Meet Our Doctors

Dr. Stephane Lefebvre

Dr. Stephane Lefebvre’s interest in dentistry began at a young age due in part to an excellent relationship with his own family dentist, Dr. Ken Clark, who would later become a mentor and colleague in the dental profession.

Stephane’s curiosity and eagerness to learn about oral health and the dental profession materialized into a high school science fair project titled “Plaque Attack: The science behind tooth decay,” for which he won a “Best of Fair” award at the Lambton County Science Fair. Stephane then represented Lambton County at the Canada Wide Science Fair.

This early experience motivated Stephane to pursue dentistry as a profession. He gained admission into Western University’s School of Dentistry in London, Ontario. Six years after graduating from St. Patrick High School in Sarnia, Dr. Stephane Lefebvre returned home with a Doctor of Dental Surgery degree. He began practicing dentistry in the building where his dream began, with Dr. Ken Clark.

Dr. Lefebvre has been practicing dentistry since 2003. He holds numerous association memberships and is a past president of the Lambton County Dental Society.

His wife, Nashlea Brogan, Doctor of Audiology, is a private practice audiologist in Sarnia. She is the founder and president of Bluewater Hearing. They have two young children and enjoy all that Lambton County has to offer.

Dr. Kelly Vosburg

Dr. Kelly Vosburg was born and raised in Sarnia, Ontario. She was a student at Northern High School prior to completing her Bachelor of Science from the University of Western Ontario. After graduation, Kelly attended Semmelweis University, where she received her Doctor of Medical Dentistry (DMD). During her time at Semmelweis, Kelly was involved with the student council, where she held the spot of class president.

While completing her education, Kelly worked for the Canadian Coast Guard doing search and rescue and continues to volunteer with the local auxiliary. Dr. Vosburg is excited to return home and work alongside one of her mentors, Dr. Lefebvre.
