Meet Our Team

Dr. Theron Manson purchased our practice in 2012 from the previous retiring dentist, James Soine, DDS. We’ve kept the same philosophy of care as the previous owner, which is why so many of his patients have stayed with Dr. Manson after coming to our office for over 40 years.

Meet Theron Manson, DDS

Meet Connie Manson, DDS

Dr. Connie Manson grew up in Seattle and spent many happy years at the University of Washington obtaining a BA in English Literature and a BS in Biochemistry. She then found herself sitting next to Theron in dental school and the rest is history. Connie received her Doctorate of Dental Surgery in 2002 and dedicated her career caring for under-served families all around Seattle.

Cheering on her boys at their sporting events is one of her all-time favorite activities. Camping, hiking, and enjoying a good book are also high on her list. If she is not in her garden, you may find her volunteering for the PTA, taking a slow run around the neighborhood, or trying to convince her husband that the backyard could sure use some chickens.

Meet David Chi, DDS

Dr. David Chi grew up in Kirkland and is happy to return to practice
dentistry in his hometown. After receiving his Bachelor of Science from
Northwestern University, Dr. David pursued a career in management
consulting before returning to Seattle to attend the prestigious University

and surgical extractions of impacted wisdom teeth.
Outside the office, Dr. David enjoys spending time with his wife and
friends, traveling, and enjoying the outdoors. He has a passion for tennis,
golf, hiking, skiing, scuba diving, and all else the beautiful Pacific
Northwest has to offer.
