Our family has been having Dr. Ortega at Dental Cosmetix provide outstanding dental care for over 15 years. She is extremely generous with her time in making sure we get the best care and has even come in on the weekend to treat emergencies. We are always confident that we receive the highest quality care each and every visit. Dr. Ortega’s cheerful and uplifting attitude provides a positive atmosphere and makes our family feel comfortable as patients.

I am probably the wrong person to rate dental practice because I’m inherently biased! Yes, I love dental cleaning and scrapings! And, Dr Ortega is one the best! She and her caring staff are all so professional and friendly. Dr. Ortega listens to my concerns and never rushes me. I feel like I’m in good hands when I see her. If you have had the unfortunate experience of being with a “bad” dental practice then Dental Cosmetix is the right place for you!!!!
