Withum is excited to announce that its Orange County office in Irvine, CA, is relocating to a new, larger space just down the street. The new office is located at 200 Spectrum Center Drive, Suite 1700, and is scheduled to open in December 2025.
The new office conveniently remains in the same central business and retail district, providing visitors with familiar surroundings and comparable amenities. Clients, business contacts and team members will appreciate the upgraded, modern workspace within its acquainted business community.
The scenic high-rise office building is in the heart of the Irvine Spectrum business district, providing a larger, elevated in-office experience for collaboration. With panoramic views and outdoor workspace areas, team members and clients can enjoy the natural benefits of working in Southern California. This strategic move continues to leverage Withum’s position within one of California’s business hubs, which is home to many leading tech, education, healthcare, automotive and biotech companies.
Our move to a larger space in Irvine marks an exciting new chapter for Withum in Orange County. We’re excited to offer our team members a thoughtfully and beautifully designed space that embraces modern technology, reflects the unique landscape of the local terrain and makes client engagement even more seamless. This move paves the way for even greater collaboration within our team, with our clients and throughout the community.
