Review of Dr. Kaplon

-Nevada City |

Dr. Kaplon performed my triple by pass 16 years ago. I never had one problem from the time of the surgery. He is also a very kind, compassionate man.

Review of Dr. Kaplon

- in Sacramento, CA |

Dr. Kaplon coordinated the surgery in a week. I went in late September 2017. The initial reason for the surgery was a thoracic aortic graft. During the 6 hour surgery, he also did a triple bypass, repaired 2 valves, and tidied up a few other things. I was in ICU for 2 days, and 3 days in a regular room. There is no pain with this procedure, but I was tired for a couple of weeks. There were no complications. I was happy with everyone involved in this surgery and recovery. Dr. Kaplon is great.

Review of Dr. Kaplon

- in Granite Bay, CA |

Dr. Kaplon recently performed a quintuple bypass for me. Once a competitive athlete, pre-surgery I could not walk to my front mailbox. I should be dead. Dr. Kaplon not only saved my life, at 59 I’m making incredible progress with my cardio. workouts. This doctor has skills that I shall forever be thankful for.

Review of Dr. Morris

- in Murphys, Ca |

Dr. Morris performed open heart surgery and repaired a valve. He has a reputation for excellence and I was not disappointed. Equally outstanding is his staff. Before contacting Dr. Morris I researched the various surgeons and concluded he was the best. I would highly recommend Dr. Morris for cardiac surgery. Bill Carlson, Murphys, CA.

Review of Dr. Kaplon

- in Carmichael, CA |

Dr. Kaplon replaced one of my valves and repaired a second one. Without the surgery I was warned that I only had up to one year to live. The surgery was performed 4 years ago and here I am, my heart getting stronger with every passing day. My heart rate went from 15 to 50. I thank the doctor from the bottom of my heart.

Review of Dr. Kaplon

- in Roseville CA |

Dr Kaplon did my surgery about 7 years ago and I am writing this in great health. He instilled confidence with his first visit the night before the surgery. Going over the what was to be done and could be done. Well it went from a 3 way to a 5 way during surgery. I have finally found a way to recommended him and thank him again.

Review of Dr. Clayson

- in Garden Valley, CA |

Dr. Clayson saved my life twice. He had to amputate my leg to do it, once below my knee, once above. Then I had an aneurysm burst in stump 5 weeks later. I developed bad infection was in hospital for 9 and a half months all total. Dr. Clayson has the best bedside manner of any Dr. I have ever seen. Always very pleasant with the biggest smile. I have now recovered thanks to Dr. Clayson and haven't seen him in quite a while. We developed a friendship seeing each other so much, miss him dearly.
