About Sebastian

After studying neuroscience at the University of Michigan, I began my career in sales before discovering my true passion: helping people navigate the complex world of real estate. Today, as the Broker of Coldstone Group, and with active licenses in the mortgage and title industries, I bring a uniquely comprehensive perspective to every transaction.

Leading a small but high-performing team of agents, I’ve personally guided clients through hundreds of successful transactions. From first-time buyers and seasoned investors, to sellers looking to maximize their returns. My background in both analytics and psychology gives me the tools to negotiate strategically, communicate clearly, and deliver an experience that feels seamless from start to finish.

As a full-service advisor, I’m proud to offer a true white-glove experience, handling every detail across the real estate, lending, and title process so my clients can focus on what matters most: their next move.
