Dr. Theresa Oppong-Beeko pursued a Bachelor of Arts degree in Political Science and Sociology at the University of Ghana, Legon, and graduated in 1985. Her first business venture after graduating from the university was fishing, however, that business failed and left her with a debt of US$ 2.5 million at the age of twenty-five.

Feeling educationally deficient, she went back to the University of Ghana, Legon where she pursued a master’s program in Business Administration and was declared the Best Marketing Student in 1990. It was there that her passion for constructing buildings was pursued.

In 1994, She established Manet Housing Limited which has built over 1,800 homes since then. Soon, subsequent development projects sprang up. Some of these include: the Manet Gardens, Manet Cottage annex, and the Manet Ville in East Airport.
Her real estate portfolio further expanded to include Manet Palms in East Legon, Manet Court in East Airport, Manet Towers in Airport City, and Manet Paradise in Ada.
In 1998, Theresa Oppong Beeko established Manet Hotels Limited, which acquired a beach Resort at Ada, and developed it into a three-star, 48 room hotel now known as Manet Paradise & Beach resort. The resort boasts of several recreational and leisure facilities such as Aqua sports and marlin fishing.

Out of all her building constructions, the most iconic one is the US$22 million two high rise office blocks in Airport City, known as Manet Twin Towers. The office edifice was commissioned in 2010.

Soon afterward, Manet 3 was in development and was completed in October of 2016. Manet 3 consists of 10 floors with an extended north wing which provides a commercial lease space of 7,600 square meters. The building also houses a 12,000 square meters car park.
