Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

We are so happy with the care I received. The Dr and the PA were both there and gave great care.

Dr. Siegenthaler saved my life. He preformed emergency AAA surgery on me January 2, 2021. Dr. Siegenthaler closely monitored my progress during my 36 day stay in the hospital (14 in ICU) and was involved in my care during the subsequent months of rehab . In addition to his surgical skills, he is both compassionate and empathetic. 5 Stars aren’t enough.

Quadruple Bypass
I was rushed to the emergency room with chest pains on 12/19/2020 and had a massive heart attack. It was determined that I would need a quadruple bypass. Dr. Siegenthaler was my assigned surgeon for which I am so thankful for. He saved my life twice!! He is an outstanding surgeon and has so much empathy and compassion for his patients. I love this man and can’t thank him enough.

A Blessing
I was rushed by ambulance from a rural hospital to an urban hospital where Dr. Siegenthaler works. I consider it a miracle that my surgery was performed by Dr. Siegenthaler. I believe he saved my life. His experience and confidence in thoracic aorta surgery is what I needed.

He is an outstanding surgeon, and I would highly recommend him. Actually, I think he's pretty awesome. He successfully performed a life-saving operation on my husband, for which I am eternally grateful. I wish I could give him more than five stars; it truly doesn't seem enough. In addition to his skill, he has an excellent bedside manner and is really good at explaining the process in language that is easy for anyone to understand.

Dr. Siegehthaler is an excellent surgeon, highly skilled and experienced in the most complex of heart surgeries. One could not be in better hands when open-heart surgery is called for.
