Dr. Richard Zeller, .

Dr. Richard Zeller founded Five Pines Dental in 2016. Originally from St. Louis, he graduated from dental school at The University of Missouri Kansas City in 2011 and has called Portland home since 2012.

Dentistry combines Dr. Zeller's passions for art, craftsmanship, problem-solving, and serving people. In his practice, he focuses on honest communication, informative care, and using advanced technology and techniques for better patient outcomes.

Dr. Zeller's dedication to craftsmanship continues outside of the office, too. When he finds the time, Dr. Z loves working in his woodshop and dreaming up new projects. Some of his woodworking is on display at Five Pines, such as the sliding barn-style doors in our patient operatories and the bookshelf in our waiting room.

Along with his wife Catharine, you'll also find Dr. Z hiking, snowboarding, cooking, and going on adventures with their two kids.

Q&A With Dr. Z

Where are you from? 

I was born and raised in St. Louis, Missouri. I went to school in the Midwest as well, I studied business and math at Westminster College in Fulton, Missouri then went to dental school at The University of Missouri Kansas City. 

‍ 

When did you know you wanted to be a dentist? 

Growing up I loved building things and working with my hands. I went off to college focused on engineering but became more and more interested in healthcare. I ended up choosing dentistry which combined science, business and my love for mechanical problem solving. I really enjoy having a skill that helps people. 

‍ 

What is your practice philosophy? 

I want to help my patients make informed decisions about their dental care. It used to be the doctor just told you what to do and patients weren't really involved in the process. I think all of medicine is trending away from that. My goal as a dentist is for patients to understand all their options for treatment and then work collaboratively to find the best approach for their needs. 

‍ 

What's your favorite part about being a dentist? 

I enjoy being involved with my community, and as a dentist, you get to meet a lot of people and potentially help a lot of people. 

‍ 

What is your favorite thing about Portland? 

The people are great, food and beer are excellent, and I like having all the outdoor activities nearby. I also appreciate the climate and vegetation – everything grows well and suddenly I was such a good gardener! 

‍ 

What do you like to do when you're not at the office? 

I have lots of hobbies that keep me busy. Mostly working in my woodshop, maintaining my '96 Jeep, beekeeping and gardening. My wife and I enjoy hiking, snowboarding, cooking and traveling. 

‍ 

What's one thing people might not know about you? 

Craftsmanship is very important to me as a person and a dentist. I love to make things, and you can see some of my woodworking and concrete projects throughout my practice. I take a lot of pride in the things I create, and I love that dentistry fits in with that so well.

My favorite part about being a dentist is the unexpected nature of each day. I'm never bored and have the ability to help others...a win/win. 

‍ 

What is your favorite thing about Portland? 

My favorite thing about Portland is the food scene and the people. I've lived in a few other cities and none seem to compare. The forest is great too!

What do you like to do when you're not at the office? 

When I'm not at the office, I typically go to the dog park, play trivia, or work out. I really enjoy anything and everything requiring movement.
