I went to Douglas guy thinking his years of experience would be beneficial in aiding me with my problems as well as make me feel confident with what he has to say but it did none of that. Im a young guy in decent shape so he decided not to take my concerns seriously. he tried to control the conversation. I had to butt in when I wanted to say something. one of my issues I came to him with was HBP and he asks if I have been taking allergy meds, to which i tell him i haven't for 4 months but he decides not to listen and continue with the allergy meds saying "it could be the reason for my HBP" and I proceed to say 2 more times I haven't taken allergy meds. Then he continues not having any sympathy, saying Im fine and there isn't anything going on (even though I have family history of blood clots). and at the end of the appointment he didn't know I was on HBD meds even through I told the nurse and HIM. I have done 2 tests, it's been over 2 weeks, i haven't heard from them. Unprofessional!
