S3 Makes Two Key Appointments
Austin, TX-based best execution technology vendor appoints ex-Schwab employees, Brian Sadlinand and Tobin Griser.

Austin, TX-based financial services software provider S3 has announced two key appointments: Brian Sandlin as the firm’s new senior software engineer, and Tobin Griser as executive vice president. Both appointments are effective immediately.
According to S3 ─ not to be confused with New York-based data analytics specialist S3 Partners ─ the demand for market structure analytics has increased as industry and regulatory bodies look to define the best methods to ensure the most advantageous electronic execution. Sandlin and Griser will be assets in enhancing the firm’s two pillars: trade-monitoring software and unmatched client services.
As senior software engineer, Sandlin will join the software development team in progressing S3’s best execution monitoring products. He will work directly with the client services team toward creating new applications and improving existing platforms, which will allow customers to better manage the demands of today’s market structure.
Prior to joining S3, Sandlin spent 15 years as a software developer at Charles Schwab, helping to build and manage the firm’s StreetSmart Edge Trading Software, Login Microsite, StreetSmart Pro Middleware, and a variety of other applications.
S3 has promoted Tobin Griser to executive vice president of client services. Prior to his S3 tenure, Griser served as a risk manager in Charles Schwab Corporation’s active trader division for equities and options.
