Wow, so grateful to have gone through one of the biggest decisions of our lives with Mary-Jean. We are first time co-op shareholders and Mary-Jean made the process so much less stressful and was so personable during every step of the way. She was kind and attentive and sent us so many recommendations from lawyers, to floor refinishers, to painters to use once we finally got our keys. We took her advice on everything and couldn’t be happier. I’m so glad I can look back at what could’ve been an extremely stressful experience and feel happy that I had Mary-Jean in our corner. Thank you for everything, Mary-Jean!

Mary-Jean is a top-notch NYC realtor and my go-to professional in the city! She recently referred a seller client to me in Westchester, and her professionalism, expertise, and seamless communication made the entire process a dream. If you're looking for a dedicated and accomplished realtor in NYC, I highly recommend Mary-Jean!
