Dr. Thaker received his undergraduate degree in biology with summa cum laude from The College of New Jersey and his medical degree with junior Alpha Omega Alpha status from Rutgers University – New Jersey Medical School. He received both degrees through the highly competitive 7-year accelerated combined medical program. During medical school, Dr. Thaker helped develop novel therapeutic combinations for brain tumors and was awarded a clinical research fellowship through the Doris Duke Charitable Foundation at the University of Pittsburgh Medical Center.

Upon graduating medical school, Dr. Thaker completed a transitional internship at the Crozer-Chester Medical Center, where he worked with leading community doctors in general medicine, obstetrics, gynecology, and pediatrics. He then completed residency training in Radiation Oncology at the prestigious University of Texas MD Anderson Cancer Center in Houston, Texas - the #1 ranked cancer center in the country by US News and World Report. In an effort to improve the quality of cancer care in patients’ communities, Dr. Thaker also completed a fellowship in healthcare management, where he worked with national leaders in quality improvement and healthcare innovation at the MD Anderson Cancer Center and the Harvard Business School on innovative cancer care delivery initiatives.

During residency, Dr. Thaker worked with leading experts in all aspects of radiation oncology and has helped develop cutting-edge cancer care therapies. He has expertise in treating a wide range of cancers, including breast, lung, head and neck, gastrointestinal, gynecologic, genitourinary, and central nervous system malignancies. 

A committee member of the American Brachytherapy Society, Dr. Thaker worked with fellow committee members to develop a prostate cancer awareness webpage to help prostate cancer patients better understand all of their treatment options. 


I have a strong devotion to community-based cancer care, and I strive to bring the highest quality of cancer care to patients living close to their homes. I am deeply passionate about helping patients and their families through their fight against cancer, and I believe in patient-centered care, where I combine each patient’s personal values with strong multidisciplinary collaboration and the most cutting-edge standards of cancer care. I constantly strive to maximize the effects of treatment while minimizing side effects, and I work tirelessly to communicate with patients, families, doctors, nurses, and staff throughout their cancer care. Through Arizona Oncology and The US Oncology Network, I am able to bring the latest advancements and clinical trials to patients who need them most. 


In addition to his devotion to community cancer care, Dr. Thaker enjoys swimming, running, biking, hiking, traveling, watching movies, and singing Bollywood songs. He especially enjoys spending time with his wife and two young children.
