The People Behind Sustainable Cobourg

Great things don’t just happen on their own. It takes a team of dedicated volunteers to help make Sustainable Cobourg awesome. These passionate individuals give up their time every day to help the community and us. The next time you see one of these people, make sure you stop and tell them just how much you appreciate what they’re doing and ask what you can do to help.

Gudrun “Gigi” Ludorf-Weaver – President / Chair Town Hall Committee

Gudrun came to Cobourg in 2005 from Toronto. Originally from Heidelberg, Germany, she arrived in Halifax, Nova Scotia, in 1950/51 with her family, when she was four. Educated at Blythwood Elementary School, North Toronto Collegiate, and Toronto Teachers’ College, Gudrun continued her education by achieving a Master’s degree from O.I.S.E., and was accepted into a Doctorate program at the University of Toronto. She declined an opportunity to attend The Julliard School of Music in New York as a teenager.

After a forty-three year career in education, having worn many hats, from classroom teacher, to specialty teacher in music, art, drama, special education, French, English second language, swimming, physical education, to workshop leader, editor/writer, and finally as administrator, she decided it was time for a change.

Having been involved in establishing a community organization in Toronto called “Urban Harvest”, Gudrun witnessed first-hand the power of community. With that experience, she felt she could contribute to the newly formed Citizens for a Sustainable Cobourg. This was a wonderful group of enthusiastic Cobourgians who wanted to play an active role in helping to shape Cobourg as a sustainable community. After her return from teaching in China in 2009, Gudrun made a commitment to work with both Sustainable Cobourg and its sister organization, Go Green Together under Judy Smith-Torrie.

Gudrun’s three children are all in Toronto and enjoy visiting this lovely place by the lake with their own children.

Warren McCarthy – ECO Action Advisory Group Lead

2020 will be our 9th year in Cobourg, having previously lived in Clarington near the Ganaraska Forest for 16 years. My last major business adventure was successfully completing the full 15-year cycle of starting, growing and selling a five-person company, Effectivation Inc. We provided business skills training and consulting to improve the quality of selling, servicing, prioritizing and managing.

We trained small businesses via our own ‘public schools’, as well as programs for U of T Continuing Education and the Canadian Association of Management Consultants. We also provided in-house business skills training for larger clients, including IBM, Dell, Royal Bank, Oracle, Pricewaterhouse, Coopers, Bell, KPMG.

Prior to being an entrepreneur, I enjoyed successful career intervals managing sales, service, marketing and operations in large, medium and small firms. Until 2019, I was a volunteer Coach with the ‘Business Advisory Centre Northumberland’ and served on Cobourg Advisory Committees for ‘Planning and Sustainability’ and ‘Downtown Coalition.

I enjoy travel, golf, pickle-ball, reading, thinking and wife & family time.

Advice for business owners: – Success is much more likely by doing good work on the right things than by doing excellent work on the wrong things.
