Etherio buys Stringfellow Management Group to expand association management reach

Etherio said Monday it acquired Stringfellow Management Group, adding more than 60 association management professionals and broadening its national AMC footprint. The deal lifts Etherio’s association management practice to more than 300 team members across 30 states and reinforces its client-specific operating model.

Why it matters: - The acquisition expands Etherio’s association management scale and adds depth for clients that need full-service support. - The combined practice now gives Etherio a larger national footprint, which can matter for associations seeking specialized staffing, technology and operational resources. - Etherio said the deal strengthens its client-designed approach, rather than pushing associations into a single operating model.

What happened: - Etherio announced Monday that it acquired Stringfellow Management Group, an AMC Institute accredited association management company based in Forest Hill, Maryland. - Stringfellow Management Group adds more than 60 association management professionals to Etherio. - SMG joins Etherio Association Management alongside Association Management Strategies, which Etherio acquired in 2025. - Etherio now says its association management businesses include more than 300 team members working across 30 states. - The company operates from offices in Atlanta, Boca Raton, Denver, Washington, DC, and Maryland.

The details: - Stringfellow Management Group was founded in 2012 by Fred Stringfellow, CAE. - SMG built its business around close client relationships and full-service association management across multiple industries and professions. - Etherio said the addition deepens its bench across its service offerings and increases its ability to meet the needs of different associations. - John Flatley will continue to lead the combined association management practice as Managing Director of Etherio Association Management. - Fred Stringfellow, CAE will join Etherio as Executive Vice President of Etherio Association Management. - Both SMG and Etherio Association Management are accredited by the AMC Institute, a distinction held by a small percentage of association management companies worldwide. - The two organizations will combine their accreditation under a single certification over the coming year. - Existing account leadership, client teams and day-to-day contacts will remain in place. - Integration of the two practices will proceed over the coming months.

Between the lines: - Etherio is signaling that scale is useful only if it supports client service, not as growth for its own sake. - The transaction also suggests Etherio is building a more consolidated AMC platform while trying to preserve local relationships and customized service. - The AMC Institute accreditation gives the combined business added credibility in a crowded industry where certification is relatively rare.

What's next: - Etherio and SMG will work to unify accreditation under one certification within the next year. - The two practices will continue integrating operations gradually over the coming months. - Clients should see continuity in leadership and service while Etherio absorbs SMG’s team and capabilities.

The bottom line: - Etherio is using acquisition to scale up association management without changing the client model it says differentiates the business. - More information
