If you're a hard-core holiday hound, you probably already know precisely where every bulb, wreath and plastic reindeer fits in your holiday decorating scheme, right down to the last strand of tinsel.

The less yule savvy of us have waited until the last minute to decorate our homes, inside and out. We might need a few tips from Bob Pranga, whose Burbank, Calif., warehouse full of holiday trimmings would impress even jolly old St. Nick himself.

Would you expect anything less from the man who calls himself "Dr. Christmas"?

"I've raided every grandmother's attic from coast to coast looking for crocheted items, your crafty and vintage items," says Pranga, who has run his Christmas-themed design, decorating and consulting business with partner Debi Staron since 1984.

"We feature all the things you can't do everywhere else, ranging from very high-end ornaments all the way to what you'd find in grandma's toy box or cupboard." Snow globes? Popular and hard to find, but doable. A sleigh? Pranga's got the one used in the Jim Carrey film Man on the Moon. Then there's the infamous tuna-can Christmas tree: nine tuna cans glued together in the shape of a Christmas tree, decorated in green felt.

"Everybody rents the tuna-can Christmas tree," says Pranga.

"That little investment has helped pay the rent on many occasions."

A onetime decorator at Macy's Herald Square, Pranga was responsible for sprucing up the store's Christmas trees. One holiday season, Mia Farrow walked into the store, admired the trees and wished aloud that someone could perform similar magic at her home.

Pranga volunteered.

"I didn't really take it seriously," he says. "I had gone to New York to be an actor, and we essentially worked the Christmas shops. When I met my business partner, we decided to move to L.A., again to be actors."

The Christmas spirit followed Pranga out West. He and Staron found work at Christmas stores in Glendale, Woodland Hills and, ultimately, Beverly Hills, where Kathy Richards Hilton - mom to heiresses Paris and Nicky Hilton - hired him to do the holiday designs for her boutique.

The Hilton connection - and a subsequent appearance on The Anna Nicole Show - widened Pranga and Staron's client list further. Since going independent as Dr. Christmas (a moniker Pranga selected because he was, essentially, on call 24/7 and made house calls), there has been no shortage of business.

"Christmas is a very personal thing," says Pranga. "During the consultation, we sit down with the client and get an idea what it's for. Is it for a party? Is it for the family? Is it just you?"
