Arborist Expert Witness, Court Testimony & Trial Preparation

William “Doc” Pickhardt is well known by the legal profession for his forensic skills. Over the years he has surrounded himself with other experts which he calls on, if needed, to assure the best possible result. As an expert he directs the attorney down the appropriate path so as to gain the best outcome for the client. In trial his expertise is unsurpassed and judges and juries learn to respect his testimony early on. He has been instrumental in successful outcome of over 100 cases from simple trespass to accidental death. Recently, new case law was written by the Oklahoma Supreme Court based on his report concerning an accidental death in the Tulsa area.
