Patient Reviews
Apr 09, 2022
i was barely 18 when i was diagnosed with crohn’s disease. immediately after being diagnosed i was put on humira. i had a nurse come out and teach me how to take the shot but the doctor had told me to reach out to her if i had needed help or for any follow up questions. i went to her about a follow up and she screamed at me in the middle of her office. she went into a completely unnecessary rant about personal responsibility and taking my disease seriously. all she succeed was making a very difficult situation worst. making me cry in a room full of people did nothing for me. she is hands down the worst doctor and person i have ever come in contact with.
