Our Providers

Portland Diabetes & Endocrinology Center, P.C., in Portland, Oregon, is one of the oldest and largest private endocrinology clinics in the United States. The roots of our clinic go back to the 1920’s when insulin first became available for the treatment of diabetes. Through the years, PDEC physicians have been leaders in the research and advancement of treatment for endocrine diseases. All our physicians are certified as Diplomates in Endocrinology, Diabetes, and Metabolism by the American Board of Internal Medicine.

Radhika Chugh, MD

Scott P. Grady, MD

Born and raised in San Diego, California, Dr. Grady grew up in a pair of shorts. He attended UCLA where he majored in micro and molecular biology while learning some French along the way.  He received his Medical Degree at McGill University in Montreal, Quebec, where he quickly learned that surviving the elements would depend upon long pants!  He completed his internal medicine residency at McGill at the SMBD Jewish General Hospital and next ventured to Boston, Massachusetts for a fellowship in Endocrinology with an emphasis in sleep medicine and clinical research.   Tiring of harsh winters and grant writing he returned west landing in beautiful Portland, OR at PDEC. 

Dr. Grady believes quality medical care is built upon patient education and the patient-caregiver relationship.  Patients are best served when they understand the reason for medical recommendations and treatments.  He tries to convey the scientific background to medical decision making to all of his patients and strives to involve them in all such decisions.  This works best in a collaborative relationship which can only really exist if there is trust.  Trust follows from hearing out and trying to answer the unique concerns of each patient at each visit.  His primary interest is in the management of thyroid disorders including nodular thyroid disease, thyroid cancer and functional thyroid disorders. He also sees patients with the full spectrum endocrine disorders including all types of diabetes.

Like his two greyhounds he is a retired runner.  He remains an avid exerciser by hiking, biking and swimming.  He enjoys cooking Middle Eastern, Persian, Indian, SE Asian, and Mexican dishes and reading fiction and history.  He creates mosaics in his spare time.  He is the chief cook and bottle washer for a beautiful wife, two daughters, two greyhounds and one chicken.

Dr. Neifing attended the University of Illinois in Urbana-Champaign where he received both a Bachelor’s degree in Electrical Engineering and a Master’s in Business Administration. He received his Medical Degree in 1986 from the University of Illinois College of Medicine. Legacy Good Samaritan Hospital in Portland was the scene for his residency with an Endocrinology fellowship following at the University of Washington. He happily returned to Portland when he joined PDEC in 1991.

Dr. Neifing is on the Board of Directors for the Gales Creek Camp Foundation for Children with Diabetes and serves as a supervising camp physician for a week each summer.  He chairs the Endocrine Section at Legacy Good Samaritan Hospital. 

Outside the office he enjoys running, hiking, fishing, golfing (even though his son now out plays him!) with his wife and two teenage children.
