Patient Comments (4)
Parker, CO |
Dr Drennen always listens to my concerns and answers all of my questions (and I have a lot). She's one of the few Dr's in the practice that I look forward to seeing because I know I will have her full attention while others are dismissive and pushing me out of the room.
Elizabeth, CO |
Dr. Drennen didn't fully address my concerns or appear that she was concerned with me as a patient. This was apparent in her disregard for asking basic follow up questions that were asked by two other doctors as I sought medical advice and treatment for my symptoms.
in Centennial, Co |
Not very personal and doesn't respond quick to urgent matters. She doesn't make you feel like she really cares about her patients.
in Parker, CO |
I would absolutely recommend Dr. Drennen, but not the staff. I do wish she was still in the old office with the smaller staff and DR list. I always felt welcome there. Since she moved offices it always felt like I was being squeezed in, the staff is less kind and the wait was ALWAYS longer. I dislike being told I am required to see all the dr's in the office, I go to see Dr. Drennen specifically. But Dr. Drennen herself was always great and took plenty of time for all my questions.
