"Heather and Mary are great to work with. We used them both to sell and buy a house. Could not be happier with their professionalism. In addition they are both lovely people."


"Mary and Heather did an amazing job helping my brothers and I sell our parents’ house. They are very knowledgeable about the market and small businesses in the area who helped us clear out the house and get it ready to go on the market. You couldn’t ask for two nicer people to sell your home."

"Heather Kaznoski and Mary Stewart are a team of aces. They were thorough, considerate, and persistent in helping us sell and purchase property. We counted on Heather and Mary for their expert guidance and advice, as well as for their tenacity in finding the right properties and helping us negotiate on purchase agreements. When it came to selling our house, they lead us down a quick and successful path. They were perfectionists who thought of everything. All we had to do was follow their lead and we were winners. We highly recommend the dynamic duo of Mary Stewart and Heather Kaznoski."


"I have had several experiences working with Heather and Mary. They have always provided valuable advice and go beyond what is normally expected in a broker/client situation. Their knowledge of the current market and long experience in real estate was invaluable to me."

"Mary and Heather were incredibly patient, supportive, and responsive with us during our home search in Marblehead. They were knowledgeable about the market and offered us valued advice. They were thorough and followed up consistently. We felt well taken care of and we would fully recommend them to anyone looking to buy or sell a home!"

“Real Estate brokers, Mary Stewart and Heather Stewart Kaznoski are extremely professional on all counts. Somehow, all the parties involved in a sale are kept on track. Never in 35 years have we encountered a loose end in any transaction. Their advice, always dispensed delicately, is worthy of your careful consideration. They know their business. A big advantage is their keen understanding of architecture, construction, building materials, building codes and design. Every house is looked at, not only for what it is, but what it could, or could not, be. You may find yourself "seeing " a home in ways you had never considered. In short, Mary and Heather can be counted on to be the best, you couldn't ask for a better team to guide you through your next critical investment, be it buying or selling a home.”

“My experience with Mary Stewart and Heather Kaznoski was excellent. They handled the sale of our Marblehead home with professionalism, respect, and went beyond expectations. Appreciated the recommendations they gave to freshen up the home without spending money frivolously. They communicated very well, were thoughtful, and respectful of my time. The attention to even the smallest detail was superb. Would highly recommend this real estate team!”

Tanya G.

“We worked with Heather Kaznoski / Mary Stewart for a little bit more than 2 years selling our business condo. It was not the best time for Real Estate Market, but Mary & Heather worked diligently on advertising and promoting our property. They gave us very valuable advises on what was supposed to be improved with our space, utilities, and surrounding grounds to attract new prospective buyers. They constantly kept in touch with us and updated us with Real Estate Market news and changes in our area. Finally, we sold the property exactly at asking price, thanks to Heather and Mary. We give them 5 stars for their outstanding professional job and recommend these amazing R.E. team to everyone.”

Matt H. and Tova K.

“Our experience with Heather & Mary was absolutely wonderful. We used them to purchase two of our homes in Marblehead and to sell one of them. They truly have a solid understanding of the market and their experience and expertise proved to be an invaluable resource to us. I would absolutely recommend them to anyone looking for a realtor who will also be a partner and who will provide honest and helpful insight.”

Jeffry and Laurie F.

“Working with Mary and Heather was truly amazing. They are absolute professionals who made the entire selling process a breeze!

“Had an amazing experience, Heather was the absolute best to work with and extremely helpful in all aspects. We couldn’t thank her enough for the time and effort she put into helping me find the perfect condo!”

Rick and Ady W.

“We cannot imagine working with a better team than Mary Stewart and Heather Kaznoski.
They know the town of Marblehead, the pros, and cons of every area in town, the other realtors, and all of the town's real estate service providers like they have lived here for over 40 years, which they have! We were most impressed with the care and time they took to find out exactly what we wanted in a house, our budget, and what area of town suited us the best. They then made sure to show us properties that met our criteria, as well as a few that fell a bit short, so as to solidify our choices. They did all of this in a very difficult "sellers' market" with great professionalism, timeliness, and patience. When they located our dream home, they were excellent advocates, steering us through the competitive bidding process with timely advice and skill that most assuredly helped us win our home. We would most wholeheartedly recommend this "Dream Team" to anyone!”

“Mary and Heather were phenomenal! I never imagined our house would sell for as much as it did. They worked so hard and were incredibly organized. They made what can be a challenging time as easy as possible. Highly professional and will continue to recommend.”

I have bought and sold property in four countries. The care and professionalism from this team has been without parallel. Owing to Covid the negotiations were conducted over 12,000 miles apart. Cannot fault this service.
