Of the many doctors I have either met(RN) besides a patient Dr Zazaleh has an office of excellence. Front desk, nurses, Nurse Practitioner, phlebotomist and of course Dr Zazaleh are so kind, knowledgeable, wonderful persons. I am so glad that Dr Bhoopal recommended his cancer care. I have been coming to him since 2009 the past 12 years. He is a kind sweet superbly knowledgeable doctor that I truly appreciate his continued care.

I was diagnosed with colon cancer at 47 years old. Dr. Zalzaleh took time to meet with me and my husband to comfort me and provide insight. He was patient and explained things precisely to us. He took his time, and he truly cared about my concerns and fears at such a frightening time. I would highly recommend him to anyone diagnosed with colon cancer.

My first encounter with Dr. Zalzaleh "closed the deal" as to my comfort level with him as my primary medical oncologist. He showed and demonstrated concern and listening skills, with me, as a first time patient. He truly gives patient care and direct, specific advice as it relates to his patient's medical health issues, follow-up and continuous quality care.

I have been a patient of Dr Zalzaleh's (and his incredible staff) for over 5 years. I have TTP...a rare blood disorder.I will say, in no uncertain terms, I am alive and able to write this review, because of Dr. Zalzaleh!There are far to few Doctors and support staff, like those at Associates in Medical Oncology. (the practice Dr. Zalzaleh is in)
