Their expertise, caring nature, and passion for high-quality dentistry makes them stand out from the rest in McAllen. If you’d like to meet them before your next visit, take a look at their brief bios ahead of time. They can’t wait to meet you and start providing your family care!

Diane Tijerina, Registered Dental Hygienist

A McAllen native, Diane completed her Bachelor of Dental Hygiene at Baylor College of Dentistry. She also has a Bachelor of Arts in English Literate from Pan American University. Today, her career in dentistry spans over three full decades! She loves having the wonderful opportunity to share her dental hygiene skills and heart with each lovely patient, as well as working alongside such a talented staff.

Diane’s family consists of her spouse Justice Jamie Tijerina, her daughter Katie, and her beautiful toddler grandson Dominic. She also has a Terrier mix named Benny and two Lady Gouldian Finches. In her free time she enjoys golfing, walking/jogging, reading, hiking, cooking, playing games, spending time on the beach, and traveling just about anywhere with her husband. She’s also an avid amateur bird watcher.

Frances Delarosa, Patient Care Coordinator

Frances’ career in dentistry spans over two full decades so far, and she’s built countless meaningful relationships with our patients throughout the years. She studied at South Texas College and RGV Careers; she is a Licensed Vocational Nurse in addition to her oral healthcare expertise. She had horribly crooked teeth when she was younger and wore braces twice, which sparked her initial interest in this field. Today, she’s still looking to truly perfect her smile!

Frances is married to her high school sweetheart Jason, and they have two young adult children. Outside of the dental office, she works as a part-time nurse and enjoys running/walking in local 5k’s.

Stephanie has been working in dentistry for over seven years now, with most of that time spent right here. She is currently studying at South Texas College and is a Certified Nurse Assistant.

Stephanie was raised by her mother and has a younger sister named Kimberly who lives in Austin. She is also a proud Dog Mom to her Chihuahua Nayla. With two jobs AND college classes on her plate, naps are absolutely essential at the moment! She also enjoys working out at the gym, reading, listening to inspirational podcasts, and going out/traveling with friends.
