October 1, 2018 7:00 PM

My visits with Dr Dancui are always awesome. He is a great doctor. His CNA and Nurses are the best.

August 24, 2018 7:00 PM

Dr. Dancui took the time to not only check my heart but he asked me what other issues I might be having. He talked with me about them. He actually had my last few lab results in his hands and was able to flip back and forth comparing them. This led him to eliminate some of my medications that were detrimental to my new condition and add another. He took his time and I appreciated that. Before I left the room his nurse scheduled a follow-up appointment. I was extremely pleased with his thoroughness and concern.

June 24, 2018 7:00 PM

Wonderful visit, explained every thing and gave good advice. Encourage you to live a healthy lifestyle.

May 30, 2018 7:00 PM

The 'fellows' reaction to my echo? was alarming and unsettling. Danciu's reaction was very matter of fact & I felt both of them gave me a diagnosis but not a prognosis. Was my situation critical? What does this diagnosis mean to my quality of life? Does it affect my general health? Ok, so my meds are changed. What are side effects of the new meds? Specifically & not generally. I called the next day with more questions. His nurse called the next day and (actually I asked question on the portal) answered my question. I called later, another day and asked for a written recap of the answers. She asked if I had a pen and paper. I wasn't home so I didn't. "Well, this is our usual procedure and seems to work for most people." It does not work for me. Honestly, the constant turn over in this practice does not inspire confidence. There's always new staff. For a cardiac patient to have to wait 2 months to get an appointment is concerning. Why have the internet portal for communication if getting a written recap is so difficult. Hire a scribe! When two grim faced physicians tell you your cardiac status has changed one doesn't always think clearly or ask all the right questions in the moment or remember them accurately. Written documentation by the physicians office helps e be sure I am on the right track and understand new issues.

May 30, 2018 7:00 PM

I was one of the best visits I had in a long time. Dr. Danciu is concerned about me since I suffered the heart attack back in December of 2010. And so am I!

May 30, 2018 7:00 PM

Thanks you for service God bless America.

May 22, 2018 7:00 PM


May 13, 2018 7:00 PM

this was an annual follow-up and went well. I I like Dr. Danciu very much and have been very please with my care. Results of my blood test were not shared by this office because the test was taken at my GP's Office and they shared the results with me and I took the results to this office myself.

May 6, 2018 7:00 PM

I have been going to him quite a while.

April 28, 2018 7:00 PM

my provider keep me inform about my health problems. and concerns about my medicine.

April 23, 2018 7:00 PM

My experience is always great with Dr Dancui. His team X and others are the best.

March 31, 2018 7:00 PM

I go every six months for check-up. Dr. Danchu is very understanding and easy to talk to

March 21, 2018 7:00 PM

During this visit, I was treated with courtesy and respect. Clerks and receptionists were helpful and nice. Dr. Danciu Sorin is very good and professional doctor.

March 20, 2018 7:00 PM

He is a wonderful doctor. Very thorough and aware of my worries & needs & and kind.

March 12, 2018 7:00 PM

December 22, 2017 6:00 PM

I don't my being seen by the physician's colleague. This time it was a "fellow." Dr. Danchu is busy but always takes time to help me understand what is going on and I appreciate that.

November 27, 2017 6:00 PM

This was the second time that I have seen Dr. Danciu. He was informative and encouraging.

November 27, 2017 6:00 PM
