Prior to this, Patrick was Executive Vice President, Strategic Implementation for Rosenthal Collins Group. In that role, he is charged with spearheading important initiatives designed to enhance RCG clients’ experience and foster continued innovation. He joined RCG in 2002 as a runner on the Chicago Board of Trade’s grain floor and has been part of the team ever since. He was one of the first employees on the eHelp Desk and eventually took over management of all 24-hour electronic trading support operations and execution services.

As his role within the organization continued to grow, Patrick assumed the role of Senior Vice President of Operations in 2015. In that position, he led coordination between clients, vendors and exchanges on a variety of industry initiatives including market data reporting and pre-trade risk management. In keeping with the firm’s focus on high-touch service, he helped initiate its Risk Electronic Limits Management System (RELMS), an RCG offering enabling its broker community to manage pre-trade limits across its most common trading software.
