About MMSI

MMSI launched in Severna Park, Maryland, in 1985 and has been firmly committed to the real estate industry for over 30 years. We built Membership Director on an accounting platform, guaranteeing standard accounting practices and full audit trails. Its platform was created to allow Membership Director to easily adapt and evolve as our customers' requirements do. This unique approach has allowed our customers to grow and incorporate new technologies as they became available without having to start over from scratch. Our personal service and dedication to our clients is unmatched in our industry and is one of the reasons that our average customer has been with us for over 18 years.
