clear, I also hope Alex does his (factual) research to support his theory.
    They do need to get a clear & conscise definition to this new exercise phrase “pliability” they are introducing to help others truely understand exactly what they are selling.
