Profile bio

About John Sickman

John Sickman is a Consultant at GLG (Gerson Lehrman Group). He possess expertise in energy, petroleum, procurement, gas, project planning and 45 more skills. Colleagues describe him as "John is a retired oil and gas executive that truly made a difference in Iraqi with the Ministry of Oil. Unlike most USG agencies engaging the Ministry of Oil, John treated them as the client and advised them on technical, business, and strategic matters. He earned the trust and respect of the Minister of Oil and other GOI senior officials. John also paved the way for major regulatory changes in the area of procurement and budget execution for the GOI in terms of allowing the Ministry of Oil to operate as an international oil company, rather than a spending ministry. I have not worked for a more dedicated and engaging person."
