The office is clean, Suzanne is the most thorough hygienist (and super nice), Dr. K is easy to talk to and genuinely cares. I have referred my parents and friends to the practice and now my kids come here, too!

I’ve been going to this office and have been under Dr. Kreitzberg’s (Glen) care for decades. I’ve always felt I was in the very best hands. He is so skillful and knowledgeable, and really cares about his patients. His warm personality is special; he makes you feel like you’re part of his family. Everything is up to date and run very well. Can’t say enough good things about the office and the staff. I highly recommend going here - it doesn’t get any better!
