Chase Counsel is not a high-volume tax-resolution practice. Attorney Chase Sizemore personally evaluates and leads each matter.

He also received trial-advocacy training through the National Institute for Trial Advocacy (NITA).

His experience extends well beyond a conventional tax practice, including nearly two decades working in South Korea and China on international legal and business matters and founding Teach Them To Fish Foundation, an international nonprofit working in Cambodia and Uganda.
