With a 15-year gap in her résumé, lawyer Heather Hewitt of Houston was having trouble finding work as a lawyer, even contract work or document review.

But in August, Hewitt starts a year of training and work in the corporate department at Baker Botts in Houston, where she is one of two women lawyers in the firm’s inaugural OnRamp Fellowship class. Hewitt also will receive coaching and professional development with her OnRamp Fellowship, and the fellowship includes a $125,000 stipend.
