Victor F.
This place is great. The staff is super welcoming and professional.They took the time to explain my specific treatment plan and put me at ease. They helped me regain function while helping to build strength in the injured area. Though my injury was pretty significant, I was able to make a full... recovery over the course of treatment.I would highly highly recommend Professional PT to anyone with an injury or post more
a very satisfied C.
I came to Professional Physical Therapy after surgery for a torn meniscus. My therapist, Jonathan, is outstanding. He is easy to talk with and his instructions are clear, concise, and encouraging. He conducted an evaluation prior to the start of my therapy, listened to my concerns, and provided... explanations for actions taken. Jonathan designed a program of exercises to help my healing process. The therapy was very effective in relieving my symptoms and improving my mobility. The support team is also very responsive and helpful. The facility is designed to be effective, with a clean, tidy and orderly appearance, along with convenient parking. I would highly recommend Jonathan at Professional Physical Therapy to anyone looking for excellent more

Jeannine Santarelli H.
I tore my ACL and Meniscus skiing back in January and needed to do pre and post surgical PT and immediately started seeing Dr Jon. There have been a few set backs following my surgery and Dr Jon continued to push me, keep me focused and most importantly kept me positive! On the days I was... frustrated and just wanted to give up he pivoted from being my physical therapist to my mental therapist :-) and I will be forever grateful for that. I highly recommend Dr Jon and the entire Professional PT staff!read more

Have been working with Dr. Jon for over a month now with post surgery knee rehab. Dr. Jon is positive and consistent, and every time I finish my sessions I feel like I’ve made solid progress into fully recovering from my injury. Always moving forward, never monotonous is how I would describe this... practice. Thank you Professional PT!read more

regina C.
My experience at this PT center has been wonderful! When I began therapy just a few months ago, I struggled to walk due to severe knee pain. I never imagined the progress that I've made and the confidence I am experiencing .Jonathan's knowledge and skill account for my success, but more than... that is his compassion and untiring encouragement. The site's environment reflects a commitment to team work and true concern for all patients. I would highly recommend this team!read more

The therapists were outstanding. Jonathan was patient and I never felt overworked or in pain. I would definitely recommend professional Physical Therapy to my family and friends.
Laurie K.
I was having a great deal of pain eating due to TMJ problems. I couldn't open my mouth wide enough to eat comfortably and without pain. My TMJ was out of alignment. Eric, a physical therapist trained to relieve patients of TMJ pain was amazing. His expertise and gentle manner reassured me that I... will heal completely and be able to eat comfortably. He gave me accurate exercises to do daily and he also worked on my TMJ at each session helping it heal. In less than 2 months I was pain free and eating comfortably. Thank you Eric for everything that you did for me! I highly recommend you to anyone who is suffering from TMJ more

Professional PT provides me with "professional" services in a one-on-one fashion. I like that. I'm seeing great results after just a few sessions, just as I was told. I would recommend anyone to Glen and Eric.
