By 1976, 635 Main Street had expanded to include treatment space, offices, and even an apartment for the occasional homeless patient to crash in. When the opportunity presented itself to buy the building, Masselli, Matt Vinikas, and John Hickenlooper scraped together $10,000 for a down payment on the $40,000 purchase price. Of the three, Masselli had no money of his own: his part of the down payment was paid by credit card.
