Over the last 10 years, Dr. Oleg, Dr. Nikole, and their caring team have dedicated themselves to creating a very special place for the Eastside community to receive every dental service imaginable by the most experienced dental professionals. In fact, their dedication to friends and neighbors can be found right in the name of the practice; ‘425 Dental’ pays homage to both Eastside history and the area in which Dr. Oleg grew up.


425 Dental’s newest integrated dental suites feature the latest dental technology and are designed to make sure that their patients are getting the right care by the right people, conveniently all under one roof. With dedicated specialists in the same building and working together with general dentists, every patient benefits from integrated treatment planning; that means clearer communication between specialists and general dentists, shortened timeframes for completion of specialty procedures, and no need to travel from office to office.


From general dentistry to Invisalign, oral surgery to endodontics, and more, the entire 425 Dental family invites you and your family to start with us and stay with us.

What Sets Us Apart?

We want to ensure every single one of our patients is happy, healthy and comfortable in our office! We strive to focus on your individual needs to maximize the effectiveness of your treatment, and take pride that any dental service you may need, including those provided by a specialist, is available under our roof.

Experience personalized dental care

Our personalized care starts before treatment begins with no judgment or lectures. We give you as much or little information as you’d like, to allow you to make the best treatment choices. Financing and insurance are explained and estimates given. During treatment we’ll make sure you are comfortable and relaxed. After treatment, Dr. Nikole, Dr. Oleg or Dr. Sakai will personally call you at the end of the day to check up on you and make sure all of your questions were answered.

Each member of our team has years of experience in treating patients with the highest level of care. We strive to stay abreast of the very latest in technology and advances by regularly attending continuing education courses and seminars. We strive to help our patients achieve long-term dental health, and ultimately improve their quality of life.

All dental specialty work done in one place

We offer our patients the comfort and convenience of having any needed specialty dental work done in our office by our specialists. This means that you don’t have to go to another office, meet new people, worry about insurance eligibility, or try to schedule your own appointments with other doctors. All our specialists work closely with Drs. Oleg, Nikole and Sakai to provide you care in our surgical suite with the latest technology and sedation options. If there are any questions during consults or procedures, our doctors are right there to help guide you in the best treatment option and discuss with the specialist any special circumstances. Because all of our specialists are on the same charting system as our general dentists, our front office team can schedule your consults or treatment with the specialists just as they would your next cleaning. This also streamlines communication between the specialists and general dentists working on your treatment, allowing them to share notes and discuss quickly to provide you with the best care possible!
