Meet Our Doctor

Dr. Andrew Dietrich is devoted to creating beautiful smiles that are unique to each patient's needs and that are above and beyond their expectations. His goal is to provide the highest quality orthodontic treatment in the shortest amount of time with the highest level of comfort for the patient. He enjoys building relationships with his patients and their families but the most exciting part of his day is seeing the ecstatic reactions of his patients when their braces are removed and they see their new smile for the first time.

Dr. Dietrich has been practicing with Dr. Hilliard since 2009 and loves the collaboration of working with such a skilled and accomplished professional. In fact, it was Dr. Dietrich’s own wonderful orthodontic experience with Dr. Hilliard that first sparked his interest in orthodontics as a career.

At the University of Florida, Dr. Dietrich received the coveted Alpha Omega Award for graduating first in his dental school class. He is a published author of dental research and has lectured to local study clubs, continuing education groups and the Traviss dental assisting program. In the future, he would like to follow in Dr. Hilliard's footsteps and lecture to a national audience. He is especially proud of his Board Certification which has served as an important extra step in furthering his knowledge and skill-set. He actively seeks out the latest proven orthodontic methods and technology to integrate into our practice and he recognizes that learning is a lifelong process.

Dr. Dietrich is a Lakeland native who returned to the area after completing his education. He graduated from Santa Fe Catholic High School where he played both baseball and basketball. You have probably seen him around town shooting hoops at the YMCA, hitting golf balls into the wrong fairway at local golf courses, or enjoying dinner and a movie with his wife, Bobbie. Perhaps the most comical scene you may catch is his attempt to walk all three of his dogs at the same time around Lake Hollingsworth. Dr. Dietrich is a huge Gator fan and he attends most of the home football games with his wife and his parents, Larry and Debbie. He is proud to be practicing in his hometown and loves being part of the community.

Meet Our Staff

In our office, I help out by answering phones, printing and mailing letters, and working hard to schedule the most convenient appointment times for our patients’ busy lives. Like everyone else who works here, I love doing everything I can to provide our patients the most rewarding and caring orthodontic experience possible. Our patients are incredible! They are all so unique and fascinating, and I feel very lucky to have such a wonderful career. My daughter, Ariana, is the light of my life, and I love spending as much time as I can with her. I am at home anywhere in the outdoors, and I love sitting by the fire and relaxing.

As one of our orthodontic assistants, I spend my days in our practice by helping our doctors provide our patients gorgeous and life-changing smiles. My favorite part of my job is building great relationships with the people in our chairs, and I love being a part of their incredible journey to a bright and beautiful new smile. Our doctors are great because they keep the atmosphere as laid back as possible, and they are always teaching us new things that help us be better at what we do for our patients. I enjoy shopping, spending the day on the boat, fishing, spending time with my little boy and being with my family and friends.

I have the awesome job of fabricating the orthodontic appliances that are going to help our patients receive the most beautiful smiles. We are in the business of giving our patients healthier and happier lives, and I am very fortunate to be a part of such a positive and beneficial experience that we provide to our family of patients. I have an amazing family at home, and it consists of my husband, Michael, and our kids, Trevor and Maddie. We also have a cat named Pumpkin and a dog, Crash. I love to travel, hang out at the beach, bake some delicious food, and spend my free time with my family and friends.

In addition to assisting our doctors with providing phenomenal patient care, I also act as a clinical coordinator for our practice. Whether I’m helping to make sure our clinic operates efficiently or working one-on-one with our amazing patients to help them look and feel better, not a day goes by that I am not excited to come to work. My husband, Tommy, and I have two furry children – our dogs, Sadie and Brandy. When I have spare time, I love fishing, boating, gardening, and generally just doing anything outdoors, especially when the sun is shining.

As our financial coordinator, I make sure our accounts receivables are in good order, and I do everything I can to ensure our patients are getting the most out of their insurance packages. I absolutely love my job because I am helping our patients receive the orthodontic care that they need and deserve. Paying for orthodontic care is never easy on a family, and I feel fortunate to be able to help make our patients’ lives less stressful. I really love working with our staff and doctors because they all care so much for the people who come to us for treatment. I have been married to my husband, Steve, for 35 years. We have two daughters, Keely and Kaylen, who have given us three adorable grandchildren. We also have a dog and three adopted cats. In my free time, I enjoy cooking and watching the Tampa Bay Buccaneers and Devil Rays.
