About Tyler

Being a real estate broker was a natural move for Tyler’s career. With his expansive background in the industry and his compassionate, genuine personality, Tyler brings a different experience for his clients when buying or selling a home.

Throughout his life, Tyler has always valued genuine and authentic connections with the people he meets and believes that, in addition to his passion for real estate and the community, this is what stands out to the clients he represents.

Tyler is a native of the Portland area, though he is licensed in Oregon and Washington. He grew up in Southeast Portland and graduated from Cleveland High School and later attended the University of Oregon where he received his B.A. in Philosophy.

In 2013, Tyler joined Proud Ground, the largest Community Land Trust in the Pacific Northwest. While there, he worked as a Project Manager for home repair & rehabilitation, in addition to serving as their Principal Broker in Oregon and Managing Broker in Washington.

Tyler has extensive experience in buying and selling homes including short sales, foreclosures, and investment properties in Multnomah County, Washington County, Lincoln County, and Clark County. Tyler knows it’s important to give back to the community. Prior to his time at Proud Ground, Tyler worked as the Club Director for the Boys & Girls Club before going on to work as the Site Supervisor for Multnomah Education Service District’s Outdoor School.
