Always feel like Dr. Snell is tuned into me and concerned.

Dr. Snell is a caring person as well as an excellent doctor!

I LOVE Dr. Snell and the care she provides. HOWEVER, there's a big issue. Dr. Snell gives me numbers from my blood work orally. When I return home, my husband ALWAYS (out of genuine concern) asks for good cholesterol and bad cholesterol numbers as well as many other numbers from the blood panel. I simply can't memorize all the numbers (and they have no meaning when I can't see what the numbers ideally should be). Once I asked Dr. Snell for a printout. It was many pages long and was gobbledegook. My husband wants me to find a new doctor at Aurora where, as a matter of course, you are presented with a concise list of numbers. I'm looking into it!

Wait time was wayyyyyy to long.

Dr. Snell is a superb Doc. She is a caring, concerned person, and I have the utmost confidence in her as my physician. She always spends as much time as is necessary to be sure I understand everything she is telling me. I credit her 100% for my quitting smoking and drinking. She actually brought me back from the dead several years ago, when I had an adverse reaction to a pneumonia shot at her office. She is terrific!
August 13, 2016
