The history of Dr's Roschella & Zinger

Dr. Karen Roschella and Dr. Ann Zinger opened their first practice in the Enchanted Forest shopping center in Ellicott City in 1993.  Over 14 years their practice grew and they eventually were out of room!  It was time for a change.  They expanded and moved locations in 2007.  In addition to gaining more space, the dental practice was able to incorporate the most advanced and efficient equipment.  Every detail of the new office was researched and planned to provide the best dental care possible for their patients.   We are so proud of our team and office. Roschella & Zinger Dental Group is now located in Waverly Woods, come and visit!  Let us change the way you feel about going to the dentist!
