I have referred many clients to Bill Hartsock over the past 6-7 years for matters requiring the expertise of a tax attorney. Some had complex tax issues...others less complex. In every single case, the client would get back to me after meeting with Bill to thank me for the referral. They compliment him on his knowledge, his ingenuity in resolving issues, his friendly manner and his reasonable fees. I have never had anyone report anything other than an excellent experience. I will continue to refer clients to him...and to no one else. One could not have a better tax attorney experience than he and his staff provide. Thank you, Bill, for taking such good care of my clients.
