Where San Luis Obispo Smiles Begin and Thrive

Hear From Patients Just Like You

“Great customer service, friendly, knowledgeable, and professional office. Their office made changing dentists quick and painless. They requested all my records from my old dentist without me having to do a thing. I was able to get in for an appointment asap. I was able to fill out all new patient paperwork online and the text reminders are great. Dr. Colleran was great. Thank you Jean, Ashley, and Dr. Colleran for a wonderful experience!!!”

- Aliesha R.

“If you are a person who normally gets nervous when visiting the dentist, I highly recommend Michael Colleran DDS! From the moment you walk in, the staff is so nice and welcoming. It almost feels like you’ve already met before. Also the way that they explain everything thoroughly, makes it easy to understand. During my exam I felt relaxed and so comfortable which made the experience overall a good one!”

- Tanya T.

“I recently invested in the state of the art LANAP surgery to save my teeth and the process has been remarkably easy…The surgery itself was three hours long and I was able to drive myself home and carry on with my day without any difficulty at all...After the LANAP surgery, Dr. Colleran did a deep cleaning and then sealed my gum line with additional laser therapy to ensure that my gums were able to cleanly heal…Thank you so much to Dr. Colleran and staff for being one in a million!”

- Gwendolyn
