5 /5 Cheryl Clarke: Efficient and caring tax professional. Stays current with tax code. I’ve had Mr Duff as my tax professional for so many years I’ve lost count. I know it’s been more than 10 years. If you din’t know more than what I know about your business or your attitude is off base, I don’t stay. I’ve been very pleased with his advice, friendly intellectual conversation , professional knowledge about the tax laws and promptness.
