Patient Comments (3)
Santa Clarita, CA |
He left my thyroid disease untreated and kept trying to force his private weight clinic. Once I went to another doctor who did the proper tests, I found out that I had no thyroid and thus hadn't been getting proper medication dosage for years. He was also extremely sexist and condescending.

All Dr Charnock is concerned about, regardless of why you are seeing him is your WEIGHT....and how to drop a "little more." When he is "on call", he simply doesn't take patient, Dr., or ER calls, leaving all involved beyond frustrated. Hospital follow ups /rounds are sporadic Totally unacceptable! Office staff stressed & appear angry. Definitely not a positive environment for anyone needing medical care

Displayed cognitive difficulties: drew erroneous conclusions about calorie count on food journal, muttered "idiots" as he struggled to read bloodwork from a lab he doesn't normally use. Re-ordered same recent labwork. Extremely insulting, condescending. Said my weight was twice what should be (which was mathematically incorrect). His nutritional advice was out-of-date and I am concerned his medical knowledge might be as well. Great doctor 10 years ago. I don't trust his judgment now.
