ATLANTIC, IA – Cass Health announced that it is now providing mental health services in its primary care clinic, Atlantic Medical Center, RHC.

“We are excited to further expand our healthcare services for the community, especially in a specialty like mental health where rural areas like ours have a shortage of providers. Adding this service in our primary care clinic also hopefully removes some of the stigma or unease around seeking mental health care,” said Melissa Maas, Director of Primary Care.

After a small construction project to revamp existing space within Atlantic Medical Center, the mental health clinic is now open and seeing patients. The clinical staff is currently comprised of a board-certified psychiatrist, a nurse practitioner, and one therapist.

Dr. Greg Keller is a psychiatrist who completed his undergraduate studies at the University of Montana, earning a bachelor’s degree in Cellular Molecular Biology.  He received his Doctor of Osteopathic Medicine degree from the University of Health Sciences College of Osteopathic Medicine in Kansas City. Dr. Keller then completed his general adult psychiatry residency through the Creighton University and University of Nebraska combined training program, where he earned multiple awards, including Resident of the Year. He is board-certified by the American Board of Psychiatry and Neurology.

Cyndi Wu is a dually certified as a Psychiatric-Mental Health Nurse Practitioner (PMHNP) by the American Nurses Credentialing Center and a Family Nurse Practitioner by the American Association of Nurse Practitioners. She graduated with her Bachelor of Science in Nursing from Clarkson College in 2007, her Master of Science, Family Nurse Practitioner from Clarkson College in 2014, and her PMHNP from the University of Cincinnati in 2026.

Mental Health Therapist Gentri Meier earned an undergraduate degree from Wartburg College followed by a master’s degree from Drake University.
