  • Clozure Associates specializes in Common Lisp programming. We have a large team of Lisp experts available for nearly any project, including:

  • Creating custom applications to your specification.
  • Extending your team with part-time or full-time programmers.
  • Maintaining existing Lisp software: fixing bugs, improving performance, extending functionality.
  • Porting systems to new platforms and modern architectures.
  • Creating application-specific improvements to dynamic language compilers, garbage collectors, and open source libraries.


  • Clozure Associates developed and maintains Clozure Common Lisp, but we are equally comfortable working in other Common Lisp implementations, including SBCL, LispWorks, and Allegro CL.
