Patient Reviews
Mar 31, 2026
It’s physicians like this man that cause me to lose hope in the medical field today. My dad was ignored, spoken over, and disregarded with every interaction we’ve had with this man. That, paired with the fact that he tried making critical medical decisions on behalf of my dad without even checking the chart/patient notes (or even what was currently hooked up to my dads IV right in front of him!) pushed us to ultimately remove this provider from our care team. It’s very unfortunate to be treated with such little respect and regard from someone who is suppose to be aiding with patient care during someone’s most vulnerable point in life. Would not recommend allowing your loved ones to be treated by this person without your own direct supervision or the patients’ voice will not be heard. Even then, expect a condescending attitude and annoyance if you request any additional details regarding your health plan.
