“When my dentist retired, my wife recommended Dr. Bosak. After the exam, the doctor added several crowns and replaced a bridge. I then had the most intensive, amazing and thorough deep cleaning I have ever experienced. An excellent doctor and a wonderful staff.”
-Greg S. (a very happy senior citizen)


“My family has been seeing Dr. Bosak for about 10 years. Originally I was impressed because Dr. Bosak is “painless.” I’m 58, so I’ve been to a few dentists in my life. Dr. Bosak is the king of numbing, and it never hurts. Got a crown today and it was just so easy. Leeanne, our hygienist, is great also. But everyone in the office has always been helpful, professional, and skilled. They’ve gone the extra mile with insurance. I used to schlep far and wide to go to various dentists, but now our guy is right in Granada Hills where we live. Too bad all of the happy patients don’t take the time to review, only the cranky ones!”
