Our Team of Dentists in Ottawa

We are extremely proud of the team we have assembled. We all share in the commitment to provide exceptional dental treatment and customer service to every single one of the people that entrust us with their care.

Clinically, the driving force behind our decisions stems from a holistic approach. We are mindful of the relationship between the teeth, the gums, the bone and the rest of the body. Simply put, we strive to optimize and maintain oral and overall health. With the new materials, techniques and technologies available, we can fully embrace the artistic side of our profession and create stunning smiles without ever compromising on the quality of care.

We see the impact that a healthy, radiant smile has on our patients’ lives on a daily basis and this has reinforced our commitment to the advanced clinical approach that allows exceptional aesthetic dentistry to be achieved. Our team calls upon their years of continuing education and experience to consistently deliver healthy and natural-looking smiles.

From the point of view of overall experience, we are committed to making our patients’ time with us as relaxing, convenient and welcoming as possible. We work continuously on improving that experience by listening to what our patients say and putting into place the recommendations that help make our practice be as good as it can be!

Our shared vision was put into place by Drs. Prehogan, Dr Rosenberg and Lewinshtein. They incorporated the lessons from their dozens of years of collective practice experience into the philosophy that guides all of our efforts.
A large part of our philosophy is built around the concept of personal care. We enjoy having the opportunity to get to know each and every one of our patients, and conversely, having them get to know us. To help that process along, we have dedicated some space here to introducing ourselves.
