Third Party Underwriting is based in Naperville, Illinois.  We identify and form strategic partnerships with Program Administrators that have developed expertise and can demonstrate a quantifiable track record of generating underwriting profits.  We have both admitted and non-admitted capabilities licensed nationwide. Our philosophy is to respond quickly with our knowledgeable team and to limit channel conflict.
