My name is Maria Molcut. I was raised in Ohio. As a young child I always loved science, art, and working with my hands. Dentistry is the perfect mix of all those interests. Another reason I decided early on that I wanted to go to dental school was because I knew how much of a difference having a great healthy smile made a difference in my life. I attended the Ohio State University for both my undergraduate and my doctorate of dental science. I practiced in Ohio for quite a few years while my husband finished up his residency and fellowship in Cardiology. We had ultimately decided to move down to Texas to be near family and for the better weather. We moved to Dallas in summer 2018 and have loved it here ever since. We are active volunteers in our son’s school and in our church. In my free time I enjoy working out, running, biking, swimming, trying new restaurants, and getting to know the city of Dallas along with my family. I look forward to serving the city of Rowlett and providing excellent dental care to all my patients.
