Santa Clara-based SVB Private Bank added two senior managing directors to its wealth management arm. Natalya Alexei and Vishal Wadhwa joined a team of 12 advisors that also includes four advisors who moved from Northern Trust following SVB Financial Group's purchase of Boston Private in July. Alexei and Wadhwa deepened the firm's expertise serving high and ultra-high net worth clients, notably in technology, life sciences, and venture and private equity. Both formerly led the UHNW private banking business for Northern California and the Pacific Northwest for Wells Fargo Private Bank. Argent Financial Group appointed Kathleen Plate as vice president and audit manager in its San Antonio office.
