Our Team

Born and raised in New Jersey, Jonah Bruck moved to Chicago in the mid-1980s.


With almost no money, he started a wholesale Health & Beauty care business and, within 4 years, he employed over 46 employees and became a major player in the Chicago market. 10 years later, one of Jonah’s few competitors bought out the company for an undisclosed amount.


In the late-1990s, Jonah Bruck partnered with Lennie Weiss and formed Olympia Group, which aimed to enter the skilled nursing home business. Jonah was key in handling all the operations, as well as looking for further opportunities to grow the business.


Within 8 years, Olympia Group became the 4th largest nursing home provider in the state of Michigan, as well as the largest in the Detroit Metro market.


After 20 years of partnership, Jonah Bruck and Lennie Weiss sold their facilities, but still maintain an equity interest in the new entity.


In addition to Olympia Group, Jonah Bruck and Lennie Weiss have successfully launched an additional company, Diamond Rock Properties & Investments, which invests in real estate and other opportunities. Today, Diamond Rock Properties & Investments has a multitude of investments across the United States.
