“My goal in treating patients is to try to improve their health by restoring their function as close to normal as possible. If we can understand each persons' particular situation and goals, we can tailor a treatment plan to try and accomplish this. I get great joy in helping my patients improve their mobility, which is an important step to also improving their overall health, and ultimately their enjoyment of life.”
