TMS 2018 Walk-a-Thon

Each year, thousands of people participate in our annual walk-a-thon to raise money and awareness for Mast Cell Disorders. This year we invite you to create your own “Fundraiser Page” and share it with friends and family who will contribute to your effort of raising money for TMS.  You can select a distance of your choosing and walk anytime during the year. Using the campaign page allows you to raise money for a great cause wherever you are and whenever you are ready.
