Chapter President's Message

Dear Chapter Members,

As your chapter president, I am delighted to welcome you all to our chapter events throughout the year and to invite you to become active on the board and committees. We are fortunate to have an amazing group of chapter volunteers who have joined us to advance Upsilon Lambda’s initiatives.

Our chapter is also working to develop our chapter communications including a vibrant website, linkages to STTI headquarters through the Circle (STTI’s communication site), and dialogue about future directions.  Please add your thoughts to our discussion page!

Our chapter leaders look forward to welcoming you to chapter events and leadership opportunities with Upsilon Lambda!
