Meet the Team
Dr. Stefhany Duque, DMD

Dr. Stefhany Duque is the new owner and dentist at Holehouse Center for Complete Dentistry in Winter Garden. She is honored to carry forward the legacy of care Dr. Thomas Holehouse built over many years, and in the coming months the practice will begin its next chapter under a new name, Lifelong Dental. The name is new, but the familiar team, the same location, and the personal care you know will stay the same.
Dr. Duque brings eight years of clinical experience caring for patients across Central Florida. She graduated summa cum laude with a Bachelor of Science in Biology from Florida Gulf Coast University and earned her Doctor of Dental Medicine (DMD) from the University of Florida College of Dentistry.
She believes great dentistry depends on never stopping learning. Since graduating, she has completed extensive continuing education with some of the most respected programs in the field, including The Dawson Academy, the Kois Center, and Spear Education, where she focused on comprehensive diagnosis, bite and jaw function, and long-lasting restorative care. She has trained with CEREC Doctors in same-day digital dentistry, completed advanced implant training, and is a certified Invisalign and Candid provider.
Her philosophy is simple: understand the why before deciding the what. Every treatment plan starts with a thorough exam and a clear conversation, so patients understand their options and can make decisions with confidence. Her work includes same-day CEREC crowns, dental implants, which she places herself, clear aligner therapy, and complete smile makeovers with veneers, crowns, and bridges.
Dr. Duque is bilingual and happy to see patients in English or Spanish. Outside the office, she lives in Winter Garden with her husband, Mark, and their labradoodle, Ollie. She loves to travel and brings home a small keepsake from every country she visits.
Dr. Mark Zavala, DMD
Dr. Zavala has completed extensive advanced education beyond dental school, with a special emphasis on implant dentistry. Having him on our team means many patients who need more complex care can receive it right here, in an office they already know and trust, instead of being referred elsewhere. He takes the time to walk patients through each step, so they feel informed and comfortable before, during, and after their procedure.
He completed his undergraduate studies at the University of Miami and earned his Doctor of Dental Medicine (DMD) from the University of Florida College of Dentistry, graduating in the top ten of his class. Dr. Zavala is bilingual and happy to care for patients in English or Spanish. He is also the husband of our owner, Dr. Stefhany Duque.
