Dental Staff

Thomas J. Chapman, DDS,

Hello! I am the founder and owner of Highlands Ranch Periodontics & Implant Dentisty. Dentistry is a second career for me. After twelve years in retail management, I decided that a career change was needed to fulfill my life. Opening and managing stores for Kids  R Us was just not what I wanted to do for the rest of my career.

After returning to undergraduate school to take courses needed to apply to dental school, I began to search for the right dental school for me. The University of Maryland Dental School was at the top of the list. It is consistently ranked as one of the very top dental schools in the country. It is also the very first dental school in the country! By the end of my first year, I had fallen in love with periodontics and the idea of saving teeth. Specializing became my goal.

I completed my residency in periodontics and implants at the University of Maryland. My family and I moved to Denver in 1996 and I began practicing periodontics! I founded my own practice in Highlands Ranch in 2002 after working for a very busy office for five years. My goal was to own a periodontal and implant practice where each patient is treated as a person, not just a "case". Our foundation core values at Highlands Ranch Periodontics & Implant Dentistry include excellent clinical care, effective two-way communication, strong ethics, and shared decision making in a comfortable and enjoyable environment for everyone. With the help of my staff, I am quite proud to say that we have achieved this goal! Owning my own practice allows me the time to spend with each of my patients so that I can get to know them, their goals and concerns. I enjoy acting as an advisor for my patients dental health and assisting them in achieving their long term health goals.

On the personal side, I am the very proud father of twins, Ashley and Ryan, who make Denver their home. It's hard to believe that they started first grade at the same time that I started dental school! Harper, our granddaughter, has enriched our lives beyond belief! In my spare time, I love racing my Formula Ford race car with Rocky Mountain Vintage Racing, traveling, cooking and exploring Denver's many fine restaurants. My wife, Stephanie, and I live in the Highlands neighborhood of Denver.
