What Kirkland families say
"The best! Everyone is super friendly and professional and they take great care of their patients. "
"Really excellent routine cleanings and care and they always offer me good recommendations for oral care products. I am grateful they are in my neighborhood and I highly recommend this practice!! "
"Was in the area and had a crown fall off. They got me in quick and got the new crown put on the same day! Super friendly with them. They are very, very thorough and knowledgeable. This might seem like a small thing, but the music they play in the office is wonderful. Nice 80s retro!!!"
"Dr. Beetham and the entire team are highly competent and professional, as well as kind, caring, and gentle. Further and equally satisfying is their amazing connection to medical e-management of my personal data! Very impressive all around!! "
"Marianna Beetham is the best dentist I know. She's knowledgeable and considering. I cannot recommend her more. "
