Chris Saxon


Chris has over sixteen years’ experience capturing Oklahoma state economic incentives dollars and federal tax credits for clients in multiple industries.  Only a handful of people in Oklahoma have been involved in as many Oklahoma Quality Jobs contracts as Chris has. 

Chris works directly with clients to quickly access eligibility and estimate benefits available.  In addition, Chris works with prospective clients to raise awareness of the programs available to new and existing businesses.  Through this process many learn, for the first time, that programs to help lower the cost of doing business exist.  Other companies that are aware of the programs may simply be reminded and updated on new or changing rules and regulations that may make the program more useful today or in the future.  Once we determine that a client should be eligible for the program, Chris and the SALTA team will guide them through the process of application and continuing compliance to maximize the bottom line result. For other clients who are in the program, but finding it difficult to timely file claims for rebates, SALTA will perform those compliance duties for a reasonable cost, providing assurance the filings are filed timely and all of the benefits that the client is entitled to are received.

A family man, Chris has three children and 4 grandchildren.  When he isn’t entertaining or playing with grandkids, Chris is an avid outdoorsman enjoying fishing and hunting whatever is in season.
