Jeffrey T. Bonk, DDS

Dr. Jeffrey T. Bonk has been transforming smiles in Barrington for more than 35 years. His commitment to dental health and his passion for education are the heartbeat of our practice.

He graduated from the Loyola School of Dentistry in 1981 and immediately enrolled in a graduate residency program at Loyola Hospital where he gained advanced training in oral surgery, periodontics and prosthodontics. In 1982 he opened our Barrington practice, joined the medical staff at Good Shepherd Hospital and has never looked back!

Dr. Bonk believes that continuing education is paramount for success. He routinely attends high-level educational conferences around the world learning from the world’s foremost dentistry experts. He also shares his knowledge and expertise by mentoring younger dentists. In fact, he’s been recognized nationally for his mentoring and teaching.

While much of his time and energy is spent focused on his patients and his practice, he enjoys biking, hiking, golfing and cooking in his spare time. He and his wife, Christine, love to travel and spend time with their five children and seven grandchildren.
