    Dr. Pete (and Dana) are by far the most caring, patient dentist (and assistant) I’ve ever had. He caters to cowards (like me). But the best thing about Dr. Pete is that he won’t stop until YOU are happy! What more could one ask for? He’s my all time favorite. ?

    Dr. Pete and his staff are the best! I used to be afraid to go to the dentist, and I no longer am. I would highly recommend Mertz Family Dentistry to anyone. They take such good care of me.

    I’ve been going to Mertz Family Dentistry since the days of Guy Mertz, long time! Now Dr. Pete has the business and carries on in grand fashion. Two fond memories, when the office was down on Terry Street, I took my Dad to see Dr. Pete and he was so kind and gentle with my Dad. I’ll always remember that and this was more than 20 years ago. Then there’s Amber, now retired and I loved her kind and gentle soul. I miss Amber, but Mai is amazing as well. Love Dana too! Great place??????
