As Founder and Owner of Human Function and Performance, I have made it my life's purpose to redefine the way physical therapy is approached in the Dallas, Texas region. When I first moved from the Northeast to Dallas I immediately knew this city was the place I would call home. However, there was a major problem. Physical therapy as a profession was decades behind what I was used too. Rather than seek out a physical therapist to help uncover root causes of pain, physical therapy was focused on relieving symptoms. Getting rid of pain is important, but understanding why it develops in the first place is most important. I have made it my mission to help patients, athletes, clients and anyone who is interested, understand how their body truly works. That way, they can take back control over how they feel. It is common for individuals to get stuck going from Doctor to Doctor receiving a short term pain fix, with no strategies for creating long term change. At Human Function and Performance we have created an environment where patients get better faster and achieve lasting improvements, all with less time spent in the clinic and more time performing the activities they love.

My passion for physical therapy comes from my love of sports and interest in what helps athletes perform their pain-free best. As a former collegiate athlete, I understand the frustrations with having to sit out due to injury, or the aching and nagging pains that prevent us from performing to our fullest capacity and enjoying our favorite activities. I fully believe in our Human Function and Performance model for not only eliminating pain, but also creating long-term strategies to improve your movement and function. Whether you are an avid runner, Sunday afternoon golfer, CrossFit champion, once-or-twice-a-week exerciser or anything in between, I want to give you the tools to return to your activity of choice with an all-systems-go attitude. Not only functioning like you were before your pain but performing even better.
