In addition to answering every question, Dr. Sebastian also had recommendations which I had not even considered. Since receiving my cancer diagnosis in December of 2022, I feel Dr. Sebastian is by far the best practioner I have encountered.

Dr Sebastian was very through with explanations regarding therapy. Clear and concise but always in a caring manner he presented risk/benefit of each step and the procedures. He paused after each procedural description to asm if I had questions the patiently answered each question. His calm and caring manner inspires confidence on the part of the patient.
