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. William Cheah

Dr. Cheah graduated from the University of Detroit-Mercy School of Dentistry in Michigan, where he practiced for 12 years. Dr. Cheah moved back to Portland with his wife & three daughters in 2014 and became a member of the Pioneer Dental Group team in 2018. 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. Nebeker

Since he was 12, Dr. Nebeker knew he wanted to be a dentist, and as a native of the Willamette Valley, he had no doubt he would stay and raise his own family here. After serving a 2 year mission trip in Paraguay, he attended Brigham Young University for his undergrad, where he met his wife. He then proceeded on to Oregon Health & Science University to complete his dental training. Dr. Nebeker’s favorite aspect of dentistry is seeing people feel confident in their smiles.

Dr. Nebeker has 4 kids and a black cat named Coconut. He enjoys fishing, watching and playing sports, reading (especially history), and anything to do with the outdoors, but his favorite hobby is spending time with his family.

Dr. Clow

Dr. Kenny Clow started his professional life as an accomplished Marine Corps combat instructor. He received numerous commendations, awards and medals before transitioning out of the Marines in 2009, but his desire to help others continued. He obtained his Bachelor of Science degree from Oregon State University and then his Doctor of Dental Medicine (DMD) degree from Oregon Health & Science University School of Dentistry. During this time obtained advanced training in implant dentistry & IV sedation.

Dr. Clow is experienced in many types of dentistry and enjoys helping patients achieve the smile they’ve always wanted. He is especially passionate about dental surgery, implants and is experienced with sedation dentistry. He has vast experience with dental implants, bone graftings and sedation with a goal of helping his patients receive the smile they want in an anxiety free dental experience.

Dr. Clow is a native Oregonian. He and his wife have been together since 2008 and have two beautiful little girls. He treasures his family time and together then enjoy hiking, camping, and playing outside.

Dr. Clow is licensed in Oregon, Washington, and Alaska. He holds professional membership with the American Society of Dental Anesthesiologists, International Congress of Oral Implantologists, American Academy of Implant Dentistry, American Dental Association, Oregon Dental Association, Academy General Dentistry and Multnomah Dental Society.
