I have been coming to this office for about a year and a half. The staff are very welcoming and friendly. For cleanings they are very gentle on your teeth and gums. The office is nice and modern. They always offer you water and goodie bag at the end. Would recommend. Best dentist I’ve ever had!Kristen costa mesa ca dentist
