Apex Consulting Services Group (Apex) was founded in August of 2007 on three guiding principles:

∙ To provide Big-Four-level professional staff and services at Small Business labor rates
∙ To limit service offerings to only those areas where we clearly surpass the competition in service quality
∙ To establish long-term relationships with clients, built on a foundation of high quality services

The above principles can only be met if we consistently exceed client expectations.  We meet this challenge, in all our engagements, through demonstrated performance.


The Apex leadership team consists of seasoned professionals with extensive experience in the provision of our core service offerings to DoD and civilian federal government agencies. A synopsis of the background of our leadership team members is presented below.
