About Margaret O'Sullivan

I became a REALTOR® in 2012 and knew instantly helping others achieve their dreams was my passion and what I was meant to do.   

My business philosophy is simple, 

"Work Hard and Do the Right Thing"   

This philosophy has proven to be effective as I continue to be a multi-million dollar sales agent, year after year. 

I utilize cutting edge technology and never-ending dedication to providing the highest level of customer satisfaction to help you through one of your most significant and intimate financial decisions.

What Clients Are Saying

Margaret is simply amazing! She takes “white glove service” to the next level. She truly went above and beyond, time and again. We would highly recommend Margaret to partner with when buying or selling a home. She is honest, knowledgeable, professional and especially “tuned in to the market”! You will be happy you selected Margaret O’Sullivan to represent you and your interests with such an important, life impacting transaction…….although she treats it much more than just a transaction!

Pam and Tom Reading Seller

"I just bought my very first home, and I am so glad that I found Margaret as my agent. Margaret’s philosophy is that the most important thing is that her client is happy. As a first time home buyer, she explained every single detail to me, made sure we stayed on track, fought for me every step of the way, and encouraged me when the process felt overwhelming. I was 100% confident that Margaret was in my corner every step of the way. She is the best agent I’ve ever worked with during my very long search for a first home. I would hire her again in a heartbeat, and you should too!"
