About Dr. Mark Dental

At Dr. Mark Dental, we believe great dentistry comes down to two things: quality care and the way you’re treated while receiving it. Whether you’re visiting for routine care, restorative treatment, or an unexpected dental issue, our goal is to make every experience feel comfortable, straightforward, and personal.

Dr. Mark Breinholt is proud to serve Bellingham and the surrounding communities with a confident, patient-focused approach built on trust, communication, and attention to detail. As a fluent Spanish speaker, he’s able to connect with and support more families throughout the community, helping patients feel understood, respected, and genuinely cared for from start to finish.

Dr. Mark Breinholt brings a thoughtful, patient-centered approach to dentistry rooted in quality care, clear communication, and genuine connection. In just three years of practice, he has built a reputation for combining excellent clinical work with a calm, approachable bedside manner that helps patients feel comfortable and cared for throughout their visit.

Dr. Mark’s connection to Northern Washington began long before he made Bellingham his home. After marrying his wife, who grew up near Bellingham, he moved from Arizona to the Pacific Northwest to build their life together close to the community she has always called home. Originally from Arizona, Dr. Mark grew up as the oldest of six children before serving a two-year church mission in Argentina after high school, where he became fluent in Spanish. Today, that experience allows him to connect more comfortably with Spanish-speaking patients and families and create a more welcoming experience for a wider community.

Dr. Mark earned his Bachelor of Science in Microbiology from Brigham Young University before completing his Doctor of Dental Surgery degree at the University of Utah School of Dentistry. Dedicated to continually improving his craft, he completed more than 100 hours of continuing education within his first year after dental school, what he jokingly calls his “à la carte residency.”

His passion for dentistry began through job shadowing and a fascination with the human body, but what continues to inspire him most is the ability to make a meaningful impact on people’s lives. Whether helping someone rebuild a broken-down smile or simply restoring comfort and confidence, Dr. Mark loves seeing patients leave able to smile, eat, and feel like themselves again.

He especially enjoys restorative dentistry, including crowns, fillings, and dental implants, and is passionate about delivering work that looks natural, feels comfortable, and lasts. Just as important to him is the experience patients have along the way, which is why he prioritizes respectful communication, honesty, and helping patients feel informed without ever feeling rushed.

Outside the office, Dr. Mark enjoys spending time with his wife and two children, taking his kids to the park, hiking, mountain biking, rock climbing, water skiing, listening to audiobooks, playing strategy games, and watching a good movie. Now settled in Bellingham, he and his family enjoy making the most of everything the Pacific Northwest has to offer. That balance between adventure, family, and personal connection is reflected in the warm, approachable atmosphere he strives to create for every patient.

From the moment you walk through our doors, our goal is to make your first visit feel easy, comfortable, and informative. We’ll take time to understand your needs, answer your questions, and clearly explain any findings so you feel confident moving forward. Depending on your visit, your appointment may include an exam, X-rays, and a cleaning, along with personalized recommendations tailored to your smile.
