About SAI Print E-mail

SAI Valuations, LLC is a Valuation Applications company, which has its corporate headquarters in Las Vegas, Nevada, with offices in Chicago, Illinois, and Portsmouth, New Hampshire.  SAI is a multi-discipline company that offers a wide range of appraisal and valuation services, both nationally and worldwide.

Corporate History

SAI Valuations, LLC has evolved from several entities. The company got its start as J & B Aviation, which was formed in 1991 by John and Barbara Spoor as a FAA maintenance facility.  In addition to the maintenance facility, the company maintained and restored antique/classic aircraft and provided instruction. 

J&B Aviation became Specialty Aviation, Inc. in December of 2002 in response to additional opportunities in the aviation industry.  Specialty Aviation, Inc. evolved into a premier aircraft and aviation valuation business.  It has been involved in thousands of aircraft appraisals from light single engine to heavy airline transport aircraft.  Specialty Aviation, Inc. specialized in aircraft valuation, aviation business & facilities valuation, asset risk management, technical consulting and legal expert witness.  In addition to onsite maintenance, the company’s maintenance facility developed into a “state of the art” technical research and inspection division that supports each valuation project.  

What set Specialty Aviation Inc. ahead of its competitors were the staff members.  Each consultant had experience specific to the aviation industry and had received extensive company training.  Each assignment was diligently pursued to arrive at the most accurate solution and/or conclusion as defined by the scope of the project.  The quality service provided to our clients is known for its responsiveness and innovative use of technology.  

On the 16th of February 2007, Specialty Aviation, Inc. acquired AMS Appraisals & Valuations and changed its name to SAI Valuations, LLC.  The acquisition of this prestigious New Hampshire firm provided an opportunity to become one of the largest aviation valuation firms in the world.
