Join our team

We're out to run a different kind of firm:

  • We emphasize training and development, to ensure that tomorrow’s legal professionals have the proper skills to be successful advisers, whether in private practice or in-house.   We take staff training, and cross-training, very seriously, as it’s a mandatory condition of employment.

  • We are one firm.   Many law firms, particularly larger ones, are just aggregations of different groups of lawyers. We have structured our firm, including our financial incentives, around the idea that success will be based upon collective responsibility across the entire firm.

  • We work hard, but play hard, too. 

If you are interested in working with us, email us at   We consider part-time and flexible arrangements, and from time to time offer competitively paid internships for current students.
