2013 Angie's List Super Service Award Recipients for 2nd Year in a Row

Frederick Maryland Dentist AwardPearlfection Dentistry – Frederick Maryland – Dr EJ Stringer and Dr Joseph Mullen,  is pleased to announce their acceptance, for the second year in a row, of the prestigious Angies’ List Super Service Award.  This honor is given to recognize the top 5% of qualifying businesses per category, in each market, who maintain superior service ratings and reviews throughout the past year.  Dr Mullen and Stringer where the only dentist to receive this award in Frederick MD for both 2012 and 2013.

When asked for comment, Dr Stringer attributed the success of the practice to great patients, who are a pleasure to work with, a team that is dedicated to the happiness and health of our patients, cutting edge technology that allows us to diagnosis and treat dental problems. Dr Stringer said “When the entire team works together, it shows, and patients appreciate the superior level of care they get here.  We truly care about our patients.”

Dr Stringer and Mullen are on call 24/7 365.  They understand that sometimes patients need care when the office is closed.  Sometimes that care can be handled over the phone but sometimes the doctors actually have to open the practice up in off hours.  That’s the type of service that allows the practice to grow and prosper.

Business Manager Stewart Stringer said “while some dental offices are struggling, we are adding staff members (7 so far in 2013), investing in equipment and looking for property to expand.  We have extended our hours and added another operatory and hired a root canal specialist.  When it comes to a good dentist, word of mouth is really important.  Dr Mullen and Dr Stringer have a great reputation in Frederick. We provide superior dentistry and we try to keep our prices reasonable.  That has made us successful over the years.  Patients like our practice and feel comfortable there and they tell their friends.”
