Performance Physical Therapy for Active Adults Who Refuse to Train Around Pain
Using The NEX Performance System, we help active adults move stronger, perform better, and live pain-free through one-on-one physical therapy, sports rehab, and strength coaching built around your body, your goals, and your training.
Most physical therapy gets you out of pain. Then sends you back to the same body that got hurt in the first place.
The NEX Performance System finds why it keeps happening, and rebuilds the body that won't let it happen again.

What One-on-One Actually Looks Likes
At most outpatient clinics, your physical therapist sees 15-20 patients a day. Your hour often means 15 minutes of actual hands-on time, then theraband exercises while they move to the next room.
At Nex, there is no next room.
We see one patient at a time. Every session runs the full duration with our full attention. Between visits, your case doesn't sit in a file. It's actively considered, adjusted, and built upon. If something isn't working, the plan changes at the next session, not after.
That's not a premium add-on. That's just what care should look like.

Physical Therapy that worked after everything else didn't
Real five-star reviews from lifters, runners, and everyday athletes across North Miami Beach and Aventura, many of whom had already tried other physical therapy or chiropractic care before finding Nex.
I’ve dealt with lingering injuries, mobility limitations, and imbalances for a while. I’ve been to other PTs, who misdiagnosed the issue, treated the symptoms instead of the root cause, and gave very generic programs that never actually fixed anything. Working with Dr. Castro was completely different. He was able to identify issues that others missed and put together a program that actually made sense for my body and goals. He explains the why behind all the exercises, which made a huge difference.
I’ve spent so much money at other chiros, PT, massages, and sports therapists and hands down Dr. Felipe has been a wonderful experience. The level of care he put in the initial assessment was something I never experienced. My neck, lower back, and knee are in such a better place because of him. At first I thought it was more money than I wanted to spend, but the therapy has made my life so much easier.
Been to 2-3 physical therapists in the area, but while other locations gave me minimal guidance and felt impersonal, Dr. Castro was truly invested in my recovery. While other locations gave me an exercise routine and left me to my own devices, Dr. Castro examined my form and offered insight into the mechanics of how and why my body moves. It felt motivating to have a PT that was as invested in my success as I was.
Nex Performance and Rehab helped me with some back pain after many years of powerlifting. Whereas other facilities may just attempt to alleviate pain in the problem area, Felipe Castro dots all his i’s and crosses his t’s by assessing and executing treatment to other affected areas. 10/10 would recommend.
After trying different places (chiropractors, massage therapists, and on) I finally found what my shoulder needed. Nex made me realize I can go beyond my shoulder pain and can actually get back to enjoying training. It wasn’t about being dependent on Nex to get out of pain, but about getting on a system that made a lasting impact. Forever grateful!
Dr. Felipe Castro helped me tremendously with knee pain during my marathon training. He took the time to explain the cause of my pain and taught me how to prevent it, and allowed me to return to training as quickly and safely as possible. This is not like a typical clinic where doctors only spend a few minutes with you. His approach is truly one-on-one and individualized.
I’ve been working with Dr. Felipe for six weeks and I’m already showing massive signs of healing from my overly tight hips and a couple of injuries sustained from Jiu Jitsu. He’s developing a detailed plan with me, giving me organized instructions and taking detailed notes on where I’m at. An amazing out-of-network physical therapist.
I honestly thought my left knee would only get worse until it was time for a replacement. Felipe explained a different scenario. After six sessions, and knowing exactly what to do thanks to his follow-up emails complete with pictures of the exercises, I’m having much less pain now, and at 72. I feel like I have a handle on dealing with pain and, more importantly, how to compensate when it occurs.
I’ve been working with Felipe for the past few months on my shoulder rehabilitation, and the progress has been remarkable. From the very first session, his assessment was incredibly thorough and precise. He took the time to understand the root cause of the issue and designed a clear, structured plan. My shoulder strength, mobility, and overall performance have improved significantly.
Felipe is the absolute best in the game. I have dealt with many physical therapists in my life and he is without a doubt the most knowledgeable. I began with the intention of easing my back pain but ended up staying, because he not only eased the back pain but helped me build resilient strength. Couldn’t be happier!
I’m an avid runner who mixes in bodybuilding and calisthenics. Felipe’s expertise has guided me through these athletic transitions, equipping me with the right exercises for my training. When I do too much and sustain minor injuries, his personalized guidance and intimate knowledge of the body let him diagnose me quickly and accurately. I couldn’t recommend Felipe highly enough!
I had been in pain for two years without finding anything that truly rehabilitated me, until I started working with Dr. Felipe. Since I began therapy for ankle and hip pain, the progress I’ve made in feeling relief and becoming more aware of my body has been encouraging. His thorough approach and trials of specific exercises have been the solution to not living in pain.
