About Us

CELCO was established by one of our industry’s first leaders, Carol Enters, who founded the company to handle list brokerage and list management services for the non-profit community which today still represents 100% of our business.

Barbara Sims purchased the company in 2001 and guided it until her retirement at the end of 2023, when it was purchased by Kelly Leech and Andrew Giffen.

CELCO has a diverse array of nonprofit partners, having established a reputation for delivering superior service based on deep fundraising expertise.

Our brokers and managers have vast experience, and our support staff has been trained to learn issues beyond the basics of lists.  We are not simply your list source, but are studied and proficient in:  marketing trends, fundraising strategy, file health analysis, budget development, modeling, merge purge, direct mail production, and privacy and other issues affecting all mailers.

We are dedicated to client and staff success.  We carefully monitor our staffing to ensure the right mix and talented people are in place to achieve the best possible workplace, service and products.
