Description We are looking for a highly organized Sr. Administrative Assistant to provide part-time, in-office support for a wealth management team in California. This Contract position is well suited for an experienced, detail-oriented candidate who thrives in a client-facing environment, manages competing priorities with care, and helps maintain smooth daily operations during a period of team growth and onboarding. The ideal candidate brings strong administrative judgment, attention to detail, and the ability to work closely with advisors and internal partners while supporting a high standard of service.
Responsibilities:
  • Coordinate administrative and client service activities that keep daily office and advisor workflows running efficiently in a part-time, on-site setting.
  • Assist with new client setup, account updates, transfer requests, and related service tasks by preparing and organizing required paperwork for accurate submission.
  • Handle transaction-related documentation for items such as wires, checks, journals, and distributions while maintaining a high level of accuracy and timeliness.
  • Maintain complete and well-organized client information within CRM and custodial systems to support reliable recordkeeping and follow-up.
  • Prepare materials for client and internal meetings, including agendas, reports, scheduling support, conference call logistics, and post-meeting action tracking.
  • Review account notifications and routine service matters, resolve straightforward issues, and direct more complex items to the appropriate operations, compliance, or leadership contacts.
  • Support document retention and regulatory file practices to help ensure records are current, accessible, and compliant with firm standards.
  • Work collaboratively with advisors and cross-functional partners to strengthen service delivery and identify practical improvements to internal processes and the client experience.
  • Arrange travel and provide general executive-style administrative support, including calendar coordination and communication follow-through as needed. Requirements
  • 1-3 years of experience in administrative support, client service, wealth management, financial services, or a closely related environment.
  • Strong verbal and written communication skills with the professionalism needed for client-facing interactions.
  • Demonstrated ability to stay organized, manage multiple priorities, and follow through consistently on time-sensitive tasks.
  • Proficiency with Microsoft Office and comfort learning or working within CRM platforms and other business systems.
  • Sound judgment when handling confidential information and sensitive client documentation.
  • Ability to work independently while also contributing effectively within a collaborative team environment.
  • Familiarity with wealth management is required.
  • Experience supporting calendars, travel coordination, meetings, and general administrative operations is highly valued.
