Awesome dental team!Posted on Google Mike TangTrustindex verifies that the original source of the review is Google. Dr. Koeltl and his staff are friendly, so caring and provide excellent care for my teeth. Recently Dr. Koeltl kept pursuing dryness in my mouth during sleep (potential gum disease) and provided me with options to fix it. A simple piece of tape to keep my mouth shut during sleep fixed the problem. My hygienist does a great job each visit cleaning my teeth.Posted on Google Olivia LevineTrustindex verifies that the original source of the review is Google.
