Connor and Allison are both excellent, I have seen significant improvement in pain management and overall stability in my knee after only about two months. Connor has given me the information I need to go into my normal strength training program with good form, and has helped me determine the best ways to strengthen around my knee and hip. He’s also given me tools to use when I have pain flare ups for immediate relief. I am so glad I decided to make my first appointment and I’m grateful for the care and kindness shown to me through all my appointments since!

Excellent place for physical therapy. Therapists work with one person at a time so they are focused and engaged. They are knowledgeable and skilled. Best PT I've ever had. Allison is amazing. I keep her on speed dial!

I have been going to The Fitness Lab for several years. Started with PT for a shoulder injury and have since been doing personal training with them. I see Conner and he is fantastic, he has taught me so much about strength training and staying fit. 100% recommend them.

I’ve been seeing Dr. Kerri Tiller for the last month or so. She has been a godsend. She’s so patient and professional and knowledgeable. Dr. Kerri has all kinds of ideas on how to get me out of the low-back and hip pain I’ve been dealing with for months. I have pre-booked two times a week with her for the next couple of months… That’s how much confidence I have in her abilities. I have already seen some improvement. We are throwing everything at this, including dry, needling, and manual therapy. Thank you so much!

Dr. C. Marnin is an excellent physical therapist and has been very helpful to me in managing my osteoarthritic hip pain. I would highly recommend her: she is patient, encouraging, organized, goal-focused, professional, and competent. I have had several physical therapists in the past, and she ranks at the top!

The model for PT at The Fitness Lab is unlike any other physical therapy I have received. They prioritize functional mobility and movement in recovery rather than clinical exercises that would not be used in your day to day. My therapist, Will, was very knowledgeable and open to changing my treatment plan based on my goals and daily symptoms. I recommend The Fitness Lab to anyone wanting to recover quickly and build strength/confidence towards their individual goals.

I have thoroughly enjoyed my experience at this location. I have visited multiple times a week for about 3 months now, treating 2 separate injuries. Mel (Dr. Melanie Kos) has been awesome to work with. I appreciate her expertise and her awesome personality. Also, this Fitness Lab location has been a far better experience than I have had at other brands/locations in the past. The experience here is more one-on-one with a calm environment. The whole team here is awesome.

Could not be happier with my experience at the fitness lab. I have been having trouble with my back/neck for years. I have seen other PTs and tried just about everything. Melanie Koss was able to diagnose the problem day 1 and after a few months has gotten me back to being able to workout out consistently. Super easy to work with, she gave me a detailed plan and warm ups I can continue to do to keep the pain away. Very happy with my experience!
