Ratings & Reviews
How was your appointment with Dr. Diener?
Dr Diener took care of my Mom who had Idiopathic Pulmonary Fibrosis for years. I can't comment on medical treatment since not an expert. Based on decades of health care experience, I can say with no doubt, he really impressed me with how patient, caring, empathetic and genuine he was. Everyone in his office was so helpful, caring and I truly thank you all. She died in hospice care, during a covid spike, in immediate area and community. It was not official yet covid was also not ruled out since homebound on oxygen in hospice so they did not even test her and others were positive. This, in my opinion, was a traumatic failure to protect her, my family, friends, other patients, their employees and community. So unfortunate Dr Diener retired. I know under his care her quality of life, longevity, safety, and death would have been much more ideal and my grief so much less. She chose and trusted him and I understood why. Thank you for being her phenomenal caring physician Dr. Diener.
