What our patients say about us
Dr. Sigman is so nice and caring, plus, he takes the time to explain all that is happening with your mouth. They also don't try to "up-sell" you on a hundred things you don't really need like so many dentists now-a-days. I won't be going anywhere else.

I love this place! Everyone is so nice and helpful. If they don't know the answer to a question, they will take the time to find out the answer and actually follow up with you to give you the answer. They took great care of my great!

I really had a good experience - they even got me in on the same day for my toothache and explained exactly what I needed. 5 stars for this place - I also appreciated the relaxed vibe in the office.

Nicholas Sigman, DMD

 Nicholas Sigman, DMD

Dr. Sigman has always wanted to live in Boulder, CO, so starting his own practice here has allowed him to live the dream!

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 Academy, the Colorado Dental Academy, the Academy of General Dentistry, the Boulder/Broomfield Dental Society, and the Denver Implant Study Club. 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 Boulder since 2012, and he opened Performance Dental Center in 2016. He loves meeting and interacting with all the awesome people in Boulder and helping them achieve their health goals.

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.

Addie Reed and Slash Sigman - Co-Directors of Clinical Morale

Slash and Addie have been with Performance Dental Center since the first day, and while they don’t have any formal training, they’ve completed thorough on-the-job training. They love getting to meet the patients, and they’re rewarded for their hard work with daily treats and belly rubs.

When they’re not at the office, they can be found enjoying bones, walks, and long naps with their owners.
