Commercial real estate boutique Pursley Friese Torgrimson has disbanded—a victim of its own success, the firm’s principals said.

The close-knit boutique, which provided an in-house nanny for the children of its 12 lawyers and staff, had reached a point where it needed to get much bigger or become part of a larger firm, said co-managing partners Stephanie Friese and Christian Torgrimson, who are both joining much larger out-of-state firms.
