From beginning to end, Dr. Lee demonstrates confidence, professionalism and expertise beyond his years.

My father was diagnosed of stage IV throat cancer at City of Hope in June 2014. Due to insurance…read moreissue, he had to be transferred to his local doctors for intense radiation therapy and chemotherapy after their tumor board decided on his treatment plan. His health deteriorated but he was able to pull through it all and recovered. A year into his recovery, he tragically started smoking again. His throat cancer then returned and the tumor was growing much more rapidly this time around. His previous doctor referred us to an ENT physician at Riverside Community Hospital. My father and I met with this resident surgeon who conducted himself in the utmost incompetent and uncertain way and advised us that he and and other three resident surgeons would do laryngectomy on my father. My father couldn't even be convinced that the surgery would make him recover again. During this time, my father's shortness of breath worsened everyday to the point he felt suffocated. He was on so many medications and had to carry oxygen tanks with him all the time. It was emotionally painful and unbearable to be around and see him suffer. His conditions worsened and he started to be in and out of emergency room. Eventually ER doctor had to perform tracheostomy and my father stayed in ICU for a week. He was then sent to a rehab center for recovery. Upon his discharge, we managed to find a new ENT doctor, Dr. Carvalho in Hemet. Dr. Carvalho finally referred us to Dr. Steve Lee at Loma Linda University Medical Center for laryngectomy. I wrote all the above because I want people to know that my family has seen a lot of doctors ranging from top notch City of Hope dctors to resident surgeons in community hospital. If you manage to find Dr. Lee at the very beginning in your journey, you should know how truly blessed you are, and you should look no further. It took us a long and painful journey to get to him. In January of 2017, Dr. Lee and his team performed laryngectomy and throat reconstruction for my father. The surgery was a success and my father has since then been cancer free and he is able to speak with his voice prothesis. Everyone in the family including myself thought we were about to lose my dad sometime before his laryngectomy, but he has recovered and started a new life. All of this is because of the beyond exceptional care he has received from Dr. Lee and his team. Dr. Lee is warm and genuinely caring. He's calm, reassuring and pleasant to be around. His humble and down-to-earth character almost makes you feel like he is just a neighbor next door and not a God-like surgeon. After many years being under Dr. Lee's care, it made us realize Dr. Lee is truly one of a kind. He is a top rated surgeon who is driven by his calling and passion as a doctor and he is wholly committed on academic research and striving to provide the best patient care with his team.

Said he has absolutely no idea what's causing my child's pain and said he couldn't even get a scope through her nose bc she has SO MUCH SNOT (repeatedly) and seemed annoyed we were even there when she had symptoms of a cold (she had clear nasal passage when appt was make weeks prior but had a slight nose cold a week before which she was recovering from). Rushed out of the room just as abrasively as he entered. Wow. My child was left wondering why he was so rude and whether she did anything wrong. Waste of time and money.
