Leadership Team

David Welsh

David is an experienced management consultant. After many years working as a senior manager and Director in big advisory firms like Deloitte, Turner & Townsend and iMPOWER, he set up MainStreet Consulting in 2013. With colleagues there, he has now supported 50+ organisations in Scotland and the UK to make important decisions about their priorities, services, people and budgets – across IT & business support, Public Realm & Place, and in social care.

In 2010, he helped establish a charity providing feeding programmes and other health and counselling services for school children living in poverty in Kenya ( and continues to contribute as a trustee. He is also a voluntary board member of Port Of Leith Housing Association.

He is a Glaswegian-in-exile, living now in Leith with his wife and daughter. Any spare time he has is wasted watching hapless football or buying obscure and often unlistenable records from the 1960s and 70s.

Mark McLintock

Mark has been a management consultant for over 20 years working with Turner & Townsend, ARC and Ernst & Young.  Since joining MainStreet in 2014, he has supported ten RSLs, seven local authorities, five NDPBs, four universities, two health & social care partnerships, two charities and the Scottish Government.

This support has focussed on helping organisations make effective decisions.  This has included helping clients develop business cases, review their strategy, improve services, increase efficiency, consider options, enhance performance, manage change, understand their business environment and mitigate risk.

Since 2010, he has been a voluntary Non-Executive Director at Ore Valley Housing Association, chairing their renewable energy subsidiary from 2011.

Married with two daughters, he lives in West Fife. When not struggling with knee injuries, he is a member of the Scotland over 45 hockey team, a Sunday morning cyclist and the fifth board for Dunfermline Chess Club’s second team!

Corporate Social Responsibility

Here at MainStreet Consulting, we support causes that mean something to us. As we do every year, in 2021 MainStreet gave out several thousand pounds from its Community Fund to a number of local and national charities at Christmas.
