“The office had plenty of parking, was clean and welcoming. The staff was very friendly, told me the plan for the day, Dr Espinoza was very thorough in showing me my X-rays and his suggestions for treatment, he addressed all my concerns and goals and made reasonable recommendations, the office staff had a estimate for all the treatments I was interested in doing and my costs after the insurance covered their part and offered to break it up into a few appointments, and we set the appointments up before I left. Fantastic service, I’m glad I found this office! ”

“I had a positive experience in every aspect of my visit, from front desk, xrays, and exam. Dr. Espinoza was thorough with his exam and responsive to any questions I had. He is polite and respectful unlike other dentists that I've seen. I saw him once a year ago when he fixed a bad crown put in by another dentist, after that visit I knew I would be coming back to be a forever patient. ”

At a new patient appointment, Dr. Espinoza had studied my (fresh, taken at the appointment) x-rays in detail, was friendly but professional, listened to and discussed in detail my current dental care protocol and suggested some quite reasonable modifications, and left me feeling I was in good hands. I could have wished for a shorter wait between x-rays and the meeting with Dr. Espinoza, but (as noted) he took time to review my x-rays in advance. Booking my next appointments was straightforward, and the treatment plan for a crown replacement was clearly explained. There were some upgrades in the treatment plan that I might have questioned, but I appreciate that Delta PPO dentists may sometimes need to upsell a bit to compensate for Delta's rather minimal rates, and the upgrades were reasonably priced.

I was nervously needing to select a new dentist. I researched many dentist profiles and reviews and Dr. Espinosa stood out. I was able to get an appointment about a week out. I had communication with the office staff who were so friendly and helpful. Arriving at my appointment late because I was at the wrong office building. Again contacting the office explaining my tardiness, Sophia was so sweet, providing details of the appearance of the building. Final arriving at the right building feeling humbled by my mistake, I completed the paperwork and got right in. Becca took me to the room and got the details for my visit. Dr. Espinoza came in and did his dentist thing. After a thorough exam and reviewing the x-rays he explained the proposed treatment plan in a comprehensive way I could understand. I was completely comfortable with the plan and the selection of my new dentist. I am so glad to find a caring dentist that I am completely comfortable with.

I’m visiting the area and it was very easy and straightforward to book an appointment, I knew my up front costs before I got in the chair.
October 31, 2025Scott B.Verified patient
I had a good experience overall. I was honestly kind of shocked at how much whiter my teeth looked after my cleaning. I was treated kindly, and overheard the dentist explaining some very in depth issues with another patient. Seemed like a good dentist from what I overheard. My appointment was very straightforward, so I spent most of my time with the hygienist. She was kind and thorough (Marguerite). Good listener.
