What Sets Us Apart

All dentists are trained in the basic science and practice of dentistry, but it is our personal values and experiences that sets us apart.

I am Modoc

an enrolled member the Klamath Tribes of Southern Oregon. My personal values exist in relation to the cultural values that I was raised with as a Native American.

Those values include empathy, humility, respect and acceptance of the differences between people.

My practice of dentistry

is based on the core values of my cultural upbringing. Hard work, listening to others, respecting differences and sincerely treating people as I would like to be treated.

Celebrating diversity

has become a common theme in today’s culture, as an Indigenous person I understand and appreciate diversity every day of my life.

The only AADSM Dentist in Lane County

I currently hold the Qualified Dentist designation from the American Academy of Dental Sleep Medicine (AADSM).

AADSM is the leading national organization for dentists who treat snoring and obstructive sleep apnea with oral appliance therapy – an effective medical alternative to the traditionally-prescribed CPAP therapy.

I was the first from my family

to attend and graduate from college. I was also the first member of a federally recognized Oregon tribe to become a dentist.

As a first in these achievements there was no one ahead of me to provide guidance, support or mentoring in my educational and professional pursuits.

It was through hard work that I endeavored to persevere and accomplish my goals.

Dr. Dexter has a broad range of interests beyond the field of dentistry and medicine. He has a passion for the arts; particularly enjoying photography, architecture, and the design world. A proud supporter of local artists, he hosts quarterly photography shows in his office. Additionally, Dr. Dexter takes delight in food and cooking. He is a firm believer that food not only nourishes the body, but also the soul. Above all else though, what Dr. Dexter enjoys most is the constant joy of spending time with his children and grandchildren.

Behind our Logo: Medicine Wheel

The medicine wheel, sometimes known as the sacred hoop, embodies the Four Directions which symbolize dimensions of health and the cycles of life. The presence of the medicine wheel in my practice is a reminder of the fact that when you live your life in a circular pattern, there is no beginning or end.

It’s a reminder to live in health and wellness, and treat others with the dignity and respect that you would like in return.
