Hi there, my name is Mary Del Favero and I’m a passionate Realtor® whose main purpose in real estate is to help everyone I meet. There is nothing that brings me more joy than being able to successfully navigate my clients through their complex real estate journeys, no matter how long they take. I completely understand that the task of buying or selling a home is no simple task and certainly not an overnight decision, and that is the exact reason why I make sure I make this process as comfortable and stress free for my clients as possible. Buying or selling a home is often an emotional undertaking for my clients and this is probably one of my favorite things about my career. It means everything to me to be part of such an emotional time in my client’s lives and I love being there for them through every moment. One of the things I value most is my relationship with my clients and the trust they have in me. I love getting to know them throughout our journey together and it is always my goal to have them become my client for life. I take great pride in providing my clients with all their real estate needs. I hold a degree in Graphic Design and have extensive knowledge in marketing and photography and absolutely love getting to showcase these skills to my clients and enjoy using these skills to help them reach their goals. Some of my other passions include veganism, art, and volunteering with animal rescues & special needs students.
