Hattie and Dr. Ona at the practice front desk

General dentist & owner

Dr. Suzzette Lirio Ona, DMD

Dr. Ona founded Healthy Smile so that patients, especially women and children, would feel at home: “I want patients to feel as though they are visiting family and close friends, taking away the fear of dentistry and building trust with each appointment.”

Dr. Ona received her B.A. in Biochemistry from Mount Holyoke College in 1989 and worked as a biochemist until 1994. In 1998, she graduated Magna Cum Laude from Harvard School of Dental Medicine with her Doctor of Medicine in Dentistry. She completed her residency at the University of Washington Hospital, treating adults and children with disabilities in operating-room and emergency settings. She is a member of the American and Michigan Dental Associations.

Dr. Ona believes in providing the best care for each patient. With over 25 years in dentistry, she has worked hard to learn modern procedures from all over the United States and applies them to Grand Rapids and surrounding communities. From implants to Invisalign to in-office teeth whitening, her patients are informed of all their options. Each visit starts with "What brings you in today? How can we help?" - and the answer includes a discussion of all modern dental options. Without pressure or judgement, her patients choose the best dental procedure that fits their belief, budget, and time. She teaches her patients how to phase dental work so it's affordable, and how to maintain their health investment. Procedures like implants and bone grafts are available to her patients, wherein other places, these dental options may not be considered or accessible. Dr. Ona has worked with the best dental specialists in Grand Rapids for the last 25 years. She believes in offering EVERYONE the best dental care she and her team can provide.

Away from the office, Dr. Ona enjoys time with her husband and visiting her daughter’s family, especially her grandbabies.
