What Our Patients Say

Carol’s Story

One of the things I love about [Dr. Amorteguy] is that she is always investigating the outer fringe of knowledge in dentistry but she works with us conservatively so that means that the conservative line is always moving forward because she always knows what is new and what is happening so she advances with that.


Ben’s Story

[Dr. Amorteguy] is very kind. She does not pressure you to do anything you do not want to do. She goes over everything with you before you do it so you are always making the most informed decision possible… I live 35 minutes away…and I do not regret that drive at all every time and I’m actually happy to come to the dentist’s office whenever I come to Dr. Amorteguy’s office.


Steven’s Story

My entire smile – front to back, lower – are completely new teeth [with veneers]. It has been wonderful. Teeth feel fine, look great, and nobody ever knows the difference so it’s a happy story.

Professional and very caring. Outstanding patient Interaction!


Dr. Amorteguy is top of the line and Karin the Hygienist will be a great replacement when Cathy retires. Dr. Amorteguy is the best dentist I have had in my lifetime!


Everyone was so friendly and helpful, and Dr. Amorteguy was awesome. She broke everything down in a way I could understand and was conservative with treatment. This was the best experience I’ve ever had at the dentist. I highly recommend Dr. Amorteguy and her awesome technicians and staff!

Hilary L.

I would recommend Dr. Amorteguy to my family and friends because everyone in the office is concerned and invested in my dental health. Also, I appreciate an aggressive preventative approach.


As always, this office is extremely professional and competent, even in a pandemic. Love that it's operated by an amazing female staff and my teeth are always treated with the uttermost care.

I'm very picky about who I let touch my teeth and I've lived all over - NYC, Paris, London, etc. - and this office is top notch.

Angela B.

Dr. Amorteguy is the apex of fine dentistry. I will and often do recommend her to family and friends.


Dr. Amorteguy and her staff are kind, efficient and very attentive to my needs.

I have had extensive dental work done by doctor and I can say with confidence she's the best dentist in San Luis Obispo and beyond!! All the things that matter to a patient are taken care of, everything is talked through and where there are options, they are laid out clearly for the patient to choose.

Dr. Amorteguy has truly been a lifesaver for me!
