GBP paid $42 million for the portfolio, then immediately sued the county for tax overcharges.
Leo Castellano still wears the same frayed cuffs. Maya Torres is now a board member of the Federal Reserve Bank of Boston. David Chen quietly teaches a seminar at Yale Law called “Ethical LLC Structuring.” GBP didn’t just clean the lead and arsenic
