The Hahnemann Bariatric Surgery program is participating in the Philadelphia Light the Night Walk in support of Andres Castellanos, MD, who has been battling leukemia.

Light the Night events take place around the country, and fund treatments that are saving the lives of patients today. The Leukemia & Lymphoma Society is making cures happen by providing patient support services, advocating for lifesaving treatments and pioneering the most promising cancer research anywhere.
