"

We are truly grateful to Dr. Nasr for his care and treatment of my husband. My husband had a sudden cardiac arrest and was taken to the hospital. Dr. Nasr did an angiogram and placed a stent in his heart. He has been on the road to recovery and his heart function is now great. We are so happy and thankful to Dr. Nasr for all that he did to save my husband's life.

Dr. Nasr is everything I was looking for in a doctor. Kind, open, responsive and spent the time with me to understand my concerns. I have a health care background and he checked all the boxes in what I would hope for myself and my family and patients. Takes the time to understand my individual needs and goals and helped me establish a plan of care that was doable moving forward. I would highly recommend him for any health care needs.
