Raised in Livingston County, Sebastian Cowgill attended Hartland Schools before continuing his studies at the University of Michigan, where he focused on neuroscience. That background, centered on human behavior, decision-making, and pattern recognition, now informs his approach to sales, negotiation, and market strategy.

What began as a college interest in real estate quickly evolved into a full-time pursuit. Sebastian was drawn not simply to transactions, but to the complexity behind them: the psychology of negotiation, the effects of marketing, and the responsibility of guiding clients through high-stakes decisions.

As the oldest of four siblings, competition and accountability were early constants. Years of organized athletics and academic forums sharpened that edge, reinforcing a mindset built around preparation, performance, and measurable outcomes.

After establishing himself as an agent and later as an associate broker, Sebastian recognized an opportunity to build something different. He envisioned a brokerage rooted in strategy, where clients could consistently expect informed guidance, structured planning, and disciplined execution.

With additional experience in mortgage and title operations, he developed a comprehensive understanding of the full transaction lifecycle. That perspective became foundational in redefining the client experience and ultimately led to the creation of Coldstone Group.
