Leadership approach

How I lead teams
and the work.

Strong Customer Success teams need good judgment and a clear operating rhythm. I build both. Teams know what matters, customers understand the value, and leaders can act before small problems grow.

  1. 01

    Understand the account

    Bring customer goals, stakeholders, adoption, and risk into one account plan. Use health reviews and clear ownership to turn that plan into action.

  2. 02

    Make value visible

    Make adoption, risk, and outcomes clear to executives. Strong value stories build trust and support the right commercial decisions.

  3. 03

    Develop the team

    Give team leads and individual contributors practical coaching, clear expectations, and regular feedback. Build standards that help people take ownership and grow.

04

Career progression

From technical depth
to customer leadership.

19+ years across customer-facing technology, including more than 12 years in legal tech and eDiscovery. A career built across support, operations, and Customer Success.
