Buyer of 1507/1350 Main Street, Sarasota
My Wife and I were buying a home without an agent, and Ms. Mock was the seller's agent. She worked with us professionally, ensuring that everyone was well aware of the boundaries of representation, but still seeking solutions when problems arose. Very professional, and her network of local people is very helpful. I would recommend her to others, and would use her as a seller's agent in the future.

Buyer of 501/707 South Gulfstream Avenue, Sarasota
I had the most wonderful experience working with Roberta and her incredible team (Jessica) . My daughter, who works for a Sotheby’s affiliate (Daniel Gale) in New York, connected me with Roberta & Jessica, and from the very first meeting I knew I was in the best hands. They instantly made me feel comfortable, listened carefully to what I was looking for, and provided thoughtful guidance every step of the way. I had my heart set on staying in the building where I was currently renting, even though there wasn’t much inventory available. Roberta & her team kept a close eye on the market, and when the perfect unit finally came on, she moved quickly and skillfully to help me secure it. Thanks to her expertise, we successfully negotiated the deal, and the entire process was seamless, smooth, and handled with the highest level of professionalism. Roberta is truly exceptional at what she does—knowledgeable, supportive, and dedicated—and she made what could have been a stressful experience feel easy and enjoyable. I would highly recommend her, along with the Sotheby’s brand, to anyone looking to buy or sell.
Buyer of 501/707 South Gulfstream Avenue, Sarasota
My daughter in New York works for a Sotheby’s affiliate and introduced me to Roberta. From our very first meeting, we had an instant connection, and she—along with her wonderful assistant Jessica—took exceptional care of me throughout the entire process. Since I was only interested in purchasing a condo within the Essex House, my options were limited. When two units became available, Roberta and Jessica guided me through the negotiations and helped secure the perfect fit for my needs. I would highly recommend them to anyone—they will truly take great care of you
