Dr. Sonja Sproul
Dr. Sonja Sproul became passionate about dentistry at a young age while assisting her father, Dr. William B. Sproul, on a dental mission trip to Belize. Her interest in dentistry grew throughout college when she had the opportunity to travel to Africa as a dental assistant.
Today, Dr. Sproul is pleased to step into her father’s footsteps, taking over the family practice to provide great dental care in Eugene. Patients often comment on Dr. Sproul’s gentle touch, calm demeanor, and inviting approach. Behind the scenes, Dr. Sproul is committed to staying up to date with the latest dental techniques and technologies to provide the highest-quality service possible.
“One of the most rewarding aspects of being a dentist is that I get to build long-term relationships with my patients and their families while offering high-quality, personalized dental care.”
