What Clients Are Saying

Susan was great so helpful in buying my first home. Also the best realtor I had. She was always available at anytime to take my calls. Susan made everything so easy and simple for us. I would definitely recommend her to anyone.



Susan asked the right questions to find out how to help us find the right property. She went above and beyond to provide us with information needed to make a good decision and get the right fit for our needs. We are happy with our purchase and appreciate her help. We would do it all over again.



Highly recommend! Always available for any questions or help, willing to help to find the right home! We really appreciate all your help during our process to find our home! Thanks Susan!!



My wife and I purchased a house in PA, coming from WI. After spending two days viewing properties with us we put an offer on a house. After inspections this deal fell through, but Susan continued to view houses with us on Zoom so that we could view properties without having to come out to PA again. It was reassuring for us to know we had someone on the ground in PA to view houses so that we weren't buying alone after only viewing properties using online resources. Susan was also a vital resource during the municipal inspection process for us as we were unable to occupy the property we had purchased (owing to an uncommon municipal inspection). Susan worked to resolve the issues we had with the municipality and get us into our house.
