About Tamara Hall

➥ I am a strategic, driven, and focused leader with a seasoned vendor management background, a history of negotiating highly competitive contracts, and a talent for aligning teams around common goals. I combine over 3 decades’ experience directing all vendor management, contracting, and service delivery management efforts for multiple high-profile organizations; holding vendors accountable against all SLA and KPI goals; managing a suite of projects and strategic initiatives to enhance organizational agility and performance; and carefully shaping the processes and policies that sustain an efficient, productive, and highly competitive organization.➥ I am a supportive team leader with a strong ability to take charge of projects, train and empower others, and motivate those around me to do their best work. I believe a leader’s primary duty is to cultivate, professionally develop, and inspire her team. I have the ability, expertise, and coaching skills to drive my team to success.➥ I am an agile thinker who is highly adaptable and quick on her feet. In today’s rapidly evolving vendor management space, what worked yesterday may not work tomorrow. I have the experience and the dexterity to stay one step ahead of change, shift gears when the context calls for it, respond effectively to evolving industry trends, and drive my organization to success.➥ I have the communication skills to clearly articulate my vision, persuade people to take action, and get the ball rolling in the right direction. Whether I’m sending out emails, communicating with a team member, presenting to a crowd, or anything in between; I communicate quickly, accurately, and effectively.
