@ha Moment

When Bruce decided to start the firm in 1991, three weeks before our wedding! He had no doubts, but it was a little scary as we were just starting our family. Since then, I have watched the investment wisdom, entrepreneurial spirit and tireless commitment to clients that has made TWM a successful family firm. TWM is a family—not just the employees, the clients are members of the family too.

She has served as a Girl Scout leader and PTO president. Marianne enjoys gardening, cycling, hiking with her beagle, traveling, and generally having fun with her family. Current obsessions include Freakonomics podcasts, uAspire, the Michael J. Fox Foundation, peonies, orchids, the Light We Cannot See, her twin niece and nephew, and Santa Barbara.
