Common complaints

In patients' words

"The office staff that I've dealt with are rude, incompetent and need training in professionalism and how to do the job. ... so, if you can put up with a bunch of idiots at the front desk and micromanage them to do a task for you, Dr. Z is well worth seeing."

LocalityBiz user review

"Dr. Carnell is a highly skilled and professional doctor. He is very thorough and caring. My only complaint, is how I can never get a live person on the phone when I call the office."
