Craig Johnson was a charismatic and magnetic leader — and six weeks after his untimely death, Johnson’s fledgling virtual law firm is feeling the loss.

Andrea Chavez — executive partner and co-founder of Virtual Law Partners in California’s Silicon Valley — left the firm Friday to start Aragorn Law. Chavez said that “no one could fill Craig’s shoes,” and without his leadership at the firm, she decided it was time to try out some new ideas for law practice on her own.
