The appointment was in regard to the suitability of histotripsy for my cancer. Dr. Ong gave clear, concise explanation of the procedure and how it applies to my case. He answered a myriad of questions and guided me to a solid path forward. Thank you Dr. Ong for the time you took with me. I felt very encouraged after the appointment with the knowledge that histotripsy is a future possibility for treating my cancer.
Swedish Patient
All staff were caring. I felt especially helped in recovery. Dr. Evan is a wealth of knowledge for Swedish and an asset to this country as he has passion for histotripsy. Because of his work, he will be the reason other facilities will look more into this non invasive procedure and better manage cancer !
