Summary

Mark A.
DeNigris, DDS
Following in his father’s
footsteps
“This practice was established by
my father, Dr. Guy DeNigris, back in 1954 and
was built on developing long-term relationships
with patients the old-fashioned, caring way. Like
my dad, I enjoy helping people achieve healthy
smiles, and my patients appreciate what I do.
I can’t think of anything else that I would
rather do for a living.”
DDS: Graduated
Head of Class, Georgetown University School
of Dentistry, 1980
BA: Catholic University, 1975

Advanced training makes the
difference
“In order to continue to improve
and stay current, dentists must constantly learn
about new advances in care. I have always sought
out the best continuing-education courses available,
preferably those that allow hands-on training.”
Advanced Training: Includes
hundreds of continuing-education hours in all
aspects of dentistry
Active in professional organizations
“Professional dental organizations keep
me informed of new developments in dentistry —
all of which benefits you as a patient. Plus,
I’ve had the opportunity to present and
share techniques and difficult cases with other
dentists.”
Member: American
Dental Association, Academy of General Dentistry
In his free time, Dr. DeNigris enjoys sailboat
racing, golfing, fishing and shooting.
