Patient Reviews
Jul 26, 2026
Incredibly bad bedside manner. Made no eye contact when he entered, asked why I was there even though the records were sent over from my Dr's office, scared me to death on the seriousness of needing to get my pressure down 100%, even though my Dr. later said that while she knows we need to get the pressure down, it's not a really urgent problem. When I told him the eye drops stung so bad I couldn't tolerate, he said 'they only sting for 30 seconds' completely devaluing my concern. I would never recommend this doctor to anyone.
