American Oncology Network Announces Texas as New Operating State with Launch of Community-Based Oncology Clinic

American Oncology Network expands into Texas with the opening of Lone Star Oncology.

GEORGETOWN, Texas, June 12, 2023 American Oncology Network, LLC (AON) announced Texas as the newest operating state with the opening of the community oncology clinic Lone Star Oncology (LSO), which is located at 3201 South Austin Avenue, Suite 315 in Georgetown. The clinic is now open and accepting patients with all types of cancer and blood disorders.

The clinic is led by Board-certified medical oncologist Brian Shimkus, MD, who brings over 20 years of experience in healthcare. He received his medical degree from Augusta University’s Medical College of Georgia, did an internal medicine internship and residency at the University of Virginia Hospital, and completed a medical oncology fellowship at the University of Wisconsin Cancer Center.

“I am eager to continue serving my community not only as a physician but by opening a clinic dedicated to delivering high-quality cancer services to patients in need,” said Shimkus. “We are honored to provide care that is patient-centered and focused on treating the whole person not just the cancer.”

“We are excited to welcome Dr. Shimkus to the network and look forward to supporting Lone Star Oncology and their patients,” said AON Chief Development Officer Anthony Belott. “Cancer takes a toll on patients in many ways. It is our goal to alleviate some of the pressures, and we can do that by ensuring patients can receive the treatments they need without needing to travel long distances.”

LSO is a partner practice of AON, a rapidly growing national network of community-based oncology practices. The network is comprised of Board-certified physicians across the United States who join to ensure accessible and affordable cancer care and therapies are available at a local level to remove the need for patients to travel long distances to receive care and reduce the costs associated with the care received.

AON supports hometown practices, their physicians and patients to ensure the latest in cancer care and treatments are readily available and accessible at the local level. Through the partnership, LSO will provide multiple services to patients such as infusion therapy, centralized laboratory and pathology, oral cancer medications and financial counseling.

“Expanding into Texas is an opportunity for us to continue working toward advocating for accessible and affordable cancer care in these new communities,” said AON Chief Executive Officer Todd Schonherz. “Our mission at AON is to bridge the cancer care gap, and by supporting homegrown practices like Lone Star Oncology, we help patients receive care and treatments in the community they love and know.”
