Dr. Gillian DeGennaro’s passion for dentistry began in the 5th grade, growing up in a close-knit town just outside of Cleveland, Ohio. From a young age, she knew she wanted to make a difference in people’s lives by helping them feel confident, healthy, and cared for—starting with their smiles.
A proud graduate of The Ohio State University, Dr. Gillian earned her degree in Health Sciences with a focus on Human Nutrition. She then completed her Doctor of Dental Medicine at Western University of Health Sciences in California, where she deepened her understanding of whole-body wellness and its powerful connection to oral health.
What truly sets Dr. Gillian apart is her heartfelt approach to patient care. She treats every patient like family—taking the time to listen, educate, and ensure each visit is a positive and empowering experience. By blending her knowledge of nutrition with advanced dental techniques, Dr. Gillian provides care that’s not only comprehensive but personalized to your unique needs and lifestyle.
Her goal? To help you feel calm, cared for, and confident—every time you walk through our doors.
When she’s not creating beautiful smiles, you can find Dr. Gillian enjoying quality time with her loved ones, discovering new restaurants, and soaking in Arizona’s natural beauty. She loves staying active and unwinding with peaceful evening walks.
Dr. Gillian is excited to welcome you to our dental family—and looks forward to being not just your dentist, but a lifelong partner in your health and happiness.
Dr. Gennaro is amazing! I came into S&C Dental Ranch for a cleaning and consultation, and she made the entire experience so comfortable. She took the time to explain everything clearly and gave me honest recommendations without any pressure. You can tell she genuinely cares about her patients and takes pride in her work. The whole team at S&C Ranch is super friendly, and the office itself feels modern, up to date and welcoming. Definitely my new go to dentist moving forward.
