As a leading national stop loss carrier, HM Insurance Group sees firsthand the debilitating effects of catastrophic medical conditions. Therefore, in addition to paying millions of dollars in cancer-related claims, the company also focuses its corporate giving initiatives on helping organizations that address conditions that can result in devastating medical expenses.

The Leukemia & Lymphoma Society (LLS) has been a priority charity of HM Insurance Group for more than a decade.

In addition to providing financial support, each year, HM Insurance Group employees volunteer to set up for the organization's Light the Night Walk in Pittsburgh.

"The event brings light to the darkness of cancer by funding research and providing support to those battling the disease," said Carolyn Coleman, regional vice president, Stop Loss Sales, HM Insurance Group. "Cancer is consistently a top diagnosis category in claims that we see exceeding $1 million, so we are happy to help the LLS in their efforts to make a difference."

HM Insurance Group's team of volunteers assembled all of the lanterns that light the walk. They also set up banners, tables, chairs, and tents, and sanitized everything to help make the event as safe as possible for the participants.

HM Insurance Group was a sponsor of the event, and Coleman serves as an executive board member for the Board of Trustees for the Western Pennsylvania and West Virginia chapter of the Leukemia & Lymphoma Society.
