Diane has sold two houses for us now. Her knowledge, drive, enthusiasm, and professionalism make her a topnotch agent. She is also a pleasure to work with. I recommend her without hesitation, and if we have any future real estate transactions in Metro West, we will absolutely hire her again.

My family met Diane a few years back when we were looking for our first house and now we have bought three houses through her in the past two years. She understood our needs and wants and used her experience to help us find the best houses for us. Her enthusiasm, communication, and knowledge are top notch. She would take the time to explain everything in details, which we greatly appreciated. I would recommend Diane to anyone looking to buy or sell a house in the area. My whole family has been happy to have dealt with her and will continue to do so in the future!! 1002 Pleasant Street, Framingham- The Noor Family

Diane B. Sullivan is the best realtor I have ever worked with buying and/or selling homes in Richmond, Baltimore, upstate New York, or CT.

Her initial marketing presentation was so far superior to any other realtor who made their "pitch" it blew away "any" competition whose marketing plan I solicited.

They all come with their book (pages and pages of broad brush "sale comp's" supporting their recommendations for (1) realistic selling price, (2) open house schedules, etc., but when questioned, Diane put her finger on the exact house within 3 seconds while the others could not remember, could not find the page or house when asked specifics.

She knows the real estate market backwards and forwards in Framingham, and is on top of any/all changes THE DAY it happens.

She is "the best" when it comes to follow up, negotiating skills, and best part, she is honest about any question or tough decision you will encounter, as either buyer OR seller.

I cannot recommend Diane Sullivan highly enough.   

She is AAAA++++ # 1 in my book.   She is a "must" whether buying or selling in the Metro West area.   She is on top of all closing details, inspections, etc.  When the calls come out of the blue for people wanting a private showing, she turns no one down, makes no false assumptions, and is a great sales person when accentuating the unusual advantages that will affect maintaining the "asking price" for the seller.

The Pelham Queen- Diane B. Sullivan

I had just moved my mom out of her Pelham Cape that she had lived in for 65 years. I moved her to a facility which is very close to my home in Michigan. I live 750 miles away from Natick. I needed a competent real estate agent whom I could trust to make good decisions in the process of selling my  mom's house. I was aware of Diane Sullivan's reputation as the "queen" of Pelham when it came to selling my mom's house. She made simple and practical suggestions as to the best way to stage the house to make it look it's best. She even brought in a couple of her own pieces of furniture to help improve the look inside. All of these suggestions cost just a very minimal amount of money. Because of her suggestions I was able to sell the house for the asking price in just a couple of weeks! I was so happy! Diane is very easy to work with, and a real "go-getter"! This woman rocks! I would highly suggest that you contact her for your real estate needs!

It is our great good fortune to have found Diane Sullivan as we sell our house. My husband did a lot of research and was impressed by Dianes success. Nonetheless, we spoke with other Realtors in the area and knew immediately there was no contest.

There are a number of projects that need to be completed before getting on the market and we could not have a better partner. She has a clear sense of what SHOULD be done, what COULD be done and what is unnecessary. Once she helped us determine which projects we ought to undertake, she helped determine the order in which they should occur and had suggestions on who might help with them.

Along with what appears to be boundless energy, she possess that rare combination of laser focus and flexibility. She is responsive, diligent and accessible.

I was a realtor in Framingham and know what is necessary to get a house sold. It is an art as much as a science. Diane has mastery of both.

My husband and I could not recommend her more highly. Sincerely,

Valerie Coyle

Diane represented us on the sale of our home and purchase of a new home. We had known Diane personally for five years and knew that she was a caring and enthusiastic individual. When we approached her about selling our home and purchasing a new one, she had pragmatic, helpful advice, and a commanding knowledge of available inventory, the process, and priorities.


Diane helped us get our home ready for sale in a very short period. She had a stable of competent contacts for various tasks we needed accomplished, but never pressured us to use them. Having these folks available was extremely helpful. All of them conducted themselves with the same competency and dependability that we experienced with Diane.


When it came to setting a price on our home, Diane was near clairvoyant in predicting the appropriate starting price and how negotiations would go. As a result of her understanding of the market, inventory, and assessment of our home, we had multiple offers, and found very qualified buyers in an extremely short period of time.


Regarding the purchase of our new home, Diane was extremely responsive, and a great communicator. She helped us navigate the waters and made what could have been a very complicated and stressful situation much easier to handle.


We could not more highly recommend Diane. She is not only a competent, dedicated professional, but she is also a wonderful and caring person and a steadfast advocate for her clients.

Diane was tireless in helping my wife and I both sell our house and buy a new one. She did an excellent job of shepherding us through the difficult process of choosing between towns and neighborhoods, showing us what we asked for, then helping us understand what we could afford, while still meeting our specific needs in a short period of time. She is flexible, honest, and knowledgeable.

Diane has a great way guiding you to decision with evidence and experience while allowing you to make the final call. When she was away for a week during our search, she made sure we were taken care of by a capable colleague. Closing on a house is a stressful process but she kept us informed and at ease during the toughest times. She even paid off our last water bill! (we paid her back of course...). Customer service at its best.

I want to thank you so much for all the effort you put into selling our condo and finding the home of our dreams!  We have worked with realtors in the past and I can truly say you were by far the most professional, hardest working, friendly and available agent.  You put timeless effort into selling our condo and you were available on the drop of a hat when we were searching for our home.  I will never forget the numerous nights we were all up until midnight going back and forth on our offers!  You were so knowledgeable and you were always looking out for our best interest.  Having an 11 month old son, being pregnant, selling and buying a home all at once seems overwhelming...but somehow you made it all come together!  Now that we are settled, have the new baby and our gorgeous home...I want to sincerely thank you.  I have recommended friends to you and will continue to do so.  Thank you Diane!

Diane worked non-stop to find us our first home. Just when we were about to give up on our search, Diane called and said "I have the perfect house for you!". Sure enough, we made an offer in the kitchen of that house that very day. Diane works hard to know you and what you need and want in a house. Her efforts definitely worked for us...we have the perfect house for our family and couldn't be happier.

Diane Sullivan was my real estate broker for the sale of my house this past June (2011). I had contacted her a year earlier and asked her to give me advice on how to present my house in the best available light. Diane did a complimentary walk-thru and suggested several inexpensive improvements which proved to be "right on" when I put the house on the market one year later. Diane was proactive in scheduling open houses and marketing the property and as a result of Diane's efforts, my house sold in 2 1/2 weeks, an incredible feat in this tight housing market.  I was extremely impressed with Diane's professionalism, availability, and willingness to go "the extra mile" for her client, and I highly recommend Diane Sullivan as a real estate broker.
