“Our firm has worked with Dr. Sloan on a number of capacity assessments, primarily for estate planning purposes, and I personally have had the opportunity to have him testify in court about his report and findings. It is obvious that he has a great deal of knowledge and experience in this area and his reports are well laid out and easy to read. In my opinion, he was objective and reasonable when testifying in court. More importantly, he understands his role in providing a medical opinion based on the legal question on which he is asked to opine. I have no hesitation in recommending his services to conduct capacity assessments for medical legal purposes.”
Duncan Magnus, Magnus Law, Langley
