Meet The Dentists

Our highly-trained doctors are here to serve you. We currently have three dentists on staff, which means three doctors available to assist in emergency situations, different sparkling personalities, three “second” opinions for our patients… and one unwavering commitment to serving your specific needs in the best possible way.

Dr. Raleigh Pioch

After graduating from dental school at the University of Michigan, Dr. Pioch knew what he had to do to provide great patient care: open his own dental office in Oregon City. He wasn’t content to do things someone else’s way. He knew he had the skills to make amazing and compassionate patient care a reality. After searching around the country for the perfect place to open a practice, Dr. Pioch settled on Portland, Oregon. Since 2007, Dr. Pioch has brought his proven skills and experience to Oregon City. At Pioneer Dental Group, you’ll have the chance to work with a respected, skilled, compassionate, and successful dentist who values you and your health above all else.

A Dentist for All Patients

Dr. Pioch is dedicated to providing all his patients with exceptional dental care. He sees all patients from infants to seniors and promotes family dentistry. Instead of making multiple trips to and from a variety of dental providers, you can have all the work you need under one roof.
To serve you best, Dr. Pioch furthered his dental education at the University of Toledo Medical Center, where he gained extensive experience in pediatric dentistry, oral surgery, and endodontics. He continues to participate in further education to keep up to date with the latest technology and techniques in dentistry.

Dr. Cheah enjoys taking time to educate our patients on their dental health and the latest options for any treatment they may need.

When not taking care of our patients, Dr. Cheah enjoys spending time outdoors with his family camping, hiking, and biking.

Dr. Bradley

Dr. Bradley was born and raised in Portland, Oregon. He attended Oregon State University and graduated from Oregon Health and Science University School of Dentistry. He attributes his love of dentistry to his childhood dentist and mentor as well as his experience after college volunteering in Costa Rica where he helped provide free dental care to underserved areas. Outside of providing excellent care to all of his patients, Dr. Bradley enjoys traveling, skiing, hiking, and spending time with his family and dog.
