After graduating from Bowdoin College in Brunswick, Maine, Benjamin was a top salesman and Vice President of Business Development for TransPerfect International, Inc. in New York City.

In 1999, he brought his marketing skills back to Milwaukee, joining fellow Rufus King alumni Aaron Kapp and Joshua Kaiser as co-owner of Rishi Tea.  Rishi Tea had been founded by Kaiser in 1997.  The company owners are proud to have based their successful company in Milwaukee.

Harrison's brand management and business development skills have established Rishi Tea as a leader in the very competitive U.S. tea market. He has placed Rishi Tea in national retail powerhouses, such as Williams-Sonoma and Wholefoods Market.  In the Milwaukee area, Rishi Tea can be found at Outpost Natural foods, Sendik's Groceries, and Sanford Restaurant.

The teas are obtained directly from gardens tended by tea-growing artisans in Asian countries including China, Taiwan, Japan, and India.  Rishi Tea received the "Best Tea" award from the Specialty Coffee Association of America for 2000, 2001, and 2002.  In October, 2004, Gourmet News placed Harrison, Kapp, and Kaiser on the list of "top 20 gourmet stars under 40" to watch.

Benjamin and his wife Kara Sabado live in Chicago.
