Frinet Kasper, DDS

Dentist in Old Town Alexandria, VA


Dr. Frinet Kasper is honored to provide outstanding dental care right here in Alexandria, Virginia. Her love for restoring smiles began in high school when she had the opportunity to shadow a dentist. Observing the unique doctor-patient interaction and the doctor’s ability to empower confidence with a healthy smile, she knew she wanted to help others as a dentist.

Dr. Kasper strives to be a positive difference in the lives of her patients with high-quality, personalized dentistry. To her, it is important to establish a good relationship with her patients in order to better understand their dental goals and what is preventing them from reaching those goals. Educating her patients has always been her number one priority.


Dr. Kasper graduated from Dental School in 1994. After years with a private practice, she chose to further her education and skills. She completed a General Practice Residency at Western Reserve Care System, a major teaching hospital of the Northeastern Ohio University College of Medicine. Having completed her advanced education, she returned to Northern Virginia to continue to provide her caring values. 

Today, she continues to enhance her dental knowledge with a variety of professional education courses on specialties like Invisalign (invisible braces), cosmetic and restorative procedures, implant restorations, digital dentistry, and more.
