Nov 06, 2026 Closer to Home: Jeff Vinsonhaler Opens TSG’s New Grass Valley Office
TSG Wealth Management is opening its doors in Grass Valley, welcoming Jeff Vinsonhaler as a Managing Director, joined by Senior Client Associate Millie Sigala, to lead the practice’s new office, with a by-appointment location in nearby Yuba City. With nearly 30 years of experience and deep roots in the region, Jeff brings a highly personalized approach to wealth advisory, and the new office brings TSG closer to the communities he calls home.
A Yuba City native, Jeff relocated to Oregon in 1989 to attend the University of Oregon, where he earned a double major in Business Management and Psychology. He entered the industry in 1994 and began his career as an advisor with Dean Witter in 1997, returning to California in 2008 and spending the decades since growing his practice across the region. Today he serves clients throughout California, Oregon, and beyond.
Jeff specializes in the development and implementation of long-term, tax-efficient investment portfolios, with a focus on tactical asset allocation and retirement income strategies. His work spans trust accounts, IRAs, college savings plans, annuities, securities-based lines of credit, and life and long-term care insurance.
“I chose TSG because of the support and resources behind it,” said Jeff. “This platform lets me deliver an even more elevated, client-focused experience than I could before, and that is what my clients deserve.”
This move was a deliberate one, drawn by the enhanced support and comprehensive resources of a nationally recognized practice. For Jeff, it was also a chance to build something in the community that shaped him.
“Opening an office in Grass Valley means continuing to serve the community I call home,” said Jeff. “I grew up in this region, and being able to build something here for my clients is deeply meaningful to me.”
TSG Wealth Management supports over $21 billion in assets under management across a team of 184 professionals operating out of 28 offices throughout the western United States.*
“Jeff has spent nearly three decades earning his clients’ trust, and he does it the way we believe in, one relationship at a time,” said Mark Schulten, Managing Partner of TSG. “Opening our Grass Valley office with an advisor so devoted to the people around him makes the moment even more meaningful.”
Jeff’s arrival also brings a depth of technical expertise to the new office.
“Jeff builds thoughtful portfolios designed to carry clients through retirement, and that discipline is exactly what families planning for the long term need,” said Allen Schreiber, TSG Partner. “He brings real technical depth to everything he does.”
The Grass Valley opening marks another step in TSG’s measured expansion across Northern California.
“Grass Valley is a wonderful addition to the TSG family, and Jeff is the right advisor to lead it,” said Brian Borst, TSG CEO. “Expanding into the Sierra foothills with someone so rooted in the region is exactly the kind of growth we are proud of.”
With Jeff and Millie now in place, TSG’s Grass Valley office opens its doors with a local team clients know and trust, and the full support of TSG behind every plan.
