Bio

I have been in Real Estate for over a decade. Not only am I consistently at the top of my brokerage and Maryland’s list of agents, I have also purchased, renovated, rented and sold my own properties throughout the state. This personal experience along with my background in IT and customer service helps to ensure success for you as a homebuyer, seller, renter or investor.

As the team leader for Diamond Home Group of Cummings & Co Realtors, I have led our team to close $50m+ in sales over the last 3 years as we continue to grow and add services to our portfolio to differentiate ourselves from local competition. We have been recognized as Staging Experts, Seller Specialists, Accredited Buyer Representatives, marketing professionals and are members of the Million Dollar Real Estate Association of Harford County and Baltimore Real Producers (the top 4% of Realtors out of the 12,000+ in the Central Maryland area!)

Prior to Real Estate, I spent many years in the technology and hospitality industries – honing skills that serve me today such as marketing, negotiation, communication and superior attention to detail. Skills that ensure success for our clients time and time again.

Our Team:
When selecting a diamond, you should look for the 4 C’s (Clarity, Cut, Color and Carat Weight.) At the Diamond Home Group, clients who select us enjoy the following qualities from our agents:

* CLARITY – Like a diamond, we want the process to be crystal clear. We are with you every step of the way from start to settlement.
* COMMUNICATION – Call, text or email us at any time. Proactive communication from us to you is key.

“Looking for a Realtor, 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.

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.

"Just purchased a home with Steve Williams, who was an exceptional agent from start to finish. Everything he brought to the table empowered us as buyers: his general knowledge of the industry, specific knowledge of the area in which we were looking, and help navigating a particularly tricky situation that unexpectedly arose with little time to sort things out. Cannot recommend Steve enough."

"I have sold several homes over the years and no sale went as smoothly as the one with Steve Williams as my agent. Besides getting a buyer for my home within two weeks of going to market and with a price over asking , everyone involved executed an impressive selling process from start to finish. Their communication was outstanding, especially the "what to expect" emails. I was well informed of what… Read MoreRead Less

When I wanted to grow my space, she helped me sell my condo and helped me look for my second home. She was so patient with me; we spent months looking for both houses. When I t… Read MoreRead Less

"When I was looking to buy my first home, Laura was recommended to me by several coworkers. She took the time to listen to what I was interested in, find me homes within my budget, and help me with the entire buying process. I didn’t feel like a number or a sale - she truly cares. I 10000000% recommend her, and if I ever plan to move, she is my first choice."

"Laura provided exceptional services, going above and beyond. She was amazing through the whole process - we received an offer and signed at asking price. She is very knowledgeable of the greater Baltimore area. I would recommend without hesitation."

From that moment on, we knew we had found not only an incredible realtor but a lifelong friend. When we outgrew our first… Read MoreRead Less

"One of the best decisions I've made recently was to work with Jess on my recent home purchase. It can be tempting to purchase a home without a realtor, but simply put - I would not have finished this process without Jess. I wish I could say it was a seamless experience, but there were substantial hurdles along the way and Jess managed all of them effortlessly. In some cases, people can sometimes w… Read MoreRead Less

"What is there to say about Jess? There wasn’t a minute of the day that we didn’t run to her with all of our stress, worries and what-ifs where she didn’t put us back at ease in a moment. She’s responsive, kind, interested, and she genuinely cares about her client’s future. She worked hard to make it happen. We went through a roller coaster together in this unpredictable market.
