In five years, Washingtonians won’t be able to make it from the front door to the office elevator without bumping into a Dunkin’ Donuts for a caffeine fix.

The doughnut company, which went public earlier this year and is owned in part by the Carlyle Group, has begun a 60-store expansion in the Washington market in a push to grab some of the caffeine crowd from rivals such as Starbucks and McDonald’s.

Dunkin’ plans to boost its number of stores from its current 125 to nearly 200.

But does D.C. really need more coffee?

There’s lots of room for expansion, argued John Dawson, the donut, er, coffee company’s chief development officer.

“We are all about coffee,” said Dawson. “We are a beverage company through and through.”

He said the company loves D.C.’s market for its household income and its population density. But Dawson really gets a morning rush from the potential in the white-collar workforce looking for its caffeine buzz.

Compared with Philadelphia, which has 530 Dunkin’s feeding 7.9 million people, Washington’s 6.7 million only has 125 from which to feast.

In addition to traditional locations, the Donut company, which is emphasizing its new healthier food offerings like its “Egg White Veggie Wake-Up Wrap,” is looking to install kiosks in office buildings and drive-up stores in strip centers.

Dunkin’ already is everywhere from the Pentagon, FBI, Verizon Center and a slew of agencies from the Energy Department to the Securities and Exchange Commission.

A lesson in expansion

Rockville-based Peer2Peer Tutors is growing.

Founder Erik Kimel, who started the company his senior year at Churchill High School in Potomac, is opening offices in New Jersey, Connecticut and North Carolina as well as a new online tutoring option.

Kimel finds top high school students to tutor customers, which range from kindergarteners to seniors in high school.

Peer2Peer has created more than 3,500 jobs, served more than 5,000 students, and provided more than 50,000 hours of tutoring services since its start in 2004 with a $50 stake by Kimel.

Peer2Peer expects revenue of nearly $1 million in the 2011-2012 school year. Kimel has no debt and no investors, and he funds all growth out of profits.

No mystery to this plot

Morgan Stanley Smith Barney money adviser Marvin McIntyrehas penned a novel called “Insiders.”

The big-time money man, whose grandfather was a city editor at The Washington Post and a personal secretary to FDR, drew on his 40 years in the investments business.

“All my life I wanted to write a book, but I couldn’t find a plot,” said McIntyre, who is rated by Barron’s as one of the best wealth advisers in the United States. “If you couldn’t find a plot in 2008 in my business, then you weren’t paying attention.”

The Buzz caught up with McIntyre after a busy week. He started it off at the Carlyle Group’s annual investor conference, then headed to Orlando for a Barron’s gathering of top money managers.

McIntyre used an independent pubisher to save him a couple of years in the editing process. The advice came from friend, bestselling author David Baldacci.

While we had McIntyre on the telephone, we couldn’t resist asking for some investing advice.

“Stocks are undervalued,” said the Potomac resident, who once had a 10-minute finance/sports spot on WTEM with Doc Walker.

The book’s proceeds are going to charity.
