His background in real estate technology made it easy for me to communicate my ideas to him. I value his opinion and will lean on him in the future for other ventures."

Anthony Gaitan
Blockbasin CEO and Real Estate Client

"Sean and I worked together at Auction.com/Ten-X, his ability to quickly manage multiple priorities with different timelines made him a pleasure to work with. He impressed me with his real estate knowledge and reputation for getting great deals on Brickell Condos. Outside of Auction.com I hired Sean to help me find an apartment that I live in now with my wife. I'm grateful to have worked with Sean and hope to do so again!"

Jonathan Katz
Senior Director at Ten-X and Real Estate Client

"If you have a need to update your website or create a site, I highly recommend you start your search with a free consultation from website designer Sean McDonnell. I trust him with my projects and to be a guest speaker in front of my digital marketing students. Sean's work is of the highest quality and priced fair."

Maximiliano Ramirez
Professor of "Marketing in a Digital World" @ The IDEA Center of Miami Dade College

"In the 2 years I worked alongside Sean I witnessed first hand his ability to excel at not only the core elements of his job but also the tasks that well extended beyond the scope of his role. His willingness to learn and take on new responsibilities was contagious setting the tone for our office's work ethics."

Ruby Jasmin
Colleague at Ten-X and Real Estate Client, Solutions Architect at Dataremote

"Sean was instrumental in my most recent move. He exceeded my expectations in his knowledge of the market. Sean was patient in the selection process. He showed us many properties. Once we found the right fit he could have rushed the transaction.. but instead helped us negotiate resulting in an even better deal."

Matt Gordon

"This was a really fun experience. My friends and I had a great time learning how to surf. Unfortunately the wave gods were not on our side, but Sean made the best out of it. He was on time and very good at giving instructions. Super chill and flexible. I'm actually looking into taking more surf lessons now, it was just that cool."
