St. Pete Oral Health Center

Fifteen years of trusted care, healthy smiles, and a commitment to the well-being of the St. Petersburg community


For Dr. Rosemarie Marquez, dentistry has never been just about teeth. It is about improving lives. After more than 34 years in the profession, she continues to approach every patient with the same passion that first inspired her career, combining clinical excellence with genuine compassion and a belief that oral health plays a vital role in overall wellness.
A graduate of the University of Florida College of Dentistry, Dr. Marquez credits her parents for instilling the work ethic and determination that shaped her career. Dentistry also gave her the flexibility to raise her family while pursuing the profession she loves. Today, she and her husband are proud parents of four children and grandparents to six grandchildren, a growing family that keeps life full of joy. She is equally grateful to have welcomed Dr. Malone to the practice, whose passion for compassionate patient care perfectly complements the practice's mission.
St. Pete Oral Health Center offers comprehensive dental care, from preventive services and routine maintenance to smile design and full mouth reconstruction. For more complex cases, the team collaborates with trusted specialists to ensure patients receive the highest standard of care every step of the way.
What truly sets the practice apart is its personalized approach. Every patient is treated as an individual, with time dedicated to understanding their goals, concerns, and overall health. Rather than providing one size fits all treatment, Dr. Marquez and Dr. Malone create customized care plans designed to support both oral and systemic health. Just as important, they believe in educating patients so they feel informed, confident, and empowered to make decisions about their care.
That commitment extends well beyond the office. For the past 15 years, Dr. Marquez has volunteered through Dental Lifeline Network, helping provide dental care to individuals who otherwise would not have access to treatment. The practice supports the Oral Cancer Foundation, fielding a top-fundraising walk team for its annual event, and offers free community oral cancer screenings every April for Oral Cancer Awareness Month.
This September marks an exciting milestone as St. Pete Oral Health Center celebrates its 15th anniversary. The team is also honored to have been voted Top Dentist in St. Pete and named the second favorite Cosmetic Dentist in St. Pete Life's Readers' Choice Awards. Looking ahead, the practice is expanding and remodeling its office, complete with Dr. Marquez's signature touch of purple, to accommodate continued growth and allow even more patients to benefit from the exceptional care provided by Drs. Marquez & Malone and the entire team.
