By Laura Hayes After a multi-year process, Green River Cannabis held a soft opening for its new Hopedale location on Feb. 21. Green River Cannabis is a family-owned business run by the father-son duo of Constant and Ryan Poholek with assistance from Ann Poholek as administrative coordinator of both facilities. Constant Poholek said they were “extremely excited” to open the new dispensary. “We’re going to have exclusive hours with exceptional deals,” he said.
