Melissa was truly wonderful to work with. She was always on the ball and super professional. Her relationship building with other agents was a huge asset as we went through selling our condo and buying a house - we always felt like we were in great hands with Melissa. She was patient, honest, and understanding as we took our timing finding the perfect house, never giving up hope on us or making us feel rushed or pressured to put in offers above our level of comfort! We trusted her opinions on the houses we looked at and in the end, successfully sold our condo in a very difficult market and bought a house that we're very happy with! So much of working with a real estate agent is about trust, and I can honestly recommend Melissa if you're looking for someone trustworthy and reliable.

Melissa is such a great agent, she actively listens, follows up and makes sure that your needs are met, She does not impose her idea rather gives her advice, take you through the process and information the client needs and gives the client room to decide. It was great working with Melissa. I would recommend her anytime any day. She did go above and beyond to make sure our rental experience was smooth.

Melissa has been such an amazing person to help guide us through this entire process. She was so patient, supportive, understanding, and knowledgeable. I couldn’t imagine any other realtor to work with ! I recommend her to everyone because she is so good. Even when we were a bit frustrated and down from the market prices being out of our budget, Melissa Encouraged us and knew there was a house meant for us. Now we live in our wonderful home! we wouldn’t have been able to do it without her!
