Mark Germack Endondist in Downtown Seattle

Mark Germack DDS


I was born and raised in Spokane, Washington. Like any young kid I had dreams of being a point guard for the Sonics. At the age of six I figured out that wasn’t going to happen and I set my sights on becoming a dentist.

I made it to Western Washington University and was committed to becoming a dentist. I graduated with a degree in Cellular and Molecular Biology and was then accepted to the dental school at Marquette University. After dental school, I returned to Washington where I owned a successful general practice in Issaquah for 10 years.

Having experienced some episodes of extreme dental pain myself, I could always relate to patients who were in distress. Even though I had a great practice I felt compelled to practice endodontics and surgery. I decided to apply and was accepted into the residency program in Endodontology at the prestigious Oregon Health and Science University.

During that time my research focused on antibiotics and the prescribing habits of dental practitioners. Our research was published in the Journal of Endodontics and was used to help develop the most recent presiding guidelines for dental infections.

We are very excited to be a part of the dental community in downtown Seattle and are sincerely here to be a resource for our patients and referring providers.

Traditional root canal therapy can be stressful and overwhelming.  I want to change that.

Dr. Vicky Nguyen


Vicky Nguyen, DDS, MSD (or “Dr. V” as she is known in our office) was born and raised here in San Jose, CA. She attended Notre Dame High School and Santa Clara University and naturally roots on the 49ers and Warriors. Dr. Vicky specializes in conventional root canal therapy, cases of traumatic injury, and surgical endodontics.

She values educating patients about their oral conditions, prides herself on her interpersonal/communication skills, and is well known in the office for her calming demeanor.

Dr. Vicky received her Doctorate of Dental Surgery from the Arthur A. Dugoni University of the Pacific School of Dentistry, graduating in the top 10% of her class and was inducted into the Tau Kappa Omega, Phi Kappa Beta, and Omicron Kappa Upsilon honors societies during her time there. She went on to attend the University of Washington’s prestigious Graduate Endodontics Program in Seattle, WA to receive her Certificate in Endodontics and Master of Science in Dentistry degrees. While there, she worked alongside renowned clinicians and scientists to perform research pertaining to pulpal inflammation that has since been published in the American Association of Endodontists’ Journal of Endodontics.

Dr. V is thrilled to be practicing back in the Seattle area and strives to provide the highest quality of dental care possible to her patients. She regularly attends continuing education courses to stay up to date with continuously evolving technologies and values minimally invasive techniques to best conserve a patient’s existing dentition. She has volunteered to provide dental services to underserved populations both locally and overseas and intends to continue to give back to her communities.

When not in the office, Dr. Vicky can often be found cruising around town with her golden retriever Murphy, golfing at one of the many beautiful local courses, snowboarding, or enjoying some of the fine cuisine that the Seattle area has to offer.
