Meet Dr. Nick Sigman, DMD

Dr. Nick Sigman, DMD, joins Star Dental Denver with more than 14 years of clinical experience and a simple priority: helping patients feel comfortable with their care. He believes a useful conversation begins with listening—what is bothering you, what you hope to improve, and what questions you would like answered. From there, he explains findings and treatment options in plain language so you can understand the next step. His style is calm, honest, and centered on the person behind the smile.

Whether you are keeping up with preventive visits, dealing with a painful tooth, or returning after time away, Dr. Sigman wants you to feel welcome asking questions. He approaches care as a conversation, with room to talk through your concerns and priorities. The goal is a clear understanding of your oral health and a plan you can feel informed about, without feeling rushed through the explanation.

Care with the whole picture in mind

His clinical background spans restorative care, crowns and bridges, removable dentures, tooth extractions, emergency dentistry, and the management of gum disease. That range of experience helps him consider how an immediate dental concern fits into the bigger picture of your mouth. He also enjoys helping patients maintain healthy teeth and explore cosmetic improvements when those are part of their goals.

For patients thinking about dentures and denture repair or facing a possible tooth extraction, clear explanations matter just as much as the procedure itself. Dr. Sigman’s approach gives patients space to discuss what treatment involves and bring up practical questions. Patients with an urgent concern can also learn about the practice’s emergency dental care and contact the team about an appointment. You can read about these services before your visit, then bring your own questions to the conversation with Dr. Sigman and the Star Dental team.

Education and a Colorado career

Dr. Sigman earned his dental medicine degree from Southern Illinois University School of Dental Medicine in 2012, after completing a bachelor’s degree in biology at the University of Kansas in 2007. As a graduating dental student, he received the Wells Senior Student Award for Excellence in Dental Anesthesiology.

His Colorado career has included caring for patients in Boulder, Denver, and Aurora, including a Medicaid-focused practice. He founded Performance Dental Center in Boulder in 2016 and owned the practice through 2025. He has also contributed to his local professional community through the Boulder/Broomfield County Dental Society, serving as treasurer in 2018, vice president in 2019, and president in 2020.

Outside the office

Outside the office, Dr. Sigman enjoys cycling, hiking, and spending time with his wife and their dog. He appreciates the outdoor life that makes Colorado feel like home and brings the same approachable, down-to-earth spirit to meeting patients at Star Dental Denver.
