About Mark Tennison

Originally from Texas, I’ve lived in New York City, Palo Alto, and Charleston, and have proudly called Denver home for the past eleven years. Before transitioning into real estate, I spent over 25 years as an award-winning entrepreneur and CEO in the healthcare staffing industry, where I specialized in high-level contract negotiations and building lasting professional relationships.

Today, I’m a nationally recognized real estate agent with West + Main Homes, serving buyers, sellers, and investors throughout the Denver metro area. In 2023, I was honored to be featured on America's Best list for exemplary sales production in 2022, ranking #467 in Colorado with over $19 million in residential sales volume.

I bring a strategic, relationship-driven approach to every transaction, grounded in integrity, experience, and a strong commitment to client success.

When I’m not working with clients, you’ll find me enjoying Colorado’s great outdoors—hiking local trails, cycling through scenic routes, or unwinding with a good book.
