About Mary

Experienced agents are a great resource to buyers and sellers for saving time and money and making a big move, relatively stress free.
Marketing is what I am trained to do with a bachelor's degree from St. Joseph's University and the following designations: CRS, GRI, CDPE, RPR and ePRO as well as completing a graduate program on integrated Social Media Marketing to give my clients the edge they need to sell their houses faster and for more. Over 90% of my business comes from repeat clients or personal referrals, so I treat all of my clients like gold. Referrals are what I love best so I work really hard to make sure that my clients want to refer me to their special family & friends when they complete their transaction with me.
Many of my clients have used my services 3 or 4 times and are now referring their children to me to help them buy their first homes.
I love my job and I hope it shows!
