Orthodontists in Birmingham

Dr. Mackie is a metro-Detroit native and lifelong Michigander! She has always had a passion for dentistry, but most importantly she loves developing and maintaining personal connections with people. She decided to pursue a career in orthodontics so that she could spend quality time with a variety of patients and help give them the smile of their dreams.

She went to the University of Michigan and earned her Bachelor of Science degree in evolutionary anthropology with high distinction. She then stuck around U of M for dental school and orthodontic residency—making her a Wolverine for life! During residency, she obtained her Master of Science degree by researching CBCT biomarkers in the articular fossa for early signs of temporomandibular joint disease.

In her free time, Dr. Mackie enjoys spending time with her husband, Albert, and her friends and family. She and her husband love giving back to the community, traveling, attending Broadway musicals, and trying new restaurants!

Dr. Groth is a native of Metro Detroit and the son of a local dentist. He attended Cranbrook-Kingswood school and then Emory University in Atlanta, Georgia where he was an academic all-American. He was also a four-year varsity athlete, attending two NCAA national championships and earning multiple all-America swim awards.

He attended dental school at the University Of Michigan where he graduated at the top of his class. His main course of study at U of M was the leading edge of orthodontics: the benefits of robotically bent, custom wires in orthodontics. Quick to embrace new technology, Dr. Groth leads our team in harnessing the latest innovations in digital impressions.

His innovative thinking has allowed us to make our own clear trays for minor movement and then 3D print the models for aligners and retainers to save our patients money and treatment time.

As a Diplomate of the American Board of Orthodontics since 2012, Dr. Groth has lectured regularly to the second-year residents at the University Of Michigan School of Dentistry. He’s a published author, and his articles have appeared as the cover stories for the Journal of Clinical Orthodontics. He also speaks nationally on the benefits of 3D technology in orthodontics.

Dr. Groth enjoys running and cycling with friends and his wife Kelly. Both have a passion for running races in support of local charities, and you’ll see them running in their TDR t-shirts. They are the proud parents of two beautiful children, daughter Reese and son TJ.

Originally from Rochester Hills, MI, Dr. Julia Mastracci completed her undergraduate degree in Biopsychology, Cognition, and Neuroscience at the University of Michigan in Ann Arbor. Later, she earned her Doctor of Dental Surgery degree from the University of Detroit Mercy School of Dentistry, where she also received her specialty certificate and Master’s degree in Orthodontics. Dr. Mastracci is board certified by the American Board of Orthodontics, a distinction that reflects her commitment to the highest standards of clinical excellence and patient care.

Dr. Mastracci is proficient in using a variety of treatment techniques, including fixed appliances, clear aligners, and managing early interceptive, interdisciplinary, surgical, and craniofacial/cleft cases. She has also utilized cutting-edge technologies such as custom 3D printed brackets, TADs, miniscrew-assisted expansion, and soft tissue laser therapy.

Dr. Mastracci is motivated to have the same positive impact on her patients that her TDR orthodontist had on her when she was a kid. Being part of such transformative journeys for patients of all ages is truly inspiring. In her free time, she enjoys spending time with her fiancee Gino, taking her golden retriever puppy Cannoli for long walks, and soaking up the sun lakeside with her family.
