About us

A Commitment to Excellence

Dr Slepski’s passion for dentistry began in dental school at Loma Linda. He takes pride in improving his patients oral health and appearance while keeping his patients as comfortable as possible. Dr. Slepski will also spend the extra time to educate patients so they better understand their oral health and know what’s going on with their teeth. State of the art digital x-rays and intraoral cameras make it easy for patients to see and understand their needs. Preventative care is a major emphasis, but will gladly help those who may have neglected their teeth or who have not seen a dentist in years.

We are here to serve you

Dr. Slepskis staff treat each and every patient with gentle care, as they would themselves. Patients who may be nervous are also given the option of sedation for their convenience. Oral sedation, Nitrous Oxide (also known as laughing gas) and I.V. “twilight sleep” are three of the options available to our patients in order to make treatments as comfortable as possible.
