About Us

Allyn & O’Donnell Real Estate Agency, Inc. has been a locally owned and operated full service real estate company since 1888.  

It was started as The Allyn Agency by Henry Allyn and his son George, with offices in the Marble Building on High Street in Holyoke.  In 1933 the name was changed to Allyn & O’Donnell when Edward O’Donnell joined the firm.  

In 1995 Walter Nalesnik became the owner and he continues to operate the company with the same principles and integrity that the firm was founded upon.

Our real estate agents have a wealth of experience and knowledge that they are eager to share with our customers. 

We offer residential sales, commercial sales, commercial leasing and residential appraisals.

"I just wanted to say thank you so much for all your help.  You really were a trooper in helping me find my new home.  We had to kiss a few frogs before we found my prince.  I really appreciate all of your time, hard work and effort."

"Just wanted to thank you again for all you did with the sale of our house.  Even though the buyer held things up a bit, it was pretty quick in all.  Thanks for everything. Best of luck on more successful sales!!"
