We have done 10 real estate transactions with Mari-Cris O’Neill of McClellan Sotheby’s International Realty.  Over the course of a 20 plus year relationship we have found her to be a realtor of extraordinary integrity, diligence and reliability.  She has assisted us in situations where she has always put our needs ahead of hers.  We would never hesitate to recommend her to anyone.  The Williams Family

Mari-Cris is a true partner in the quest for the best home for you and your family.  She listens acutely to what you are looking for in a home and shows you only properties that match always providing an overlay of color/informed context for consideration.  She is thoughtful, kind, patient and highly knowledgeable on all things Pelham and lower Westchester.  Anyone would benefit greatly from her expertise and be lucky to work with her in their search.  Jeremy and Maia

We loved working with Mari-Cris and her team at McClellan Sotheby’s International Realty.  Mari-Cris was patient with us and we could tell that she cared about making sure we found the right home for our family.  She became fluent in our likes and dislikes and showed us houses that fit the unique qualities we were looking for, eventually finding us a perfect match.  And then she stayed on top of everything from signing to closing, making sure the deal got done on time and to our extreme satisfaction.  Mari-Cris is a wonderful broker and we won’t hesitate to refer her to our friends in the future.  Yonaton and Emily.
