About Dr. Konstantinos Megkousidis

Dr. Konstantinos Megkousidis was born and raised in Athens, Greece where he received his Doctor of Dental Surgery degree, graduating in the top 2% of his class. Dr. Kostas -as he prefers to be called- then worked for two years as a General Dentist in a couple of practices and the Athens Naval Hospital, where he served for a year. In 2021, Dr. Kostas left Greece's warm and sunny weather to move to Boston, MA, and follow his passion for Orthodontics. There, he earned a Master of Science in Dentistry and a Certificate of Advanced Graduate Study in Orthodontics from Boston University Henry M. Goldman School of Dental Medicine.

Dr. Kostas believes that Orthodontics goes beyond than straightening teeth; it improves facial aesthetics, offers beautiful smiles, boosts confidence, and leaves a lasting positive impression. Dr. Kostas also emphasizes the importance of educating his patients on their oral health and takes pride in fostering a warm and friendly environment where patients feel comfortable and supported throughout their orthodontic journey.

In his free time, Dr. Kostas finds joy in the natural wonders of New England – hiking the trails of New Hampshire, skiing the slopes of Vermont, and embracing the coastal serenity of Maine and the Cape. On his bucket list is to explore every U.S. state park and experience the diverse natural wonders across the nation.
