Dentist in Bethesda, MarylandDr. Tassos Sfondouris

Dr. Tassos Sfondouris is a hard-working man with humble beginnings. He is a son of Greek Immigrant parents, who instilled the values of hard work, honesty, and integrity in him. His father came to the U. S. as an orphan at age 12 after he survived the June 1945 German Invasion and Massacre of Distomo, Greece. This unique experience growing up and the lessons taught to him by his parents shaped his personal and professional philosophies of “Do No Harm and Help Others.”

Dr. Sfondouris was born and raised in Annapolis, MD. He received his Bachelor of Arts Degree from Clemson University. He received his Dental Degree from the University of Maryland, School of Dentistry. Immediately following dental school, he completed a specialty Certificate in Periodontics with a Master of Science Degree from the University of Maryland. Following the completion of his periodontal training program, he completed a 2-Year Fellowship Training program in “Implants, Periodontics, and Prosthodontics.” This advanced dental training focused on restorative procedures such as single to full arch fixed and removable prosthetics, as well as esthetic dental procedures. Lastly, Dr. Sfondouris is a Clinical Research Associate at the National Institute of Health (NIH), where he is involved in the clinical trial, “Oral Microbial and Immunological Characterization of Patients With Immune Dysfunction.”

Dr. Sfondouris is a volunteer and leader in his dental community. He is the co-founder of a Spear Dental Study Club. This is a dental study club comprised of local area dentists and specialists who meet monthly to discuss various dental topics and case reviews, advancing their collective dental knowledge. He is currently the President of the Alpha Omega, International Dental Society, DC Chapter. Typically this is a 1-year term, however, he was asked and volunteered to complete a second consecutive term. Alpha Omega is the oldest international dental organization in the world and was founded in Baltimore, Maryland in 1907 by a group of dental students originally to fight discrimination in dental schools. Today with our headquarters in Rockville, Maryland, AO is primarily an educational and philanthropic organization.
