Mark Diehl has been a fantastic accountant. Not only have I rarely ever been sent to his voice mail, as he answers which is incredible for immediate information, but he has saved me $$$ time and time again. Most recently, he asked me about a business transaction that I had NO idea existed. RECOMMEND him HIGHLY!!!
