Tiller Consulting Group, Inc. is an independent consulting firm specializing in actuarial and enterprise risk management consulting services. Founded in 1984 by principals with many years of consulting experience, Tiller Consulting Group, Inc. provides added value above the ordinary to its clients.

We consult in the property and casualty insurance lines and in group health. Our clients include individual entities retaining risks, workers' compensation and other risk sharing pools, insurance companies, insurance departments, and law firms. We have clients in both the public and private sectors.

We take pride in treating each project on its own merits, with no preconceived notions of the results. We use each client's data to the extent possible. We are compensated by and have direct responsibility only to the client for whom work is performed and to any governmental oversight body on behalf of the public. No assignments are undertaken that would impair the firm's independence or objectivity.

We work directly with operational decision makers and Boards of Directors on all aspects of the organization to solve short- and long-term problems and help assure long-term profitability. We are well known for our ability to communicate complicated concepts in layman's language and believe the best decisions are made when the client understands the situation and the consequences of decisions. We also believe that it is in our clients' best long term interests for us to tell them what we think, whether it is what they want to hear or not.

We would love to talk with you about your entity's needs. Please contact us for additional information.
