National Jewish Health PatientDecember, 2017
He is a real nice doctor and takes his time with you. He does not walk in and walk out. He takes his time with you.

National Jewish Health PatientDecember, 2017
I was not given a choice to explain my condition what brought me there. He did not explain his thinking.

National Jewish Health PatientAugust, 2017
Never returned phone calls. Poor communication between _____ provider & doctor office.

National Jewish Health PatientMay, 2017
I would certainly recommend Dr Fenton as long as my patient was assured that she could see Dr Fenton more than once a year

National Jewish Health PatientApril, 2017
No better health care provider.

National Jewish Health PatientMarch, 2017
Rude & condescending - minimized my feelings - would never see him again.

National Jewish Health PatientMarch, 2017
Dr. Fenton is wonderful, kind and caring. But it is very hard to get an appt. with him and a long wait to see him in the office.

National Jewish Health PatientMarch, 2017
Dr Fenton is one of the best care providers I have seen. His diagnosis is top notch and the amount of time he spends with the patient listening all the medical issues with extreme care is phenomenal.
