Who We Are

The scientific team at ADx Healthcare includes physicians, Alzheimer’s researchers, dietitians, and health behaviorists working together to evaluate and implement the cutting edge science on brain health and Alzheimer’s disease.  Our team is committed to empowering patients to address errant metabolic pathways through lifestyle modifications to maximize their cognitive health.

The leadership members of the ADx Healthcare Scientific Team include:

Ryan FortnaRyan Fortna MD, PhD

Dr. Ryan Fortna, MD, PhD, is Board-Certified in Anatomic Pathology with a PhD (University of Pennsylvania) in the molecular biology of Alzheimer’s disease. He oversees the Molecular Pathology lab at Northwest pathology laboratory testing facility and serves as the Chief Science Officer at ADx Healthcare.  Dr. Fortna is interested in helping patients better understand their risk for Alzheimer’s disease so they can make lifestyle modifications that may help overcome the risk inferred from a deleterious genetic variant.

Marci Hardy PhD  

Dr. Marci Hardy, PhD is the Director of Health Sciences for ADx Healthcare. Dr. Hardy has experience in outpatient rehabilitative care, hospital and corporate wellness and preventive programs, scientific research, and academic leadership and instruction. Dr. Hardy’s role is to develop patient education materials and informative, user friendly patient reports to address Alzheimer’s disease genetics and the modifiable risk factors of cognitive decline. Dr. Hardy also is a member of ADx Healthcare’s Scientific Team as well as being actively involved in the local Alzheimer’s community as both a speaker and volunteer. Dr. Hardy strives to help empower individuals to understand their risk for Alzheimer’s disease and take control of their cognitive health by living a brain healthy lifestyle.
