Tom Sill

Associate Professor

  • M.B.A. Seattle Pacific University, 1990
  • B.A. Central Washington University, 1984


Tom Sill received a double Bachelors degree in Accounting and Finance from Central Washington University in 1984. He worked as a Cost Accountant for Boeing for 3 years and was then put in-charge of the Income Statement. He later became a Systems Analyst manager at Boeing and designed their replacement accounting system. During that time, he achieved his greatest scholastic goal of passing the CPA exam (which had a 6% passing rate), crediting prayer and God’'s grace for that victory.  He also completed an MBA (Cum Laude) from SPU, which was paid for by Boeing.

He then leveraged his degree and CPA exam scores to a new job, as an auditor for a CPA firm in Seattle.  He also did tax consulting for clients for over 10 years.

In 1990, he career-shifted from the practice of accounting to the teaching of accounting and taught at several Seattle-area community colleges for a total of 8 years.  In 1999, he advanced to an Assistant Professor position at NU, and served as the chair of the Business Department for four years.  During those years, he founded and managed the student-led Aeries Coffee Shop and designed/built a triplex, which he still lives in. He became a tenured professor in 2009.

In addition to teaching, he currently consults for a very successful specialized auditing firm in Bellevue performing post audit review.  In the past 2 years, he has personally saved his client over $1,000,000.

Aside from teaching, Tom co-leads a very active street evangelism team called InsideOUT ministries (“taking what is Inside the church OUT to the world”) and serves with his wife Gretchen in a vibrant international student ministry.  He manages his triplex located on the shores of Lake Desire.  His life goal is to live a life pleasing to God, thereby giving God a smile (Eph.4:1).
