Meet Our Team

Nestled in the heart of the Russian community in Portland, Powell Family Dental Care has been operating since 1996. Our patients and staff are our family, and care deeply about the patients they serve, frequently taking on the important role of dental educators. Our office staff is warm and friendly, and can help solve any scheduling or billing predicaments.

It’s All In The Family

We boast two dentists, a husband and wife team, each with more than 25 years of experience in dental practice! Both our dentists are very experienced in the general services they offer: Dr. Dontsova typically focuses on younger patients and orthodontics, while Dr. Victor caters more to adult restorative dentistry & denture services. In addition, both firmly believe in their practice slogan, “Creating Beautiful Smiles for Everyone!”

Dr. Olga Dontsova, DDS

Dr. Dontsova has been practicing dentistry since 1990 and has completed advanced degrees and training in Ukraine and Germany as well as the United States. She graduated from Loma Linda University School of Dentistry in 1996 and joined her husband in private practice. She has always been passionate about treating children, and she furthered this passion by expanding her education into orthodontics. She has completed Progressive Orthodontics classes and the Master Program of Orthodontics from International Medical College, Germany. She is an Invisalign Preferred Provider, and is constantly taking continuing education classes and webinars to stay up to date with the latest technology and scientific advancements. 

In addition to general dentistry and orthodontics, Dr. Dontsova can also help you with cosmetic dentistry, implants, and Botox for TMJ/TMD. 

While their busy practice means the doctors have limited free time, they love to spend what precious time they do have with their boys, Alan and Etan, and they love to travel as family. Always active, they make sure to find time for each other, and for friends and family.

Dr. Victor Khlevnoy, DDS

Dr. Khlevnoy, or “Dr. Victor” as his patients call him, has also been practicing dentistry since 1990. His original training and degrees were in Ukraine, but after moving the United States, he chose to complete additional training and a secondary degree at the Loma Linda University School of Dentistry in California, from which he graduated in 1994.

He has also completed the American Academy of Implant Dentistry Maxicourse in Las Vegas with Dr. John Minichitti. This is a highly respected implant education program, and has greatly helped to widen our services and help our patients with their complete dental needs. Dr. Khlevnoy’s meticulous treatment planning and 20 years of experience are irreplaceable.

After hours, Dr. Victor enjoys the great outdoors and hiking. He and Dr. Dontsova travel whenever they have the chance. They have two sons, Alan and Etan, both of whom went to Lakeridge High School in Lake Oswego.

At Powell Family Dental, our dentists are members of the American Orthodontic Society, the American Association of Dental Orthodontics, and the Invisalign Study Club. We are committed to continuing our dental education, even completing more continuing education credits annually than are required. We go above and beyond to make sure we provide the best care and the most recent techniques for our patients.
