Dr. Roy Petras

Forty-plus years of dentistry in the town he has called home for 45 years — often caring for three generations of the same family.

Dr. Roy Petras was born and raised in South Windsor, Ontario. He completed his undergraduate studies at the University of Windsor before moving to London to attend the University of Western Ontario for dental school. After earning his Doctor of Dental Surgery degree, he returned to Essex County and settled in Amherstburg. He has lived and raised his family in Amherstburg for the past 45 years, staying committed to the community and watching the town grow over the decades. He chose to return to this region to be close to his roots and contribute to the health of the community he calls home.

In his professional career, Dr. Petras has served as a general dentist for over 40 years. He reached a major milestone in the late 1980s when he purchased his own dental practice and the building it is housed in. Since then, he has steadily grown the practice, modernizing equipment and expanding the team to support the needs of Amherstburg’s residents. Dr. Petras is well-known for his caring and happy nature. He uses his naturally positive personality to help nervous patients feel at ease during their visits. Because he has practiced in the same location for so long, he often treats several generations of the same families, maintaining a steady and honest approach to patient care.

Outside of the office, Dr. Petras focuses his time on his family. He and his wife raised their three sons in Amherstburg, and he views their success as his most important accomplishment. Today, his family has grown even further, and he is the proud grandfather of three girls. He stays active in his role as a grandfather and enjoys spending time with his grandchildren whenever possible. Having lived in the same community for 45 years, he has developed strong connections with his neighbors and fellow residents. He is known in the area as both a long-term professional and a dedicated family man. His life in Amherstburg represents a balance between a long-standing dental career and his cherished roles as a father and grandfather.
