Adventist HealthCare Shady Grove Medical Center is a 266-licensed bed acute care facility that provides a range of health services to the community such as high-risk obstetrical care, cardiac and vascular care, oncology services, orthopedic care, surgical services, and pediatric care. Opened in 1979 as Shady Grove Adventist Hospital, Shady Grove Medical Center operates as part of Adventist HealthCare, a health-care delivery system that includes hospitals, home health agencies, and other health-care services. 

The doctor’s acclaimed career in medicine began in 1977 when he earned his medical degree from the Albert Einstein College of Medicine in New York City, New York. He then went on to complete his residency in internal medicine at Brookdale University Hospital Medical Center in Brooklyn, New York and his Fellowship in Pulmonary Medicine at the VA Hospital  in East Orange, New Jersey.

The ABIM is a physician-led, non-profit, independent evaluation organization driven by doctors who want to achieve higher standards for better care in a rapidly changing world.

Known for his respectful and polite manner, Dr. Chanales spends his time listening carefully to his patients until he fully understands the nature of their problems, after which he can explain to them what their treatment options are. He does not rush them out of the office until the above is accomplished. He tries to maximize each patient’s well-being, not being satisfied with just “good enough”.
