It is my sincere honor and privilege to work with patients from all over the country to help them achieve their hair restoration goals. I believe that it is important to spend time with patients to thoroughly understand their goals so I can do my best to not only meet but to exceed their expectations. I am proud to work in a clinic that is on the cutting edge in hair science. My experienced surgical team and I hold ourselves to very high standards when performing FUT and FUE procedures. We also perform Embryonic (Placental) Stem Cell Injection Therapy, which is the a non surgical option to increase hair density and promote new hair growth. We are the only clinic in Colorado that offers this non surgical option.

When I am not working, I partake in many outdoor activities including running, hiking, camping, fishing, boating, snowshoeing, and snowboarding. I also enjoy reading, particularly anything related to health and wellness. In addition, I make it a priority to spend as much time as possible with family and friends.
