What our patients say about Flex Physical Therapy

  • I arrived at Flex Physical Therapy with a significant shoulder injury that I had left untreated for over six months. My physician prescribed steroids and an X-ray before referring me for physical therapy. I chose Flex due to its reputation for excellence, professionalism, and integrity. I found all the aforementioned to be absolutely true. Dr. Lagonigro and his team all contributed in meaningful ways to meet my treatment goals. A plan was outlined clearly at the onset and carefully monitored and adjusted accordingly throughout treatment to ensure the best outcome. I have a new shoulder! I am completely satisfied with my experience and the exceptional care I received at Flex PT. I cannot recommend this practice highly enough. Thank you, Lu, Maggie, Alyssa, Marissa, Zoran, and especially Dr. Raffaele Lagonigro!

  • When I first came to therapy I was very nervous and stressed as I had never experienced so much back pain and immobility ever before. However, from my first visit I felt the calmness and positive energy that pulses throughout the facility. I felt very welcome and sincere concern for my discomfort. The assistants were very helpful and accommodating – always checking that I was doing OK. The therapist never rushed and was immediately able to identify my specific trouble spots. Through massage and other techniques I was greatly improved. My pain went away and I felt back to normal after only a few weeks. I was so worried I would never be able to enjoy the holidays but now they will be the best ever.

  • I started Flex PT 2 ½ weeks after a knee replacement. I had 2 weeks of home PT prior to coming and was walking with a cane very slowly. Even though I lived very close (1/2 block), I need transportation which was provided by Flex. By the 3rd week of PT I was walking there with the cane and in the next 3 weeks I did not need a cane. Without PT I am sure I would not have progressed that far. Dr. Raffaele always answered all my questions and the staff is all very pleasant. Physical Therapy is not always easy and can be uncomfortable at times but you must focus on the end product. I am now enjoying gardening, volunteering and having returned to water aerobics at the YMCA. I thank Flex PT for all their help and support.

  • My experience at Flex PT was wonderful. The staff is upbeat and helpful and the therapist was very knowledgeable and passionate about my progress. The surroundings are spacious and bright and the equipment is top notch! I began PT at Flex several days after knee surgery. (I received no home PT but came straight to Flex). My first visit focused on improving my range of motion, my pain level was high. The therapist was reassuring and patiently guided me towards my goals. Today after three months with Flex, my pain level is zero, my range of motion is great and my outlook for a full recovery is sunny. I would recommend Flex Physical Therapy without reservation!

  • My journey began 2 weeks after having my ligament repaired on my right knee. I called Flex PT and the first person I spoke with was Luanna, who was very welcoming and explained the process from start finish. My first session was pain but I was in great hands working with Zoran, he explained the exercises and treatment plan. As I returned to work a week later I changed my days for PT and I began working with Raffaele who was equally knowledgeable and kind. The entire team is great and understanding. Two months later I have finished all my sessions and I am back to my “normal activities” without pain. Hopefully I will not be back but if I need physical therapy I will be back!

  • Overall, my time here at Flex PT was pretty great. After having surgery on my shoulder back in June, I found out that I needed to go to physical therapy. I was pretty scared at first, but walking in my first day, I felt very welcomed. I would be lying if I said I didn’t have a good experience here. Coming in 3 times a week and doing exercise became second nature. It felt great knowing that after putting in the work I’d be able to return back to sports. I’ve been involved in sports my whole life and being away from it for this long was definitely challenging. Flex PT was luckily a great choice and I’m glad I got to spend my recovery time here. The small group of people who work here are all very nice and you get to know them while you’re here. I’m glad to finally be finished, but if I ever get injured during sports and I need therapy again, I’ll be coming back here for sure.

  • Happy to come here. Very pleasant staff and I am making improvements! Great parking in the shade. Very friendly. Can walk better without help and I feel more stable. I have more confidence in moving around. Thank you!

  • If you are looking for an exceptional physical therapy facility with a staff of experienced, compassionate and caring professionals lead by Dr. Raffaele at a first class equipment center, turn to Flex Physical Therapy. Having been diagnosed with adult scoliosis and told that physical therapy was an essential and important path to my looking and feeling better as medication could not reverse my condition. So with dedication and determination from Dr. Raffaele and his staff, I have found improvement in my posture, balance and muscle strength thanks to the incredible planning and experience offered at Flex Physical Therapy.

  • Before starting PT I was very limited in my walking, standing and what I would wear. Now I can walk and stand almost 2x more than I was and I can finally wear some of the clothes that would hurt my neck before! The stretches and workouts I would bring home made a huge difference on my days off or when I was sore. PT helped very much and I will bring all I learned to college!

  • I had great difficulty moving my neck and left shoulder. I had trouble driving, reaching into the back seat, and buckling the seatbelt. The pain was excruciating and woke me up numerous times during the night. After a few sessions at Flex, I was much more mobile and experiencing some relief from the pain during the night. The physical therapists taught me exercises to do at home which really helped in between sessions. I had a phenomenal experience at Flex Physical Therapy. The therapists are hands on and watch as you perform the exercises during your session. I recommend Flex Physical Therapy highly!

  • One morning I woke up with excruciating pain in my left shoulder blade. I was in so much pain that I could hardly breathe. For my job I have to sit in front of a computer for about 10 hours a day. I was in so much pain that I couldn’t even sit still for more than 5 minutes at a time. My chiropractor recommended Flex Therapy. Raffaele has been a miracle worker. He personally worked with me one on one and provided treatment appropriate to my needs. In my case that included simultaneous heat & TENS treatment, followed by a deep tissue massage, which loosened up my tight shoulder. He had me working with weights, Thera-bands, & pulleys to help strengthen my shoulder and gave me exercises to do at home in between therapy sessions. I felt a marked improvement after only a few sessions. I just completed my 14th and final session and feel great. I am able to sit in front of my desk and work again. I just make sure to get up about every half hour so I don’t get stiff. Raffaele also gave me some Thera-bands to exercise at home with. The entire staff is very friendly & professional. I highly recommend Flex therapy.
