Common complaints

Rudeness, lack of professionalism, and poor communication from office/front desk staff
Difficulty reaching a live person by phone and slow callback times
Administrative issues including incorrect lab orders and delays in prescription refills
Complaints regarding diagnosis or medical treatment accuracy in some instances

"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."
