Testimonials

Dennis was wonderful to work with selling a home in Milford that I had inherited. He was thoughtful and did a great job explaining options and assisted me with making decisions about the property. He was professional and I felt he sincerely wished to assist me in the process which made it less stressful for me. I appreciated his work and dedication. Would recommend him highly.

Rick C.

Dennis Beirne was a pleasure to work with on my recent home sale. His knowledge of the market, leveraging of resources, and attention to detail were spot-on. So many decisions are involved in a home sale, and Dennis was a considerate communicator and intelligent advisor, throughout. I was thrilled that, with his efforts, we closed for more than my asking price. Simply put, Dennis is an excellent and thoughtful realtor.

Patricia Pino

Very helpful and made everything very simple for me. Extremely knowledgeable and patient in explaining the process to me.

Jennifer Gilbert

I have had the pleasure of working for Dennis as my manager and then later as a peer. Dennis is hard-working, honest, and generous with his time. He is highly intelligent, a quick study, and able to simplify, (without oversimplifying) complex subject matters. He is highly efficient with outstanding organizational and project management skills. He is likable, easy to work with, and someone who is readily and deservedly respected and trusted.

Brian

Having worked for Dennis for over a decade, it is not surprising that he has transitioned to the real estate industry. He has always demonstrated a strong work ethic, integrity and genuine concern for his employees and colleagues' personal and professional success. As a real estate agent, I know that he will bring that same level of passion and dedication to helping his clients navigate the complexities of the real estate market - and at the same time make the experience enjoyable and fun!

Jessica Murray

I had the great opportunity to have worked with Dennis for over 25 years. During that time, I have grown to respect Dennis as a highly competent and dedicated co-worker, exceptional problem solver and team champion, and most importantly, a valued friend. I have worked with Dennis on everything from small work efforts to multi-year, highly complex, and cross-divisional projects; for each, Dennis puts the same passion, attention to detail and willingness to go beyond expectations to get the job done and done well. Working with Dennis is always a pleasure not only for his work ethic but his ability to bring fun to the process. I highly recommend Dennis!!
