Meet Dr. James Warren

He earned his Doctor of Dental Surgery degree from the University of the Pacific Arthur A.

He believes in taking the time to explain findings clearly and offering recommendations that support long-term oral health. Whether it’s preventive care, restorative treatment, Invisalign, implant placement and restoration, or oral surgery, his goal is always to help patients make decisions that feel right for them.
Dr. Warren is committed to making each visit a positive and transparent experience. He ensures every patient’s concerns are addressed and that they clearly understand their condition, their options, and what to expect next.

John S.
Dr. Warren continues to demonstrate excellent service and care. I called his office on a Friday with an urgent concern (the office is closed Friday)Dr. Warren returned my call the same day, reviewed my dental history, determined my concern was not necessarily an emergency and scheduled an appointment for me the following Monday. He then took an X-ray and discussed my treatment options with me. I'm grateful for Dr. Warren'scommitment to my dental care.

Best dental experience ever! My husband insisted I try his dentist after years of not being happy with mine. My last dentist made me feel like a cash cow where all he wanted to do was push services that I didn't need. He even got upset when I didn't like his assessment of braces and I sought a resolution on my own and straightened my teeth affordably without him. Anyway, fast forward. I went to James Warren Dental and the entire staff was so welcoming and kind. We had a great conversation, and they were very accommodating. The office is beautiful and clean. Dr. Warren is also very kind and thorough. I felt comfortable and assured that they had my best interests at heart. I'm very grateful and will be going to James WarrenDental from now on!
