The West Michigan Agency Network (WMAN) was formed by Crosby and Henry, Inc. in 1998 as the local Master Agency of the Strategic Insurance Agency Alliance (SIAA). Crosby and Henry, a 150 year old, family owned insurance agency, uses its deep company relations and excellent industry reputation to help promote WMAN and its member agencies. Since 1998 WMAN has helped dozens of independent agencies reach their goals of profitable growth and success. Using the national resources of SIAA and our Strategic Partner Companies, combined with the reputation, experience, knowledge and relationships developed locally over decades, WMAN provides the path and tools needed by the independent agent to prosper.

SIAA is the nation’s largest alliance of independent insurance agencies, having signed over 5,300 Member Agencies in 48 states through 48 Master Agencies, producing $5,700,000,000 in premium. SIAA grew by $900,000,000 in 2014 despite a soft market.
On average, more than one insurance agency joins a Master Agency partnering with SIAA daily. 1.25 in 10 Independent Insurance Agencies are or have been SIAA Member Agencies.
