Terry has worked for two of the world's most influential companies - IBM and Microsoft - in technical, sales, product management and executive positions. She was involved in the information technology industry since 1980 and is a recognized leader in this field, particularly for her communication, management and leadership skills.

At IBM South Africa she was responsible for IBM's PC brands before she left the company to join the newly established local Microsoft organization. She was a key member of the management team that led Microsoft through its massive growth in this country. She started the highly successful corporate sales team, integrated systems engineering skills into major customers, and started up the consulting business. Most recently she was Director of Marketing for Microsoft in South Africa, managing a substantial budget and a large team of specialists. She worked extensively with both IBM and Microsoft internationally.

She was a finalist in the Businesswoman of the Year competition in 2000 in recognition of her role in the industry.

She left Microsoft in 2001 and soon after that joined Gary to help start up BlackStone Tek and bring its products to the market. She is responsible for marketing as well as all operations of the business.

She is passionate about nature and wild life, she's a rose grower and an enthusiastic and experienced scuba diver. She has travelled extensively, and her diving holidays take her to remote parts of the world in search of strange and fascinating marine creatures. Her last trip to Wakatobi (where she celebrated a Significant Birthday) gave her her first sightings of the pygmy sea horses, thereby achieving a long-held dream. Her garden is a place of total enchantment, with 536 rose bushes, luscious lawn, huge old trees, shade gardens, a waterfall and a swimming pool converted into a fish, frog and water lily paradise. The fragrance of the garden hangs in the air all summer. This Garden of Joy is on show to raise money for charity again in October this year.
