NEWPORT BEACH, CA — MONTH X, 2017 — Alliance HealthCare Services, Inc. (NASDAQ: AIQ) (the “Company”, “Alliance”, “we” or “our”), a leading national provider of outsourced radiology, oncology and interventional services, announced today that Gregg Alan Dickerson, M.D., FACR, FACRO, has joined Alliance Cancer Centers in Greenville and Clarksdale and will be offering radiation oncology services to patients throughout Greenville, Clarksdale and the surrounding communities.

“We are pleased to have Dr. Dickerson join the medical staff of the Alliance Cancer Centers in Greenville and Clarksdale,” said Candi Underwood, Site Administrator for the Alliance Cancer Centers in Greenville and Clarksdale. “Dr. Dickerson is a highly accomplished physician who brings over thirty years of radiation oncology experience to our cancer care treatment team and we are fortunate to have him care for the patients in our centers.”

Gregg Alan Dickerson, M.D., FACR, FACRO, is a board certified radiation oncologist. Dr. Dickerson received his Bachelor of Arts with a double major in chemistry and biology from Indiana University in Bloomington, Indiana, and his medical degree from Indiana University School of Medicine in Indianapolis, Indiana. He completed his residency training in radiation oncology at the Bodine Center for Cancer Treatment at Thomas Jefferson University Hospital in Philadelphia, Pennsylvania, where he also served as Chief Resident.

In addition to his education and medical training, Dr. Dickerson spent 11 years serving our country as a flight surgeon in the Medical Corps of the Air National Guard, becoming a Major before being honorably discharged in 1996.

Dr. Dickerson joined the Alliance Cancer Centers in Greenville and Clarksdale last October as an interim physician.

“After many rewarding and productive years in Denver, Colorado, where I became highly specialized and accomplished for my work treating prostate cancer with radiosurgery, it was time to get ready for the next phase of my career,” said Dickerson. “It was at that time colleagues in the leadership of Alliance Oncology encouraged me to come to the Mississippi to spend some time helping the good people of the Delta. What started off as a commitment for just a few months turned into a desire to continue caring for the dear people here and face the challenges that the spectrum of cancers they develop present. Joining the many other very compassionate physicians in the Delta and employing my advanced skills has been extremely satisfying and ultimately led to wanting to continue my work here.”

Dr. Dickerson has been awarded over ten specialty honors and peer selected honors, including being ranked the number one radiation oncologist in Colorado in 2014 by HealthGrades.com. He also holds both military and civilian honors. He is a member of the American Society of Therapeutic Radiologists and Oncologists (ASTRO), the American College of Radiology (ACR), the American College of Radiation Oncology (ACRO), the Colorado Radiological Society, and the CyberKnife Society.
