Dr. Zachary Reicher

Hi Everyone!  I am Dolfield Dental’s new Associate General Dentist.  I just moved back to the area after a residency program at the Christiana Hospital in Wilmington, Delaware and am excited to be practicing in my hometown of Owings Mills.  I was born and raised in this neighborhood and even the tax free shopping of Delaware couldn’t keep me away.

After receiving my undergraduate degree in General Biology and Art Studio from the University of Maryland, College Park I earned my Doctorate of Dental Surgery from the University of Maryland, Baltimore.  All of this Maryland education has made me an avid Maryland sports fan…Go Terrapins!

My residency program has provided me with an enormous amount of training and experience in treating all aspects of general dentistry.  As an active member of the American Dental Association, Maryland State Dental Association and American Academy of Cosmetic Dentistry I am continuing to stay current on all the latest developments in dental care.

Outside of dentistry I enjoy reliving my days as an art major.  In the past I’ve taken classes at the Maryland Institute College of Art for jewelry and printmaking.  I am looking forward to getting back to my basement studio and can honestly say that “I can make you a work of art.”
