Meet The Doctors

Dr. Mitchell Miller

Board-Certified Pediatric Dentist

Dr. Mitchell Miller is a native South Floridian and grew up in Boca Raton. Although his dental career took him to other areas, he is extremely happy to be back in Palm Beach County helping to make children smile.

He received his Bachelor of Science degree in biology from the University of Central Florida where he met his wife, Samantha. Venturing out of the warm weather, he moved up north to complete his Doctorate of Dental Surgery at Howard University in Washington, D.C. He furthered his advanced education by completing a general practice residency (GPR) at Newark Beth Israel Medical Center in New Jersey. After being away for a few years, he couldn’t wait to get back to his roots.

Dr. Miller and his wife moved back to South Florida and not even a week went by before they adopted a puppy—their jack russell named Jarvis. Dr. Miller worked as a general dentist, but quickly realized his love for pediatrics and passion for fostering a positive dental experience for children. Dr. Miller decided to pursue his specialty training in pediatric dentistry at Nova Southeastern University.

Dr. Miller loves all things ocean, including fishing and scuba diving. When not practicing dentistry, he can be found golfing, playing softball, and spending time with his daughter. Dr. Miller is a proud UCF Knight, and as a born and bred Floridian, he is an avid fan of the Dolphins, Heat and Marlins, but also has ties to the Patriots, Celtic, and Red Sox. Dr. Miller is looking forward to making going to the dentist a fun and enjoyable experience for you and your child!

Dr. Nickolaos Kallis

Board-Certified Pediatric Orthodontist

Dr. Nickolaos Kallis is thrilled to be a part of the orthodontics team and looks forward to meeting you! Dr. Kallis was born in New Jersey and grew up in the Tampa Bay area of Florida.

Dr. Kallis began his path toward dentistry at the University of Florida (Go Gators!) where he received a Bachelor of Science in biology with the highest honors. He then ventured up to chilly Boston to earn his Doctorate of Dental Medicine from the Harvard School of Dental Medicine, where he realized that orthodontics allowed him to combine his interests in patient care and problem-solving. He completed his orthodontic residency training at Nova Southeastern University, where he trained at the same time as Dr. Miller! After graduating from residency, he practiced in the New York City metro area, treating many families and connecting with the community.

Dr. Kallis returned to South Florida to make an impact in the community that he loves. As a board-certified orthodontist, he is committed to providing the highest quality of care for his patients and takes pride in seeing his patients have beautiful and healthy smiles. He is invested in building relationships in the community, with patients, local organizations, and other dental care providers.

When he’s not straightening teeth, Dr. Kallis enjoys traveling, trying new restaurants, spending time with his family, binge-watching a good Netflix series, boating, and attending sporting events. Dr. Kallis welcomes all new patients and looks forward to treating all of your family’s orthodontic needs!
