Dr. Rolfes

A highly regarded restorative dentist, renowned for his commitment to relationship-based care and exceptional reputation within the dental community, Dr. Rolfes serves his patients with a passion for improving oral health by combining advanced dental expertise with a personalized approach to adult patient care. He and his team understand the importance of building trust and lasting relationships, and their commitment to excellence has earned them the trust and loyalty of countless patients.

He is a life-long Cincinnati resident and is married to Karen, an accomplished Cincinnati oil painter. They have four children. His interests include most types of athletic activity which has lead to his role as Director of Dental Services for Xavier Athletics for the last 10 years. He also enjoys golf, as well as overall fitness, wellness, cooking, organic vegetable gardening, and relaxing in Northern Michigan every summer with family and friends.

With an educational path that was locally loyal, he attended St. Xavier High School, Xavier University and Ohio State Univ College of Dentistry. He has an extensive post-graduate education resume and has many years of involvement in study groups as a participant as well as a facilitator. This has included a visiting faculty role at the renowned Pankey Institute. He continues to enjoy mentoring younger dentists who have an interest in pursuing a similar path of excellence in the profession.

Dr. Koo

Dr. Koo is a mom, wife, and dentist – in that order, where people come first. The people-first philosophy translates to a deeper level of care for her patients. She’s always been career-driven, and professionalism is paramount, but what sets Dr. Koo apart as a dentist is a family-like connection and commitment to her patients. She offers a deeper level of care that includes looking at the whole mouth as it is now and how it will affect her patients in the future.  

Her kids and her own sleep journey are the driving force behind the creation of Breathe Cincinnati. She wants the same level of personalized care for you, but without fighting as hard for it as she did. Breathe Cincinnati is the marriage of all she learned about the mouth, breathing, and sleep and her people-first dedication to client care.
