Thank you Mr. Allen Caster for your assuring manner in which you extended to me during the fixing of my income tax with the Internal Revenue Service.  I had multiple years of outstanding taxes and limited documents to assist you in the effort.  Your knowledge in dealing with the IRS and Maryland provided you with the necessary information to complete my taxes and solve my delinquencies.  I now rest better at nights knowing that this matter is no longer haunting me and hampering my ability to move on in my financial growth.  Mr. Caster you are simply the best tax business I have ever worked with.

Exceptional Service!  Mr. Caster was referred to us by our former tax advisor.  His depth of knowledge and experience helped us with our troubling tax matters and estate challenges.  Mr. Caster provided expert guidance, support, and a ‘can do’ attitude that helped our family with our complex IRS matters and the Probate of our Uncle’s Estate in the DC Superior Court – Probate Division.  We are eternally grateful to him for his professionalism and compassion.
