Camp Sunshine, a retreat in Casco for children with life-threatening illnesses and their families, received a $515,000 donation Monday from Tropical Smoothie Cafe? as proceeds from the national smoothie and sandwich chain’s National Flip Flop Day campaign.

Tropical Smoothie Cafe? has now raised and donated more than $2 million to Camp Sunshine through its Flip Flop Day fundraising.

On Monday, more than 250 family members, volunteers and staff looked on as Mike Rotondo, Tropical Smoothie Cafe?’s CEO and president, presented the $515,000 check to Camp Sunshine Co-Founder Anna Gould and Executive Director Matthew Hoidal.

Rotondo was joined by members of the franchise development and support team, along with several Tropical Smoothie Cafe? area developers, store owners and employees who are volunteering at Camp Sunshine this week as part of Tropical Smoothie Cafe? Week.

Tropical Smoothie Cafe? raised the funds during its seventh annual National Flip Flop Day, which took place in June at each of the more than 340 locations across the country. Stores gave away free smoothies to flip flop-wearing customers, who were also encouraged to make donations to Camp Sunshine.

In addition to the $2 million already raised, the chain last year also pledged to provide $1 million for Camp Sunshine’s endowment – the largest corporate gift of its kind toward sustaining the Camp Sunshine program in perpetuity.

Camp Sunshine is located on 23 acres of donated land adjacent to Point Sebago Resort on Sebago Lake. Since its inception in 1984, Camp Sunshine has provided a haven for more than 40,500 individuals from 48 states and 22 countries.
