Why patients choose Trillium

Patients in Westlake Village and nearby communities choose our team for OB/GYN care, primary care, weight management, and health maintenance. We welcome people from every walk of life and make time to understand their concerns.

Many patients transfer to our practice because they have been treated like a number in other offices. Trillium Medical has the philosophy that every patient is important and that every patient deserves our attention and respect.

Friends for life

We love our patients. We consider everyone who enters the doors of our practice to be a friend for life. We enjoy seeing them at The Oaks Mall, at Sprouts grocery store, and at local sporting events. There is no greater honor than the trust bestowed upon us by new patients.

Dr. Troy Williams is the OB/GYN whom many others in the community trust and depend on for assistance.

Dr. Williams feels that his career as a physician is his vocation in life. Every miracle that occurs and every life saved is a part of God's plan. That principle guides every decision we make.
