Meet the Doctors

Dr. Quest Henry Quest, DMD

Dr. Henry Quest was born and raised in California to German immigrant parents.  The oldest of 3 children, he was ingrained with a very strict philosophy of hard work. Educated in the Bay area during the crazy sixties, he graduated high school as a junior and immediately joined the United States Air Force as a Dental Assistant.

After serving in the United States Air Force for four years, 2 of those in Japan, Dr. Quest then earned his Bachelor of Science degree in Biology at Portland State University.  He then went on to Oregon Health Sciences University School of Dentistry, graduating in 1989. Dr. Quest then returned to the Armed Forces, enlisting in the Army, and returned to his family’s native country of Germany. He spent three years in Germany, watched the fall of the Berlin wall and prepared service members going to Iraq for duty.

Dr. Quest worked for corporate dental offices after the military and realized that patient care was not being addressed to his standards of care. So began Quest Dental, a personalized family dental practice initially located in a small parking lot strip mall. The current location of Quest Dental was constructed in 2002 and quickly grew a substantial, loyal clientele.

Dr. Quest has a beautiful wife, Leticia, two grown children and recently became an Opa to his first grandchild.  He enjoys traveling, is active on a bowling league and is a life member and sponsor of the NRA.  He has volunteered his dental services to the Veterans Mobile Dental van yearly, participated in the Stand Down event for military veterans and makes treatment of veterans in his own office a priority.

Dr. Quest Steffen Lassen, DDS

Dr. Steffen Lassen is thrilled to join Quest Dental as of January 2019. Dr. Lassen earned his Doctor of Dental Surgery degree at the University of Detroit Mercy School of Dentistry where he was honored to receive the Dean’s Circle scholarship award and was voted Class President by his peers. Dr. Lassen has a long history of dental and humanitarian service, which has taken him to areas such as Ecuador (where he learned to speak Spanish), Guatemala, Detroit, and Washington DC. In that vein and following graduation, Dr. Lassen accepted a position in a rural, Northern Californian community health center. Due to the lack of nearby dental specialists and sheer volume of patients, Dr. Lassen quickly became adept at practicing the full spectrum of general dentistry. We are delighted that he has decided to offer his extensive skills and compassionate nature to our patients here in Eugene. Dr. Lassen and his wife, Emily, have two young sons. They enjoy hiking, cooking, and playing classical music together.
