Meet The Team

Bringing jobs and IT training to Tulsa, OK and beyond since 1995.

Who We Are

More than a company, OakTree is a family. Since 1995, our account managers, training managers, recruiters, and administrative staff have maintained close relationships with clients and specialists every step of the way. Everyone is on a first-name basis and loves helping teams, clients, and job seekers thrive.

What We Do

Simply put, OakTree helps companies and job seekers achieve their goals more efficiently. Whether the need is to land a coveted position, fill a crucial role, sharpen a team’s technical skills, or help manage contractors, consider it done and done professionally. OakTree has your back.

Why We Do It

There are few better feelings for us than calling an applicant to ask, “when can you start?”, telling a client “we have the perfect person for that position”, or hearing “that class has helped us so much.” You’re already great at what you do —  we just want to help you be even better.

Proud To Be A Woman-Owned Business

Lisa Wilson - President, Owner

With a unique talent for motivating her team as well having a notable technical savvy, Lisa has been integral to the success of OakTree since day one. After graduating Oklahoma State University in 1986 with a Bachelor's in Computer Programming and Information Science, Lisa started her career as a computer programmer with Amerada Hess. After working as a Senior Systems Developer for Williams Energy, Lisa was part of a four-person team that founded OakTree Software, Inc. in 1995. Seven year later, Lisa became the sole owner and aimed to build a successful company that was conducive to the family lives of its employees. Because of her leadership, OakTree has not only made it through instances of downturn in the economy, but did so in a way worth meriting the company's addition to the list of 25 Best Small Companies To Work For in the nation by Working Mother Magazine. Lisa is a member of the Tulsa Chamber of Commerce as we all as the National Association of Women Business Owners. In addition to her work with OakTree, Lisa works with and supports many local and national charities including Muscular Dystrophy Association, American Cancer Society, Oklahoma Mozart, Meals On Wheels and others.
