The Grattafiori Group

A home is not a home because of its room dimensions or the color of its walls – It is about how you feel when you walk through the front door. It’s about the way you can instantly envision your life unfolding there. This is about more than real estate. It is about your life and your dreams.

In today’s complex real estate market, buyers and sellers need experienced REALTORS® who will prioritize their interests and needs. John and Karen, of The Grattafiori Group, understand that selling or buying a home is more than just a transaction, it’s a life changing milestone. They appreciate the opportunity to earn your business and your trust for life.

What They’re Saying

We loved working with the Grattafiori Group for the purchase of our home. They were there for us through the whole process. Would highly recommend their expertise and commitment.

Suzanne Goostree

We were searching the Acworth area for a new home. I arranged for personal interviews with key area agents. Before the meeting the Grattafioris began sending me potential homes based on our phone conversation. This couple is extremely well informed on the region, personable, funny and pay attention to the client’s preferences. They took pictures and measurements whenever I requested to save me a long trip, conducted a video conference walk through on the home we chose 20 minutes after it came on market to insure, we made an informed offer. I highly recommend them to anyone who doesn’t want to waste time and desires targeted selections. We had to deal with a rookie seller agent and difficult seller, but they made the situation easy. We have become friends over the last 9 months and that’s important to us. If I could give 10 stars…..

If only I could give them 10 stars! John and Karen were outstanding and always went above and beyond. My husband and I had to sell a family member’s home after a medical tragedy. We live out of state and Karen and John guided us through the necessary renovations and to a very successful sale of the property. They answered every question, always had a reliable recommendation and were efficient but compassionate. These are the people you want on your side if you are selling or buying a home!

Patty G.

Working with Karen and John was not only easy but they made the process of selling as stress free for me as possible. They are terrific to work with and extremely knowledgeable of the market and current real estate practices. I highly recommend them.

Renee Given

Wonderful people! We highly recommend John & Karen. Our home was sold in less than 24 hours. The Grattafiori’s were always pleasant and responsive throughout the entire process.

A. Nolan


It was pleasure to work with Karen and John Grattafiori. They listed and sold our Acworth GA home for top dollar.  We found the process smooth and hassle free, thanks to the efficient detail work they execute behind the scenes.  We would highly recommend them for your real estate needs.

Attention family and friends in NW Ga! If you are looking for a house, please see my friends Karen Heitz Grattafiori, John Grattafiori and Jennifer Clancy! They will work Super hard for you to get you what you want! We are blessed to have had them on our side. Great people!

Jamie M.

Karen and John are incredible! I literally have only great things to say. They got us the exact price we wanted for our home and not a penny less. They were pleasant, informative, and very personable. They answered all our questions (and my husband had a LOT, because he’s extra inquisitive), and  they did so in a very helpful manner. Even after the sale was done, they still keep in touch with us because they genuinely care. They are not only experts at what they do, but they are also authentically nice people. 5 stars all the way 🙂

Renee S.

The Grattafiori Team is the best in the business! Professional, honest, personable, reliable, knowledgeable and dedicated to making sure their clients have the best experience! I’ve used other agents in the past, and I will always go back to John and Karen.

David P.

John and Karen are a great team!! Selling a home then purchasing one is stressful, but having John and Karen assisting made both processes seamless. From their initial home visit I was impressed because they asked me what I was looking for in an agent/realtor. It felt great to have someone that you know you can trust. I highly recommend them if you are looking for a fantastic home selling/purchasing experience.

Melanie J.

Easy to work with! Always available! Works hard to meet your schedule. Willing to help research homes in the areas of interest and eager to send a list in order to set up viewings for the following days. Knowledgeable when questions arose, and able to direct me to other team members  that could help answer questions that they were not aware of.

Linda C.

John and Karen were wonderful to work with. They were knowledgeable, personable and caring. They made the whole process painless. I will definitely use them again. I highly recommend them!

Cathy T.

We have used Karen and John twice over the past several years. The first time was selling our home, and the more recent time was purchasing our new home. Both times they went out of their way to make sure everything was taken care of efficiently and swiftly. They were always quick to communicate  every step of the process with us and we’re very easy to work with.

Jayna N.

John and Karen were the first realtors I contacted (and only) about selling my home. Talk about good luck. Their familiarity with my neighborhood and their insight developing a marketing strategy was invaluable. 10 days on the market and very attentive to my needs, as I traveled extensively for  work. Not only are they great realtors, but a couple I now consider friends!

Thanks John and Karen!

Michael McCann

Great people to work with. Genuinely care about your experience and your needs. Some of the nicest people I’ve ever met. I would highly recommend them to anyone shopping for a house.

Bobby & Rosalind Siska

We not only used Karen & John for buying our home but they worked with us and sold our home as well. It was a great experience and they were very knowledgeable and considerate of our needs and wants. I will definitely use them again and recommend The Grattafiori Group to all my friends and family.

Brian McGregor

We sold and purchased with them. We had 3 full price offers in 3 days when we sold. We had our new home built and they guided us through the whole process including calling the builder for us. Always had good communication with us, John even answered my call while he was at his child’s ballgame.

Joe McNair

Karen and John were fantastic. I don’t usually like people in Real Estate. (I’ve been burned before.) Karen and John however, took away my anxiety. With the very first meeting, I knew we were in good hands. They were very upbeat and knowledgeable, and asked questions we didn’t think of, or were too afraid to ask. I would definitely recommend Karen and John to anyone trying to buy or sell a home. As a matter of fact, I have!

Rebekah McNair

John was so patient is showing us Countless houses until we found the perfect one! Karen made paperwork so easy and the closing process was very smooth because of her! They make a really great team and I’m so glad we used them!

Scott & Stephanie Martin

Great home buying experience with John and Karen. Very knowledgeable, very caring, and just overall great people. I would definitely seek them out for our next home purchase!

Michael Acree

We used the Grattafiori Group for both our buy and sell experience and it was amazing. We had a very specific ask…we wanted a property on a certain section of Lake Allatoona and were determined to get top dollar for our existing home. Karen and John not only found our dream home but helped us navigate the vagaries of buying lake property that abuts Army Corp land.

They then advised us of what the market was looking for in our very competitive neighborhood market. We took the advice and had multiple qualified offers within two weeks.

I can’t say enough about the support we received. I don’t plan to ever move again but if we did, there is no one else we would even consider using.

Curt & Jeanine Allen

God is so good! We are blessed to start off the new year in our new home!  I cannot wait to move in!  Huge thank you to Karen and John Grattafiori for the help in making it happen – best realtors ever!

Jenna & Noah Lucas

We are so excited about our new house!! Thanks to John Grattafiori and Karen Heitz Grattafiori at Keller Williams who helped us so much through the buying/selling process. They were so patient with us and were available every step of the way!! This is the beginning of many exciting changes for our family. Looking back, I was so impatient and wanted everything to happen on my time. God’s timing is perfect!!!!

Jodie Price

John & Karen were great in every asspect of my home selling. I needed to sell quick and they made it happen. They even helped me with a contact at my destination with finding a rental home untill I find a place to buy. Karen, John and KW are #1 in my book

Jay Bergalowski

John & Karen were always a pleasure to work with in selling our home. They really made it easy for us by always being there to answer our questions or address any concerns. John & Karen walked us through every step of the process from start to closing. They have a wonderful work ethic and are very knowledgeable. I  would highly recommend them to anyone.

Byron Whetstone

The Grattafiori Group was extremely helpful and knowledgeable. I would highly recommend them as Realtors. They are professional and always willing to go the extra mile.

Tammi Curti

Our experience working with Karen & John was excellent and we would recommend them to anyone who wants to purchase or sale a home. We appreciated their honesty, and working relationship.
