Our Doctor

Diana Do Mayo, DDS

Dr. Diana proudly hails from the state of Texas, where she was born and raised in the DFW area. With a deep appreciation for the South's green pastures and welcoming neighbors, it's no wonder she eventually made Tennessee her home!

After embarking on a decade-long journey of formal education to obtaining her doctorate, Dr. Diana and her husband found their paradise in the beautiful Islands of the Pacific Ocean, specifically in Kailua Kona, Hawai'i. There, they embraced the close-knit community of Hawai'i, where she discovered her passion for surfing, hiking, diving, and all things adventurous. After several thrilling years of serving their community, they decided to trade their surfboards for guitars, and relocate to Middle Tennessee, where they found a caring community and decided to start a family.

Dr. Diana is proud to serve Middle Tennessee as one of the leading Board-Certified specialists in Pediatric Dentistry. As a proud alumnus of the prestigious Yale University School of Medicine, she further honed her skills as a resident doctor of the Yale New Haven Hospital in Connecticut. With a strong foundation of knowledge and experience, Dr. Diana ensures that every patient receives top-notch care in a welcoming environment. Her joy for working alongside families and kids shines through her work, making her a trusted choice for families in the charming communities of Robertson County.

When not in the office, Dr. Diana enjoys spending quality time with her husband, their lively & spirited "twiblings", and their beloved dog Junie B. Her journey to parenthood is a unique and fun story, and raising two toddlers just three months apart has become the heartbeat of her heart and soul! Next time you're in the office, keep an eye out—you're likely to encounter these two adorable little ones, so feel free to say hello!
