South Street Securities Holdings Inc. (“South Street Securities Holdings”) welcomes Kenneth (“Ken”) McDermott as Structured Finance Treasurer and member of the Financial Control Team. Having first joined the team as a Consultant and now transitioning into Structured Finance Treasurer, Kenneth works on meeting the long-term financing objectives of South Street Securities Holdings’ family of companies, including the execution of strategic combinations with other broker-dealers.

Prior to joining South Street Securities Holdings, Kenneth spearheaded the sale of a privately owned investment company as CFO, led structured credit origination and distribution businesses at Citi, and built and monetized global bank relationships at Société Generale.

Kenneth holds a B.S. in Accounting from Binghamton University. He obtained his CPA license while working at Deloitte & Touche. He is Series 24, 63 and 79 registered with FINRA.

"I am very excited to join South Street Securities Holdings and the opportunity to work with a team of experienced, entrepreneurial and creative finance industry experts. Even more exciting is that South Street Securities is more than a leader in providing institutional clients financing via the repo market: it is growing its equity and mortgage finance franchises; owns patented trading and operations technology platforms (Matrix Applications and GX2 Systems); and, with AmeriVet Securities, is leading the consolidation in the veteran owned broker dealer sector. South Street Securities is poised for exceptional growth both in serving clients financing needs and, perhaps more importantly, building a fintech platform to drive growth across numerous finance industry sectors."
