The summer of 1998 was the last year the White Plains YMCA was able to operate the White Plains Summer Day Camp in Greenwich using a field on King St. The Brunswick School purchased the property and the YMCA camp was without a home. Seeking a new campsite, the YMCA of Central and Northern Westchester purchased an abandoned camp in Putnam Valley. Formerly known as Madison-Felicia, it was owned by the Hudson Guild. At Christmas 1999, Combe Inc. announced a gift of $300,000 to ensure the opening of the camp in the year 2000.

On October 9, 2000, the YMCA of the USA recognized the new Putnam Valley/Camp Combe Branch. Since then the camp has been allowed to grow and prosper. Combe Inc. continues to have an annual workday at the site as well as supporting capital improvements. Recently, Master Card, IBM, Pepsico, and other companies have assisted in the rapid development and expansion of the facilies at camp.

The camp now serves the needs of over 500 children a day for a 10-week period, resulting in over 4000 camper weeks of service on site.
