Dentists in Harlingen

“Always good service and very friendly staff!
Thanks for helping me be healthy!!“

“I had a teeth cleaning appointment with my dental hygienist Elena, today. I now go every 3 months for cleanings due to some bone loss.

She is very gentle and has never made my mouth sore after a cleaning. This was the third one I have had since changing to Rio Vista Denistry back in November 2025. If you are searching for a dentist, I highly recommend this dental office.“

“Always nice to visit this office. Dr Guillén and staff treat you super and get you in and out with a smile. Office is always spotless and friendliest staff you will ever meet. Keep up the good work guys“

“Glad I found this place.. I'm treated like a person and not a number. Best part no long lines. No big crowds..My appointment was at 3:15 and I was seen at 3:15 not :45 min later like at the other place. I'm letting my friends and family about this place.“

“I’ve been going here for 3+ years and I’ve noticed a few things. When they are busy, they are very busy, don’t expect them to be able to pull more help out of thin air, if you walk in and it’s busy turn your patience on. Because the service and the actual quality of work that’s done here is amazing. I haven’t had to be referred to an oral surgeon or anything higher up, it’s been my basic treatments here for quite some time. They have great technology and very skilled doctor and assistants. I always love it when the results were less severe than originally forecasted because the doc has the skill to fix you up. So if you’re in a rush, ask for an appointment on a slower day upfront, please bring your patience and you’ll have a great experience.“

“I really like how all staff is friendly and make my children feel welcomed. The Hygienist Maria has been doing my daughters cleaning and they have yet to feel scared. She's very patient and works well with kids. Overall its always a nice experience coming in for appointments.“
