CCK Strategies, PLLC joins IR as the exclusive Accounting Services Member in US-Oklahoma. IR Global, the world’s largest exclusive network of advisory firms is delighted to introduce Eric Kunkel of CCK Strategies, PLLC. Eric has joined IR as our exclusive Accounting Services member in US-Texas. CCK was founded in 1997 by three young partners motivated to build a new type of CPA firm. John Curzon, Terry Cumbey, and Eric Kunkel took a big risk, leaving successful existing positions to form a new firm – one founded on the principle of “service.” The three established CCK, and in 2002, became members of the nationally recognized McGladrey Alliance of exceptional accountancy practices.
