For four decades, SD&A has raised funds, sold subscriptions, and grown membership for the organizations that shape our cultural life — one conversation at a time.
“SD&A has always been one of the lead telemarketing vendors when it comes to results, operations, and call quality. I've worked with their firm for almost two decades, and the consistency and retention of staff and high standards for quality service have held throughout that entire time. Whether you are looking for a vendor that can handle complex data, multiple types of calling, strong donor cultivation or all of the above, SD&A is always a great choice.”

“SD&A has been a trusted Mercy Corps partner for many years, supporting our annual giving, emergency response, and sustainer campaigns. We appreciate their hands-on approach and close collaboration with our team throughout the planning and execution of each campaign. We trust their experienced representatives to engage our donors with the empathy, respect, and professionalism that reflect the values of Prosper Global (Formerly Mercy Corps).”

“SD&A has been a true thought partner to the International Rescue Committee, helping us dramatically increase donor lifetime value and reach more donors at a time when that growth mattered most for our mission. Their team brings both strategic insight and genuine care to every TM campaign, and they've consistently found ways to deepen donor relationships while driving measurable results. I'd recommend SD&A to any nonprofit looking to expand its reach and grow long-term donor value; they're a partner you can trust to show up as an extension of your own team.”
