REALTOR, Associate Broker (18 years experience)

Buyer's agent
Listing agent

Real Success in Real Estate: Making real estate dreams a reality in the Seacoast of NH and beyond for over 18 years. Licensed in both NH & ME.

With over 18 years of experience in real estate in the greater Seacoast area of New Hampshire and Maine and a top producer for eight years running, my clients tell me that I am their most trusted advisor, and my negotiation skills are exceptional.

Buying or selling a home can be complicated. Leave the details to me.

As one of Berkshire Hathaway Home Services Verani top producers (top 1% of realtors on the Seacoast) I offer a wealth of knowledge to both buyers and sellers looking to work with an
experienced realtor.

I raised my own family here and have deep rooted ties in both New Hampshire and Maine. I can show you the ins and outs of each town, share my knowledge on area school districts and provide you with the latest local real estate market trends.

And, because of my longstanding, successful career in real estate I am able to provide a wealth of knowledge with respect to mortgages, insurance and inspectors.

Prior to becoming a realtor, I enjoyed a successful career in the medical sector including nursing, medical office management, pharmaceutical sales and medical research.

Buying or selling a home with me is much more than a transaction. It’s a relationship that I will maintain for years to come!

Experience is what sets me apart.

Real Success in Real Estate



Working with Mary was an absolute pleasure from start to finish! Her professionalism, expertise, and dedication to ensuring a smooth sale were evident throughout the entire process. From the moment I decided to list my condo that I've lived in for 27 years, Mary guided me with valuable insights and market knowledge, helping to set a competitive price that attracted several interested buyers. Throughout negotiations and closing, Mary was available to address any questions or concerns promptly, providing me with peace of mind during what can often be a stressful time. Her communication skills were commendable, keeping me informed throughout the process to ensure a seamless transaction. Thanks to Mary's expertise and guidance, my condo sold quickly and at a fair price. I couldn't be happier with the outcome and highly recommend Mary to anyone looking for a top-notch real estate agent. Five stars all around!

Mary did a great job. She understood what we wanted and did not want in a new home. We loved working with her and could not be happier in our new home.

- Gregory M

I found that Mary was very informative and professional. Also very patient with us. She understood what we were looking for in a home and helped us find it.

- Donna M

Mary Strathern was outstanding and very supportive throughout the entire process from evaluating the new house to closing with the lawyers, sellers, and mortgage company / loan officer. Would recommend Mary to anyone seeking a solid, committed, and exchanging professional that would be able to guide you through the tedious and stressful process to purchase a new home.

- Thomas M

Mary is amazing! She is aways able to provide the information and guidance that you need, and her ability to remain cool headed no matter what comes up provides so much reassurance and confidence. And the results she gets are phenomenal! We would never consider using another agent in the markets she serves!

Mary made a difficult process much easier to get through. She gave me great advice and guided me through out the entire process. She listened and truly understood what I needed in my next home purchase. She got my current home under contract in less than a week. She then at the same time directed me to my new home that she had already checked out (for me)! My new home meets so many of my family needs. It's in a perfect location and is move in ready. Closing on both houses on the same day, only a few weeks later, was stress free. Mary and her team were on top of everything! It took so much stress off my shoulders! Forever grateful for choosing Mary and I def recommend her for your home buying or selling needs!

Mary’s experience clearly shows through when it came to all aspects of the sale of our house. Selling a home can be stressful and she made it as easy a process as possible.

- Paula R

We can’t say enough good things about Mary. She was extremely helpful and professional during the entire process of selling our home. Mary’s knowledge of the real estate market on the NH seacoast was exactly what we were looking for in a realtor!

Prior to selecting Mary for my real estate agent, I researched real estate agents and home sales in my area. Mary stood out. Mary priced my home right from the start and provided me with options on how to best showcase my home. She returned every phone call and email immediately. She was always available to answer any of my questions. Mary kept me informed as to the progress of the sale and let me feel like I was a valuable part of the process. Selling and buying a home can be extremely stressful, but Mary using her expertise, calmness, and professionalism made it such an easy process for me. I can’t thank her enough.
