Brian Zack of Diamond Home Group of Garceau Realty

When searching for a realtor, we had a clear list of qualities we were looking for, and Brian checked every box—attention to detail, personable, communicative, and always focused on our best interests. Brian and his team guided us seamlessly through both the selling and buying process. Everything went flawlessly and exactly as planned. The Diamond experience was truly top-notch. If you’re looking for a team to help you navigate what can be an overwhelming process and make it feel effortless, look no further.

Looking for a relator, then Brian is the one for you!! He sold our house in 2020. When this move came along in 2026, he assisted us for over 18 months in finding the right house for us. He is professional, friendly, responsive, and always looking out for his client. He is extremely knowledgeable about the location we chose for our house. He goes the extra mile to ensure the client is happy with everything. He provided recommendations for contractors in the area, to help make our transition smooth. So happy we chose him. I highly recommend Brian Zach as a relator if you are looking to buy a house or sell your current house.

Brian recently helped us sell our home and did a fantastic job. From our first introduction to closing, Brian was professional, responsive and understanding. He is very knowledgeable about real estate laws, rules and practices -- and if he was unsure of a question or approach he would research the topic and provide an answer with supporting information. He and his team were helpful throughout the entire process. I definitely recommend Brian Zack!

Brian Zack and his team were recommended to us from previous clients. We were moving from Baltimore County to Harford County and didn’t know of any realtors in the area. From start to finish, Brian and his team were there for us every step of the way. Neither my wife nor I had bought a house in nearly 30 years. The process had changed a bit and was a little daunting for us. However, Brian made the transition much easier. He helped getting our house staged properly to be listed for sale. He did such a good job that our home was sold 2 days before it ever hit the open market and at $5000 over list!!! On the backend, the sale and moving process to our new home was seamless. If you require a Realtor that has your sale, moving, and buying needs completely covered, look no further than Br

Brian went above and beyond in the sale of our property. We were so impressed with his marketing expertise and collaborations with the videographer and photographer to showcase the uniqueness of our farm, which ultimately lead to multiple offers. His attention to detail and great communication really put us at ease throughout the process. Highly recommend!
