Allison did a great job not only helping to find the property before it was even listed, but also walk me through from the very first meeting to the closing. She is a true professional and a quality agent.

Awesome Again!!

From start to finish, my experience with Allison Grosse was extremely seamless. Her hands-on approach to the real estate business made my entire process simple, convenient, easy and rewarding. Allison is a natural fit for the complex real estate business. I'm so glad I had the opportunity to work with Howard Hanna Realtors. Great job!

Allison is very easy to work with. She was very friendly and attentive and wrote down all of our wishes and concerns. She was always available for questions as they arose, and was very helpful and comforting when it came time to pack and close. I would recommend Coach Realtors to my family and friends, in particular, Team Grosse.

Allison went above and beyond to help us with our sale and purchase. She took care of us like we were her children. We appreciated everything she did.

Wendy L. | Home Seller

It was a pleasure working with Allison because she has extensive experience and was always available to answer questions promptly. She politely calmed any anxiety in the selling process. She also recommended a contact in NC who helped us purchase our new home.

Ken S. | Home Seller

Allison was great with the sale of our house! She knows the market and it's movement and was instrumental in lowering our price at the exact right time to attract more buyers as the market started to turn from COVID! She was very knowledgeable, professional and down-to-earth!

Nick DeFeo | Home Buyer

I have had the pleasure of dealing with Allison several times and she has never let me down.She listens when you explain to her exactly what you're looking for and doesn't waste your time.Her experience and up to date knowledge of the market on the South Shore is the best! If you are looking for an agent who is straight forward ,works hard for you and gets the job done then Allison is the one!!

Allison was extremely helpful in every way. She was knowledgeable of the entire area as well. She was not pushy towards me at all and really was looking for a good fit for me. I'd recommend anyone to work with Allison to find their home and if I ever need an agent in the future I will be calling her.

When I was tasked with cleaning out and selling my parents' home, Allison could not have been more helpful. She knew the market and knew exactly what I needed to do and how I should price. She had quick and affordable sources for repairs, and handled everything. The whole process was as easy as possible, and the outcome was just what I wanted. I highly recommend Allison to anyone looking to sell a home.

Allison was a pleasure to work with. We were first time homebuyers and she guided us through every step of the process. She was attentive to our questions and quick to respond to any calls or texts. We must have looked at over 30 homes and Allison was always patient and ready to show us what we wanted. She made a stressful process go smoothly by being supportive, highly knowledgable and on top of everything. I highly recommend Allison to anyone looking to buy or sell a home.

We drove Allison Grosse crazy for a year & she put up with us & was more than gracious every step of the way! We couldn't have found the house of our dreams if it weren't for her patience & kindness.

Larry & Nicole Northorn | Home Buyer

We were so pleased, that I told Allison "8/17/17 is going to be "St Allison Day" Thank you!

James Phelan | Home Seller

Both my brother and myself live out of state. No one was at the house at the time of the listing. Allison always kept an eye on the house, especially during winter. She checked furnace, made sure we had no frozen pipes. We were very happy with her service. She was professional and courteous and would refer Allison to family and friends

Valeria Grogan | Home Seller

Working with Allison was a great experience. She was very attentive throughout the process and very helpful with recommendations on how to sell my home. She handles everything very professionally and extremely trustworthy. I would recommend her to anyone.

User8213903 | Home Seller

Allison is a true professional! We could not have asked for a better agent ! Because of her dedication and efforts our home was sold within three months. Allison was responsive to all our needs and was helpful throughout the entire sales process.

kas1999 | Home Seller

My experience working with Allison was great! Working with her felt like being with family. She handled both the sale of our Townhouse and assisted with the purchase of a new home. The sale of our home was frustrating at times (caused by the buyer). Allison was always there with a kind (and professional) ear. She understood my need to vent at times and always offered a calming word. Despite the difficult buyer, Allison keep us on track, making the process a bit less bumpy :-). Her knowledge of Real Estate trends and the current market was impressive. Her honest advice and coaching along the way proved to be successful. Allison discussed market appropriate pricing of our townhouse, which resulted in a quick sale. It was because of that quick sale, that my husband and I were able to put in a offer on our new home. We were one of four offers on our new house, with Allison's guidance, we were able to get the house. We couldn't be happier. I HIGHLY recommend Allison Grosse to assist you with the sale of your current home or purchase of your next home.
