About Mary McTiernan

Originally licensed in 1989, I joined RE/MAX in 1991. I received the RE/MAX Hall of Fame award in 2003 and the RE/MAX 100% Club Award. In 1987, I earned a BA in Psychology from Carlow College. I am an Accredited Buyer's Agent, a FIVE STAR Real Estate Agent™ for customer service since 2010 and a consistent Multi Million Dollar Producer. As a long time resident of the North Huntingdon area; I enjoy helping buyers and sellers through the real estate process. I am married with 2 children and 5 grandchildren.

There are many qualities and skills that go into being an excellent real estate professional - integrity, in-depth community and market knowledge, marketing savvy, effective negotiation skills and a high-quality professional network, all of which are hallmarks of how I work.

That said, in my experience as a real estate professional, I've also found that providing the very best service is essentially about putting my clients first. This means keeping myself accessible, being a good listener as well as a good communicator, and responding quickly to your needs.

This "client first" philosophy has always been my approach and it requires me to continually improve my skills and ways of doing business. In addition, I've found that the latest technologies are enabling me to do everything I've always done, only much more quickly and efficiently. They've also helped me to extend the range of services I provide to my clients.

I have the education and experience so when you decide that you would like to buy or sell a home in the please give me a call at 724-244-4287 or email me at marymctiernan@comcast.net

“Every part of this transaction was done on time and as promised. You both were very professional and great to work with. We are very pleased, and of course, would hire you again.”

Sam & Marie H.

“Mary was a great asset to the selling of my dad’s home. She was always very responsive to questions and concerns that we had. Also, always very well prepared all through the process. She also was great when we had to have some work done following the home inspection. Everything you did was much appreciated by me, Dad, and our family. Thanks again.”

Ed F.

“Mary was very professional. It had been almost 40 years since we bought a home. Mary was able to explain all the changes etc. when buying a home. We are very pleased with the whole process of selling our home with Mary. Debra took wonderful pictures of the house calling attention to unique qualities of our house. Mary was very consciences of the paperwork – signatures and initials for any changes made during the process. We will surely recommend Mary to anyone seeking to buy or sell.”

Roberta & Bill P.


“The services that Mary and Deb provided for the sale of our home were very good. From the very beginning of the process to the very end we were kept abreast of everything that was happening. Mary kept us up to date of all of the showings and the results of each. We totally enjoyed working with both of them. P.S. Debra’s photos of the house were outstanding!”

Marcy & Chuck M.


“I felt Mary McTiernan went above and beyond my expectations. There were times I thought I would fall apart if it wasn’t for her patience guiding me through this process. She is an outstanding agent! This isn’t the first time I have bought and sold my home. Mary is the best. It was a pleasure working with her.”

Susan B.


“Exceptional Experience!! We remembered Mary for her pleasant personality from 5 years ago. So pleased we went with her to sell our home. The pictures were fantastic and feel they had a big part of selling our house so quickly. We would recommend Mary & Debra to anyone looking to buy or sell. Thank you so much for a positive experience.”

Dave & Pat K.


“Mary and Debra worked very well as a team. Mary was very patient as we first tried to “sell by owner”. We appreciated that very much in addition to the quick sale.”
