If I could give a negative number of stars I would. Suffice it to say, Dr. Peter Kohler is one of the worst doctors I've ever met. He was unprepared, uninformed (intentionally, it seemed), unprofessional, not willing to coordinate (or even read reports) from other institutions and professionals (Univ of Michigan). He would poke his head in an exam room and ask the patient what he was doing there???!!! Obviously had not read ANY reports or charts previous to any appointments. His staff seemed equally unwilling to communicate either with other professionals or the patient. Treated the patient with disdain. He should not be practicing. Have attempted to contact Cowell Family Cancer Center to offer positive feedback for future patients - a focus group to look at best practices and coordination of care. The website promises a patient "navigator" to work with a patient through the process - didn't happen. Do have to give kudos to radiology technicians and Dr. Heimburger (radiation oncologist), top notch, friendly, helpful. read more
