American Oncology Network and Messino Cancer Centers Welcome Neuro-Oncologist Jeanette Pueschel Larson, MD, to Physician Team

Dr. Jeanette Pueschel Larson joins the practice as the newest physician.

ASHEVILLE, N.C., April 3, 2023 Messino Cancer Centers (Messino), partner practice of American Oncology Network, LLC (AON), announced the expansion of the medical team to include Board-certified neuro-oncologist Jeanette Pueschel Larson, MD. Dr. Larson is available to see patients at the Asheville clinic starting today.

“We are excited to have Dr. Larson joining our physicians’ team here at Messino,” said Martin Palmeri, MD, MBA, Board-certified medical oncologist at Messino. “Our goal is to provide comprehensive cancer care and therapies so that we can better serve our patients and their unique needs. Dr. Larson’s specialty is of great value to us and our patients. Welcome, Dr. Larson to the Messino team.”

Dr. Larson earned her medical degree from Dartmouth Medical School and went on to complete a residency in neurology and a fellowship in neuro-oncology at the Barrow Neurological Institute of St. Joseph’s Hospital and Medical Center in Phoenix, Arizona. She then completed a working fellowship in neurological rehabilitation at Valley Physician Medicine & Rehabilitation in Phoenix, Arizona. Through her extensive education and training, she is experienced in caring for patients with aggressive brain, spine and nervous system tumors.

“I am passionate about providing patient-first care that is evidence-based and being an advocate for my patients and their families,” said Larson. “Messino Cancer Centers practices patient-first care continuously through every interaction and decision made. Joining the Messino team is an honor, and I look forward to helping them elevate cancer care in the community.”

Messino is a partner practice of AON, a network of community-based oncology practices across the nation. The partnership grants the practice access to a variety of critical support services and resources, such as an in-house specialty pharmacy and financial aid assistance for patients, so that physicians are alleviated of the burdens that come with running a full-time practice and can focus on patient care.

“Messino joined AON in January 2020, and it has been our pleasure to support them as they have continued to grow and expand their physician team,” said Dr. Stephen “Fred” Divers, AON’s chief medical officer. “We are excited to welcome Dr. Larson to AON and look forward to her contributions to Messino and the network.”

“Dr. Larson is a wonderful addition to the Messino team,” said Todd Schonherz, AON’s chief executive officer. “She exemplifies the patient-first care approach that we are proud to offer across all of our practices, and her specialty in neuro-oncology will help the practice provide more tailored cancer care to patients who, unfortunately, are facing these types of tumors. Congratulations to the practice for expanding their team.”
