Dr. Birhiray is a wonderful doctor. He is an expert in the cancer field where he had and continues to have numerous professional research experiences in oncology. He works at educating his patients by inviting them to attend research study oncology conferences in an effort to gain the latest knowledge related to their conditions. His care and compassion are second to none. He always greets his patients with a warm, friendly smile. He is a kind person with an infectious laugh. Dr. Birhiray listens to his patient’s concerns, provides immediate assessments and results. Afterwards he seeks their input in attempting to determine treatment and/or solutions. Dr. Birhiray has cared for me for a number of years and I can say with a doubt that my health has improved tremendously as a result of him being my oncologist. Thank you doctor.
