Dr. Nicholas Sigman, DMD

Dr. Sigman has always wanted to live in Boulder, CO.

After receiving his undergraduate education from the University of Kansas in 2007, he then went on to complete dental school at Southern Illinois University School of Dental Medicine, where he received his Doctor of Dental Medicine (DMD).

He is a member of multiple organizations, including the American Dental Association, the Colorado Dental Association, the Academy of General Dentistry, and the Denver Implant Study Club. Most notably, he is the 2019 Vice President of the Boulder/Broomfield County Dental Society and a recipient of the peer-nominated 5280 Best Dentist Award for 2018 and 2019. Dr. Sigman has received recognition from the Seattle Study Club as well as the Horace G. Wells Award for Excellence in Dental Anesthesiology. He is also the only dentist in the Boulder area who is a member of the Academy of Sports Dentistry. 

Dr. Sigman has been practicing in Colorado since 2012. He loves meeting and interacting with all the awesome people in Aurora and helping them achieve their health goals. In addition, he has acquired co-ownership of successful family dental offices in Denver, Colorado. 

Outside of dentistry, Dr. Sigman enjoys rock climbing, riding his bike, hiking, and skiing. He also enjoys spending his time with his black lab, Slash.

Dr. Jaime White, DDS

Dr. White was born at Minot Air Force Base in Minot, ND. Both of her parents were on active duty, so they bounced around for several years before settling in Colorado Springs when Dr. White was twelve. She graduated from Air Academy High School in 1995 and moved on to Colorado State University in Fort Collins. There she obtained a Bachelor of Science in Psychology in December of 1998. She began dental school at the University of Maryland in the fall of 1999, graduating in May of 2003. While in dental school, Dr. White had her first child, Tehnley, in August of 2002. After graduation, Dr. White wanted to move home, so she accepted a position in the General Practice Residency program at the VA hospital in Denver. She completed her residency in June of 2004.

Dr. White used to have hobbies such as playing tennis, hiking and hanging out with her dog, Kevin. However, her free time is now spent shuttling four children to their various activities.

Dr. White maintains memberships in the American Dental Association, the Colorado Dental Association and the Boulder/Broomfield Dental Society. Her goal is to decrease the anxiety that seems to come along with maintaining healthy teeth and gums. She does that through education, understanding and conservative care. Dr. White completes a lot of cosmetic treatment and loves it, but is quick to differentiate between cosmetics and necessary treatment and to explain the risks of both. Dr. White believes prevention and regular checkups are the key to lifelong dental health. She also understands that not everyone loves going to the dentist and spends a lot of time trying to insure that each patient finds the environment as comforting as possible.
