Dr. Kristina Visic, DDS


Dr. Visic was born and raised in Rochester, New York. She received her
undergraduate degree from Syracuse University, a Masters of Medical Science
from Hampton University and her Doctor of Dental Surgery degree from the
University of Maryland Dental School. For advanced training, she completed
a General Practice Residency at Erie County Medical Center in Buffalo, NY.

Dr. Visic’s goal is to make patients comfortable not only as they receive
dental care but also to understand its importance. The mouth is a gateway
to the rest of the body where oral health can influence systemic diseases
and vice-versa. She values each patient as a unique individual with
different goals and needs, not a “one size fits all” approach.

When not practicing dentistry, she enjoys exercising, spending time with
family (especially her two adorable nieces) and friends, reading, watching
documentaries and listening to music. Living a healthy lifestyle and
learning is of utmost importance to her and she incorporates it in all
aspects of life. She is excited to be part of the GFDI Family!

Dr. Kyle Kenyon, DMD


Dr. Kenyon is originally from Kennett Square, Pennsylvania, roughly 40 miles west of Philadelphia. He completed his undergraduate education at The Pennsylvania State University and received his Doctor of Medicine in Dentistry (DMD) degree at the Maurice H. Kornberg School of Dentistry at Temple University. In pursuit of advanced training and education, he also completed a General Practice Residency at the Eastman Institute for Oral Health at the University of Rochester.

One of the main reasons that Dr. Kenyon got into the field of dentistry was the positive impact a dentist can make on a person’s life. Whether it is due to difficulties eating, speaking, or even a lack of self-confidence when smiling, a dentist is able to improve these aspects of oral health and in turn improve a patient’s daily life. During this journey between dentist and patient, a lifelong relationship is formed that Dr. Kenyon really cherishes.

Outside of his passion for dentistry, Dr. Kenyon really enjoys being outdoors no matter the season. Hiking, golfing, skiing, boating, biking and playing tennis are some of his favorite outdoor activities while he does occasionally love relaxing on the couch watching sports or lounging in a hammock with a good book. Dr. Kenyon takes pride in being a good cook (who is always open to new recipe suggestions!) and is a dog dad to Riley, his 5 year old black lab.

Dr. Sierra DeMarree, DMD


Dr. DeMarree is practically local as she is originally from Sodus, NY . She completed her undergraduate education in 3 years at the University at Albany, which is where she met her husband Rein. Dr DeMarree received her Doctor of Medicine in Dentistry (DMD) degree at the Henry M. Goldman School of Dental Medicine at Boston University and continued to complete a General Practice Residency at the Eastman Institute for Oral Health at the University of Rochester.

Dr. DeMarree has been aware of her desire to become a dentist since she was 9 years old. She broke her front teeth on the pool deck at a girl scout lock-in and has spent her whole life in the pursuit of giving patients a sense of relief from discomfort while improving their smiles. Since, who knows, they may be inspired to become a dentist just like herself! 

Outside of dentistry, Dr. DeMarree loves to spend her time doing outdoor hobbies. She is an avid archer and huntress, a fisherwoman, a hiker and a camper. Her favorite hobby is rock climbing and you can always find her after work at one of the indoor rock climbing gyms here in Rochester! Not only does she love the mountains and the woods, she grew up right on the shores of Lake Ontario and loves swimming and boating and collects beach glass and seashells. She also can be found at local music venues supporting her husband’s band. Dr. DeMarree also has a Beagle-Blue Heeler rescue puppy named Rosie, who loves to keep her on her toes!
