A Little About Me

Hi there, thanks for stopping by. You can call me Dr. D.

I work as a family and sports medicine physician at the Mayo Clinic* in Jacksonville, Florida. I attended osteopathic medical school and treat sports injuries. I truly believe in the body’s innate ability to heal itself and the power of physical therapy to treat injuries. I prefer to focus on prevention instead of just prescribing medications.

Why Sportydoctor.Com?

I started this website as an at-home resource for my patients.

I am always making product and home treatment recommendations in the office and I thought it’d be a cool idea if my patients (and anyone on the web!) could have easy access to this information at home.

I want this site to be a resource for everything sports-medicine related! To that end, you’ll find lots of tips and tricks to prevent and treat injuries, stay on the top of your game.

My Mission

To help people reduce the need for drugs and tap into the body’s natural ability to heal itself by focusing on prevention and rehabilitation. Put even more simply, I want to provide advice to help weekend warriors and elite athletes alike stay active with non-surgical techniques and holistic treatment options.

Education and Credentials

I am a doctor of osteopathy. This means that I practice holistic medicine. I can prescribe Rx, but would rather correct issues at the source through preventative measures, like rehab and nutrition.

Personal Background

I am a primary care physician, but I’m also active and have a passion for sports. I have many years of training and experience in sports medicine. As part of my studies I completed a sports medicine fellowship.

My mother is a physical therapist and I was exposed to rehabilitation at an early age. I remember being fascinated in seventh grade anatomy lab while dissecting frogs. My interest has grown over the years. This made becoming a doctor a natural choice for me. I truly can’t imagine doing anything else!

I have a keen interest in sports medicine. I was a competitive volleyball player for eight years, and I remain an active weekend warrior. As a mommy to two small children, it’s in my best interest to stay healthy and fit! I love football and am a HUGE Gator fan. I also love spending time at the beach.

Sports Coverage

Not only do I see patients in the office, I also cover on the sidelines at local sporting events! I have been a team physician and covered football games at the Florida School for the Deaf and Blind, Terry Parker High School, Sandalwood High School, Edward Waters college and the Junior Development League.

My sports coverage experience is not just limited to football. I have also covered UNF Women’s and Men’s Soccer, UNF Basketball, the Donna Marathon, Triathlons, and FIVB Beach Volleyball (Olympic and professional level beach volleyball tournament).

I met three-time Olympic gold medalist, Kerri Walsh while covering a volleyball tournament.

Community Involvement

I enjoy being active in my local Jacksonville community. I have worked with athletic trainers and performed physicals for high school sports. I served as the medical director for the DONNA Breast Cancer Marathon.

I am a big advocate for concussion prevention and awareness. I was part of a team that provided concussion testing to young athletes at the Mayo Clinic. Here’s a video of me on the local news talking about this service and giving tips for spotting and preventing concussions.

I believe giving back is important. For that reason, I am a proud supporter of the following organizations:
