Hello. Welcome to Atlas Dental!

Our mission is to make quality dentistry accessible and be known for phenomenal patient care. 

We seek to make quality dentistry accessible to our patients, our community, and globally. For our patients, we offer extended hours and weekend appointments, flexible payment plans, and utilize technology to provide conveniences such as online appointment booking. In our community, we provide free dental days, smile makeovers and oral health presentations. Globally, each patient that comes for a cleaning receives a biodegradable bamboo toothbrush and another is donated to a non-profit to support a 3rd world country. 

In order to be known for phenomenal patient care, we invest in highly trained staff as well as utilize the latest technology. This includes exceptional customer service for every dental visit, heated  massage dental chairs, ceiling TVs and intraoral cameras for patient education.


Hieu Pham, DMD

I am a dentist practicing in the Portland and surrounding area. Born and raised in Portland, I did my undergraduate studies at Portland State University where I earned a degree in Public Health, and graduated from OHSU's School of Dentistry.

I believe that dentistry is a perfect blend of art and science. I love the challenges, solving patient's problems and creating smiles that people can be proud of. 

One of the things I enjoy the most about dentistry is the ability to help people. Last year I went to Vietnam on a dental mission trip, and it was one of the most rewarding experiences I have ever had. 

When I'm not at work, you can usually find me dancing somewhere. I have been dancing since 2000 and travelling to compete and judge since I  was 17 years old. I strongly believe in following your passions with an impeccable work ethic, which helped me continue to dance during my pursuit for higher education. Recently, I began to teach workshops telling my story of balancing life with college, in hopes that my story inspires others to pursue their passions.
