Happy Stories

Amazing dentist and staff.  Dr. Soriano has been my Dentist for 20 plus years. I had always been an anxious and very fearful patient until I met Dr. Soriano.  Last September I made an appointment with him  only to find out that he had moved on.  I was relentless trying to find him, the staff said they were never told where he went. 


The entire Cassidy Smiles crew is outstanding. Their customer service is above and beyond. Q, the hygienist, is so gentle and so knowledgeable about so much more than dentistry. While he does his thing,


A few weekends ago I broke my front tooth inadvertently biting into a plastic fork while attending a birthday celebration. My front teeth had been previously crowned many years ago.
