Greg Loehr has been active in the options trading industry since 1990 when he first began working for the preeminent proprietary options trading firm Susquehanna Investment Group. Loehr began his career on the floor of the Chicago Mercantile Exchange in Susquehanna’s FX futures and options operation as part of a team supporting five currency option traders, as well as the firm’s traders on the Philadelphia Stock Exchange and the London spot currency trading desk.

His professional training came in the form of game theory, quantitative option theory and pricing, and position risk management, and he spent time training with the firm’s founding partners before going on to trade the firm’s capital for the next three years as an equity options market maker on the floor of the Chicago Board Options Exchange.

Loehr co-founded Third Millennium Trading, LLC with a Susquehanna colleague after leaving that firm in 1996. He continued to trade on the floor of the CBOE and co-managed the firm's trading desk. He also was responsible for training the firm’s market makers to trade the company’s capital.

After eight years as a member of the CBOE, Loehr left the trading floor. In 2004, he discovered his passion for sharing his knowledge with others, teaching options strategy, and has been teaching online courses and weekend seminars ever since. Loehr’s approach to options education breaks down “theory to tactics” as he details the core skills used by every professional on Wall Street into useable and practical details we can all follow. Loehr has taught thousands of students through webinars and in-person seminars throughout the US and around the globe including Ireland, England, Dubai, Canada and Australia.

Loehr earned his J.D. from The John Marshall Law School in Chicago, IL; and he holds the RG146 license from the Australian Securities Investment Commission.
