“We congratulate Val and Nori,” said William Tyree, Managing Partner. “They both contribute unique skills, deep industry knowledge, and an unrelenting drive to deliver results for our clients. We are delighted to welcome them into the Partnership.”

Valentino Carlotti joined BBH in July 2020 as a Partner-Elect in the Private Banking line of business. On September 30, 2020, Val succeeded Carter Sullivan, who retired at the end of 2020, as Head of BBH’s Corporate Advisory and Banking practice. In this capacity, Val leads our effort to help private business owners achieve their financing, business growth, wealth planning, and family goals across generations of ownership. Val brings two and a half decades of business development, markets, corporate finance, M&A, and relationship management leadership experience to his position at BBH. Most recently, Val served as the Chief Business Development Officer at Sotheby’s, where he was a member of its Executive Management Committee. Prior to joining Sotheby’s in 2017, he was a Partner at Goldman Sachs where he worked for 23 years in various roles in Investment Banking, Institutional Equities Sales, Client Relationship Management, and Human Resources across Goldman's offices in the U.S., Europe, and as President of Goldman Sachs Brazil. Val resides in New York.

Noriyasu Sonobe joined BBH in 2007 and is currently co-Office Head of BBH Tokyo, as well as Head of Relationship Excellence for Investor Services in Japan. He began his BBH career in Tokyo as a Senior Client Service Manager. Since then, Noriyasu has held a variety of leadership roles in Service Delivery, he launched our Japanese client service team in Boston and ultimately, he became Head of Service Delivery Tokyo. Over the last five years, Noriyasu has been instrumental to the expansion of our cross-border business for Japanese institutional investors. In 2017, he transitioned to Relationship Excellence from Service Delivery and became the head of that discipline for our Japanese business. Beyond his responsibilities in Investor Services Tokyo, Noriyasu is also responsible for BBH Investment Services Japan, our Investment Management subsidiary. Noriyasu resides in Tokyo.
