The partners and staff of Weiler & Company volunteer and serve on many not-for-profit boards, and bring that experience to leverage our involvement as a firm in your not-for-profit.  If there's one thing we understand, it's that it can be very difficult to support and manage your not-for-profit and its board.

We have served for several years as the external advisors to many not-for-profits in South Western Ontario, including United Way of Guelph and Guelph Wellington Hospice.
