Rotary is the world’s first and largest service organization whose members form a global network of business, professional, and community leaders volunteering their time and talents to serve their communities and the world. Rotary is not a business networking organization. Rotarians focus on 'Service above Self' as a commitment toward bettering the world around them. Strong fellowship among Rotarians and meaningful humanitarian service projects characterize Rotary worldwide. Rotary International is working to eradicate polio, end poverty, and promote world peace and cultural understanding.

Buffalo Grove Rotary supports many local charities and community initiatives including hunger relief, safety programs, Special Olympics, park improvements, school programs, and student exchanges. Beyond their local efforts, its members have travelled to global service projects that include providing fresh water in Africa, development projects for schools in the Guatemalan jungle, and immunization efforts to eradicate polio in India and Nigeria.
