Reviews By Our Satisfied Clients

  • "I started seeing Dr. Cavallo after my orthopedic doctor recommended Physical Therapy. The personalized attention and instruction by both Dr. Cavallo and her staff was key to my understanding the proper form in order to target the correct areas. Dr. Cavallo would demonstrate and perform the exercises so I could understand what I would feel as I did the exercise, to ensure that I was doing it correctly and would not hurt myself. If something wasn’t feeling right, she would modify my positioning until it was correct. The number of clients in the facility is kept to a minimum so you are constantly monitored, and not just set off to exercise by yourself. Because of the personalized, caring and professional attention provided by Dr. Cavallo and her wonderful staff, my elbow pain has been resolved, and I am back to painless activity once again. Thank you Dr. Cavallo! I will continue to recommend you to all of my friends and family for PT needs."

  • "Last summer, I tore my Achilles tendon while running around the yard with my grandson. After having surgery to repair and reattach the tendon, I had to remain off of my feet for two weeks. After that time, I needed to begin physical therapy. Luckily, my Chiropractor, Dr. David Wallman, has a physical therapist working in his office. Dr. Cavallo provided expert care including various exercises, stretches, and strength training. In addition to being knowledgeable, she is also a kind and caring person who listens and understands her patient's needs. Mia assists and helps patients while doing their exercises to ensure they are doing them correctly and safely according to Dr. Cavallo's recommendations. I would not be in full recovery without Dr. Cavallo's expert care. I am able to walk, run, jump, and do everything I did prior to my injury. I would highly recommend Dr. Cavallo for any of your physical therapy needs.
    Thank you Dr. Cavallo and Mia!"

  • "I met Dr. Abby when I needed to rehab a broken shoulder. She put me through the paces but made it fun. I now have full range of motion back. Dr. Abby is now helping my husband with his neuropathy. It's a challenge because he also has limited vision, but he is progressing very well under her direction. Her staff is also a wonderful group of people."

    He has helped to relieve the pain from injuries we have sustained over the years. Dr. Wallman pays close attention to our need as we discuss proper diets, exercise, stretching, massage, and manipulation to best heal us. I highly recommend his expertise in the field of Chiropractic and Nutrition."

  • "In the spring of 2013, I was gearing up for running across the country with 4kforcancer. That summer I found Dr. Wallman and went in for treatment prior to the run and post run. I was doing extensive training - running 5 days a week (8-10 miles/day) over a month.
    A couple of years went by and I returned to him because I was really happy under his care. This past year I came in because I needed help during my training for participating in the Dopey Challenge at Walt Disney World running for L"
  • "After sustaining injuries from a car accident, I went to visit Dr. Wallman. I'm so happy to report that I no longer have to take NSAIDS/prescription medicines and my physical issues have been resolved! I've been able to return to work and function normally! I've been seeing Dr. Wallman for 5 years now and I would 100% recommend him to anyone who needs the help!"
  • "In March I fell on ice and felt like I broke a rib. I was living with unbearable pain, I never really believed in chiropractic work. I went to get adjusted Wednesday 6/7/17, that was the first time I felt better since March and haven't taken any pain medicine. I wish I went sooner, I can't believe how much better I am feeling!"
  • "Dear Dr. Wallman,
    As of this time I am happy to tell you that she continues to flourish at school and is now getting ready to head to University. I cannot tell you how you have changed our lives. For that I am eternally grateful. I'm sure by looking at the enclosed picture you don't see that girl that walked in to your office, but a happy young lady ready to take on the world. Thank you for saving my daughter and making a difference!"

  • "Dear Dr. Wallman,
    We want to thank you from the bottom of our heart for your passion and committment to our health. I remember the day I walked through your door, I had already had a feeling of defeat due to my level of exhaustion and pain. I was really at my lowest and felt helpless. From the first time we spoke, I felt like you heard me, something no previous doctor took the time to do. THANK YOU! When people ask me how I am feeling I now respond GREAT thanks to you. I tell people that you"

  • "I threw my back out doing yard work. I called the office and and was able to go in right away. When I got there, I looked like a question mark. After two treatments I felt much better. I would recommend Dr. Wallman to anyone."

    My greatest practice pleasure is integrating many types of treatments in one facility. Each type helps treat a specific condition, however, combining them together can create a much greater outcome for the patient.
