Our firm originally began as Milligan & Waltman, CPAs in 1983 when Danford D. Milligan, CPA and Douglas A. Waltman, CPA joined. It has changed several times over the years, bringing in new partners and using those opportunities to learn and become better as a firm. Doug Waltman was a founding member of the firm in 1983 bringing 8 years of experience in public accounting. R. Dean Hill joined the firm as a partner in 1994 bringing 17 years of experience in public accounting. Dean was in business with his father, Robert G. Hill, of the firm Hill & Hill CPAs.
