Who we are

In addition to being a company, OakTree is also a family. Since 1999, 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 sensations for us than calling an applicant to say "you've got the job," 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.

Kamron Cox

Senior Technical Recruiter

As a seasoned IT Recruiter with over 10 years in the IT Staffing industry I've helped hundreds of IT people find the right career path. I specialize in finding talented professionals in the IT field and matching them with their career goals and new opportunities. My Focus has been on Permanent positions and Contract opportunities in the IT Field. 


With the war on Talent in IT getting slimmer, it's good to know you can trust someone to get you on the right career path. There are 4 main things I will cover with you in order to make your next career move a success. Check out my 4 point system.

1. Determine your Career Goals and Vision: Goals are the steps that will move you closer to making your overall vision a reality. Accordingly, each goal, whether short-term or long-term, needs to align with your vision. Your vision reflects what you truly want to achieve in life.

2. Career Assessment: A personal assessment selected by individuals vary depending on their personal beliefs regarding the most important criteria when considering career choices, as well as the unique needs of the individual considering a career decision.

3. Resume Critique: Writing a great resume does not necessarily mean you should follow the rules you hear through the grapevine. It does not have to be one page or follow a specific resume format. Every resume is a one-of-a-kind marketing communication. It should be appropriate to your situation and position you’re trying to obtain.

4. Interview Preparation: The biggest mistake in interviewing is not being fully prepared. It behooves job-seekers to use every conceivable means possible to prepare for the interview and to allow ample time to fully prepare. Understand that interviewing is a skill; as with all skills, preparation and practice enhance the quality of that skill.
