John E. Sullivan, D.D.S.

Dr. Sullivan, an Oak Park native, earned his biology degree from Loyola University Chicago in 1979 and his Doctor of Dental Surgery from the University of Illinois Chicago College of Dentistry in 1983. After honing his skills for several years in practices on North Michigan Avenue and Chicago’s Near South Side, he opened his own office in 1987 alongside his high-school friend, Dr. Larry Humberstone, DC. By 1998, growing demand prompted a move to the current location at 511 Thornhill Dr., Suite H, Carol Stream, IL—where he continues to welcome patients today.

Over more than four decades, Dr. Sullivan has amassed 3,300+ hours of advanced continuing education in craniofacial pain, TMJ science, prosthodontics, implant dentistry, IV sedation, orthodontics, and oral surgery. His relentless pursuit of knowledge ensures every patient receives the most up-to-date, comprehensive care possible.

Outside the office, Dr. Sullivan enjoys golfing with his wife and sons, tending a prolific backyard garden, and sharing its bounty. If you visit during the summer, don’t be surprised to find fresh fruits and vegetables in the waiting room—just one more way he brings a personal touch to the practice.
