Our History

McGuire Sponsel was established to be a true value-add to firms. What started as a discussion around a kitchen table developed into what is now a trusted resource to hundreds of firms nationwide. Our team partners with firms of all size and specialties by acting as an extension of the respective firm.

Our team serves as a complement to the exceptional service and value that a respective firm’s clients have grown accustomed to. We treat each client as if they are our only client. While other firms may offer one of our service lines, no one in the industry serves clients as well as McGuire Sponsel.
