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.
Serving active adults and athletes in North Miami Beach, Aventura, Sunny Isles, and surrounding Miami areas.

What One-on-One Actually Looks Like
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.
Sessions at our North Miami Beach studio. At-home visits are available across Aventura, Sunny Isles, and the surrounding Miami areas.
Physical Therapy that worked after everything else didn't
Real five-star Google reviews, many from people who had already tried other physical therapy or chiropractic care before finding Nex.
"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 and experience. 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 on how and why my body moves and reacts the way it does... It felt motivating to have a PT that was as invested in my success as I was."
"Just wow. 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 enjoy training. It wasn't about being dependent on Nex to get out of pain, but on getting on a system that made lasting impact. Forever grateful!"
"Felipe combines solid professionalism with sincere caring. He not only helped to get my recovery going but also helped me with the psychological challenges posed by persistent pain and sleep deprivation. He took me from the storm of pain and pills to an orderly path of steady improvement. Thank you Felipe."
"...I had been in pain for two years without finding anything that truly rehabilitated me until I started working with Dr. Felipe! What I like most and highly recommend is his thorough approach to understanding each patient's case and developing a strategy, including trials of specific exercises that make a difference..."
"I am in a planned program established for various areas of my body after suffering for many years and many therapists. I have never experienced his techniques before giving me immediate relief. I just cannot tell you how capable and wonderful he is. If you need therapy he is on a different level and you need to see him..."
"...He wanted to be sure that it was just a muscle strain as opposed to a problem in my back or other surrounding tissue... I am A 77-year-old very active woman and I've had many an injury and had to go to rehab. I have never had such a thorough, enlightening experience with a rehab doctor as I had This past week."
