Dr. Fernandez graduated with Honors from the University of Florida (UF), where she received a Bachelor of Science in Zoology. While performing her undergraduate studies, she was a Florida Academic Scholar, President’s Academic Scholar, and Disney Scholar, and she was inducted to the Golden Key National Honor Society for outstanding scholarship and leadership. At UF she held the position of Volunteer Service Director for the Pre-professional Service Organization, where she coordinated more than 300 members to serve the community by organizing a variety of health-related volunteer opportunities.  She also received the Student leadership Award for her NIH (National Institute of Health) research and community service activities.

Dr. Fernandez went on to complete her Doctor of Dental Medicine from Harvard School of Dental Medicine.  During her time there, she conducted investigative studies in collaboration with the Pain Research Center at the Brigham and Women’s Hospital on evaluating the safety of using new dental local anesthetics for long acting purposes.  Dr. Fernandez was also actively involved in ASDA (the American Student Dental Association) at Harvard, where she participated in multiple community outreach programs such as Operation Mouthguard and Oral Cancer Screenings. She also served as ASDA Treasurer and as a Student Council member for her Harvard class.

Dr. Fernandez later moved to Puerto Rico to complete her specialty training at the University of Puerto Rico (ADA accredited), completing her Masters in Dental Sciences and a Certificate in Orthodontics. While at University of Puerto Rico, Dr. Fernandez continued to conduct and develop her investigative research skills.  Her weekly treatment of patients in the Craniofacial Cleft Lip and Palate clinic led to her interest in complex craniofacial abnormalities.  Her studies looked at the different types of craniosynostosis surgically treated at the University Pediatric Hospital. She evaluated their association with various potential risk factors, with the goal of heightening the awareness of the occurrence of those risk factors within the healthcare community.

Highly devoted to continually investing in her own education in order to provide patients with proven, successful results, Dr. Fernandez frequently attends lectures and conferences held by the American Association of Orthodontists, the American Dental Association, and the Northeastern Society of Orthodontists.   She takes pride in providing customized orthodontic treatment care to each and every patient.

Philip Falsetti, DDS

Born in Lewiston, New York, I grew-up in Niagara Falls and graduated in 1984 from Niagara Falls High School, where I was co-captain of the swim team. Later, I swam for Syracuse University. I’ve played bass guitar in a band along the way, and like tinkering with computers, radios, scanners, and other gadgets. I’m a proud owner of a Meade LX200 10″ SCT telescope, build mid-power rockets, and fly RC aircraft when weather permits. I have a beautiful wife and two fantastic children who gracefully tolerate my interests.

• Syracuse University, BA, Political Philosophy, ’88

My advanced training was based at The Buffalo General Hospital Dental Department, now part of the Kaleida Health Care System. There I sharpened my skills in the practice of general dentistry, including rounds in the Emergency Oral Surgery clinic, and Emergency Room on-call. Additionally, my residency included work at the  Deaconess Skilled Nursing Facility dental clinic, located in Buffalo, NY. All phases of general dentistry were provided, as well as treatment of geriatric and mentally-disabled patients.

I’ve also served the Tuscarora Native-American community as their dentist in the bustling Tuscarora Reservation Dental Clinic. This facility is located in the Tuscarora School complex, 2015 Mount Hope Road, Lewiston, NY. I have treated thousands of adults and children of all ages at this clinic, and continue to do so on a part-time basis.
