I went to Dr Cavallo's office from a personal referral and I am so glad I tried it! They are super helpful with my insurance (highmark PPO). They called to check my benefits for free, and have a great office. Dr C is wonderful, I came with low back pain, and he has a wonderful instrument adjusting device, the Ultralign, designed from NASA technology that worked wonders on me. He did not have to twist me, which I was very impressed with and like very much. My pain went away in a few weeks, and I will be going there for maintenance care for a long time to come. Thanks team!
