He is constantly late, double books leaving you and 1-2 others embarrassingly waiting for the same time slot. His methods are not modern and his awareness of complementary therapies is nil and he is sarcastic about something as benign and proven to be helpful for mental disease such as meditation and yoga. His knowledge his limited to medications. He is a one man show and can be impossible to reach. His voice mailbox is always full. He answers all his phone calls during your session. He is constantly selling his groups which are revolving doors full of people just there for a prescription and you never see them again. He has poor actual theoretical knowledge of group dynamic and group therapy protocols. It's like an easy way for him to make extra money per hour and double bill people for Rx visit and group session . He is disorganized. He promises to call in a med to CVS and never does. He always does "prior authorizations" wrong and blames either CVS or the insurance carrier.
