He previously worked for S3 as a Senior Business Analyst and Product Owner from 2006-2011, during which time he worked directly with existing and prospective customers to identify, define, and implement new software solutions. Mr. Vest rejoins S3 after two years at Hewlett Packard, where he held the position of B2B Online Store Product Manager.

Mark Davies, CEO of S3, commented on today’s news, “We are excited to welcome Jeremy back to S3 in his new role as Vice President of Client Services. His prior experience with us will be invaluable, as he understands our innovative software platform and the dedication to our customers that lies at the core of our business. Jeremy will be a key addition to our Client Services team as our customer base continues to grow, and as we improve the functionality of our best execution analytics and regulatory reporting tools. The customizability of our products is essential for evaluating those factors impacting best execution across the multitude of exchanges and dark pools available in today’s fragmented market, and Jeremy will help to optimize our software uniquely for all existing and future customers.”

S3 has also appointed Rob Olkiewicz, who has over 20 years of experience in client services and information technology roles, to the position of Vice President of Client Integration. Mr. Olkiewicz has worked at S3 for seven years, during which time he has been instrumental in the Company’s growth.

Prior to S3, Mr. Olkiewicz served as Senior Quality Engineer at Dell.

As with Jeremy, Rob’s experience with us will be key as he moves to his new position as Vice President of Client Integration. Rob understands the importance of customizing our services in support of every client’s market structure analysis needs, and will now be focused specifically on the onboarding process to ensure smooth deployment of our software tools for all new customers. 2015 has been a strong year for S3, and we look forward to ongoing success in 2016 as we continue to expand our client base, hire additional staff and enhance our best execution analysis software for both equities and options.”
