University of Wisconsin


The staff consists of a multidisciplinary team of professionals, including physicians (geriatrician, endocrinologist, and rheumatologist), nurses, social worker, physical therapist and nutritionist, who specialize in treating people with osteoporosis.

Neil Binkley, M.D.

Dr. Binkley earned his MD degree from the University of Wisconsin Medical School and subsequently received his training in Internal Medicine at the Marshfield Clinic. After several years in private practice, he returned to the University of Wisconsin in 1990 and completed a geriatric fellowship. He is board certified in Internal Medicine and Geriatrics. In 1994 he was instrumental in establishing the UW Osteoporosis Clinical Center and the Osteoporosis Clinical Research Program, offering treatment options unavailable in standard clinical practice. Additionally, his research efforts focus on osteoporosis diagnosis, osteoporosis in men and the role of nutrition in skeletal status and the link between muscle bone and fracture risk. Recent studies of vitamin D and sarcopenia (the age-related decline in muscle mass) are lending valuable data to the osteoporosis field. Dr. Binkley is an internationally recognized expert in osteoporosis, sarcopenia and vitamin D. He is past president of the International Society for Clinical Densitometry, on the Scientific Advisory Board of the International Osteoporosis Foundation and Editorial Board for the Journal of Bone and Mineral Research.

Diane Krueger, BS, CBDT, CCRC

Ms. Krueger earned a BS from the University of Wisconsin-Madison and subsequently has been involved with the UW Osteoporosis Clinical Research Program since its inception in 1994 serving as program manager. Since that time, she has conducted more than 50 clinical trials focusing on osteoporosis diagnosis, prevention and treatment. Specific research interests include bone mass assessment and body composition measurement. Ms. Krueger is faculty and Update Committee Chair for the International Society for Clinical Densitometry (ISCD)/International Osteoporosis Foundation osteoporosis and bone densitometry course for technologists. She is currently ISCD Vice President.

Gretta Borchardt, BS

Ms. Borchardt earned a BS from the University of Wisconsin-LaCrosse and subsequently conducted research in genetics, HIV and assay development. She joined the UW Osteoporosis Clinical Research Program in 2012 serving as laboratory manager. Since that time, she has refined the HPLC methodology to measure 25-hydroxy vitamin D and is evaluating the utility of cytokines and proteins to predict bone and muscle status and change. Ms. Borchardt has published manuscripts on genetics, infection and immunodeficiency.
