We’ve helped raise more than $126 million for our clients. How can we help you?

For decades, state testing has shown young children from rural western Sussex County as being the least prepared for school in Delaware.

Six years ago, Longwood Foundation asked Horizon to assist Montessori Works with creating a new charter school to address this problem. The result, today, is Sussex Montessori, a high-quality, free charter Montessori school for 465 children in grades K-6.

The reason?
Horizon’s experienced team of associates

For more than 23 years, we have served clients across the Mid-Atlantic region, helping them solve and address a myriad of operational challenges including capital campaigns, marketing communications, fund development, facility renovation, construction, and raising more than $122 million for charitable causes in the process.
