  • "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.
