About Me

Tammy Gwinn, a highly recognized Real Estate advisor, boasts seven years of successful experience in Mercer Island, the Eastside, Seattle, and neighboring communities.
With a solid foundation from a 25+ year career in the Puget Sound business community, she transitioned seamlessly into real estate after managing the PNW team for a Fortune 250 company.
Tammy's expertise in business development, long-term relationships, and negotiation skills define her client-centric approach.
Her majority referral-based business, coupled with a Broker's license and SRES certification, attests to her trustworthiness.
Beyond real estate, Tammy actively supports educational organizations, aging adults, adult support resources, and animal welfare, especially canine emotional support efforts.
As a 32+ year Mercer Island resident, Tammy remains an active community member with diverse interests in social activities, sports, yoga, golf, hiking, and travel, often seen with her 80-pound English black lab, Batman.
