After receiving my undergraduate degree in Biochemistry from Texas Tech, I then proceeded to attend the Texas A&M Baylor College of Dentistry in Dallas, TX, where I earned my DDS in 2006. I have been providing the Hill County community with quality and attentive dental care since 2009.
I was born in Lubbock, Texas in 1978. I attended Lubbock Christian High School, graduating in 1997. I attended Texas Tech University, graduating in 2001. In June of 2002, I married my sweetheart, Kerista Harris. Kerista and I have two daughters, Ella and Kaitley. My family and I love to play golf together. I would describe myself as a technology geek – I love Apple computers and am always looking to add technology to my office or home.
I have always insisted that my patients be “treated like family” when they enter the doors of Cowan Family Dentistry. My staff has been praised for being friendly and courteous and is dedicated to making every trip to the dentist a pleasant one. The friendly atmosphere of our practice has put many patients at ease during a potentially anxious trip to the doctor. Because of this energy and compassion toward patients, we have become one of the Hillsboro community’s favorite dental practices.
In addition to prizing the way that my patients are treated, I also believe in practicing dental excellence at my Hill County practice. Patients will receive high-quality care through methods tested by dental professionals everywhere. By combining dental/periodontal care with practical patient education, I give my patients a smile that they can be proud of, and teach them exactly what they can do to maintain it.
In the interest of preserving the family-oriented environment of Cowan Family Dentistry, I’ve decided to extend my staff’s catalog of dental services to patients of all ages. From children age four, through folks that are already enjoying retirement, everyone in the Hill County area can enjoy a great checkup at Cowan Family Dentistry.
Outside of the dental practice, I enjoy time with a family of my own – a wife of over 12 years and two lovely daughters. As an active member of the Hillsboro community, I have served as the Chamber of Commerce Chair, President of the Hillsboro Rotary Club and am a Lions Club member. To relax in my down time, I will play a few rounds of golf or enjoy some classical music from my collection.
