Jerry Mosbacher


Witnessing a family member’s hospice journey first-hand, Jerry felt a calling to provide this specialized type of care. He was touched by the compassionate care that was provided within the home, but felt he could give even more to patients and their families. As a result, Jerry is fully committed to providing a high level of service and believes in treating all patient families like his own.

John Chung

Medical Director

Dr. Chung believes as much care should be provided at the end of a patient’s life as during that lifetime. While the type of care changes from preventive and curative to palliative, it is no less important and does a great deal to enhance the quality of life at the journey’s end.

In his role as Medical Director since 2005, Dr. Chung oversees the management of our clinical staff, patient care and quality improvement initiatives.

Dr. Chung joined Katy Internal Medicine Associates in 2007. Receiving his medical education in Oklahoma City from the University of Oklahoma’s Health Science Center, Dr. Chung graduated magna cum laude in 1995 with a major in microbiology and a minor in biochemistry. He then completed three years of post-graduate training in internal medicine at Loyola University Medical Center in Chicago, Illinois.

Dr. Chung is board certified in internal medicine with special interests in cardiovascular disease, diabetes, and preventative medicine.

Originally from Brooklyn, New York, Dr. Chung now lives in Katy with his wife and two young children. Dr. Chung is a connoisseur of the fine arts and exotic foods and enjoys tennis, golf, skiing, and ballroom dancing.
