Lisa G.

Executive Director

Our organization has worked with Muster since its startup and they continue to adapt to customer needs. I have worked with other e-advocacy firms and nobody compares to Muster's attentive customer service! They would probably answer my call for help at 2 a.m.! They are reasonably priced and easy to use. I like that they provide for contact with local elected officials as well as federal and state because they are so grassroots oriented.
