Karen Barker-Gentile

CEO, President and Co-Founder

Karen Barker-Gentile started her career as a network engineer in Yonkers, New York. But with an interest in online banking and stock trading, the capital markets were never far from her mind. That passion eventually became her career, as she co-founded online broker-dealer SpeedTrader in 1999. Seven years later, the entrepreneurship bug struck again, this time as co-founder of DAS Trader. With more than 20 years of financial accounting, back-office management, broker dealer relations and information technology experience, Karen Barker-Gentile brings to DAS, Inc. a wealth of business and management experience. Further adding to her professional credibility, Karen is one of the few female CEO’s in this male-dominated financial industry.

In 2013, Gentile rang both closing bells of the two largest Stock Exchanges in the World, NYSE and Nasdaq exchanges. These honors were rewarded to her company for having the distinction of the highest level of product service and utilization of the exchanges capabilities. Under Karen’s leadership DASTrader.com is the only service bureau and technology provider to have achieved the highest level of partnership with both exchanges.

Karen understands the importance of building relationships with other companies to provide clients with the best trading experience and strives to maintain those business relationships. She aspires to bring the best experience to her clients and to continue to build and improve her business. She employs hardworking individuals, who will use their skills to offer the best products, customer service, and exchange industry expertise in the business.
