Dr. Stumpel is an amazing dentist. I had some awful dental experiences as a child. When I found out that Dr. Stumpel didn't use laughing gas, I almost immediately turned around and walked out. That was over 15 years ago. He takes his time explaining every process and procedure and is always makes sure I understand what is going on in my mouth. I still drive from northern Marin to his office. I refuse to go to anyone else!
