Lisle Township Assessor

Vote for 1By law, Illinois Townships are charged with three basic functions:1. General Assistance for those in need;2. The assessment of real property for the basis of local taxation;3. Maintenance of all roads and bridges outside federal, state and other local jurisdictions.The Township Assessor is required by law to uniformly assess properties at a median level of 33 1/3% (one third) of market value. Equitable assessments ensure a fair distribution of the property tax burden among all property owners. Local property taxes pay for such services as schools, villages, libraries, park districts, and fire protection districts.The Assessor's staff maintains a file for every property located within the township. This file includes the lot size, building sketch if the property is improved, and descriptions of the improvements. When buildings are constructed, the assessor's staff gathers information from field inspections of each property. Changes to properties are monitored through building permits, sales listing information, and neighborhood inspections.More information: Lisle Township

My education includes a B.A. in Marketing from North Central College. I have over 600 hours of post graduate real estate specialized coursework. I have over 38 years in the real estate valuation business and have completed valuation assignments of commercial and industrial properties in 48 states and Canada. I have been involved in special projects including converting Wisconsin’s Gross Receipts Tax to real and personal property for Wisconsin Bell. Other projects include petroleum and chemical refineries as well as nuclear power plants. I have been your Assessor for the last 27 years.
In my opinion the Department of Revenue needs to update their factoring practices and methodologies. In a bifurcated market and the resulting market compression, the Department of Revenue needs to permit sector-based data in developing factors. This would permit the Assessor the ability to refine factors within the Township resulting in greater accuracy within specific market sectors.
When I took office, we had 16 employees and 36,500 parcels. Since taking office, we have been burdened with many unfunded mandates from Springfield. Currently we maintain 42,000 parcels with five full time employees and three part time employees.

I am fortunate to have very dedicated individuals working in the office. Three of the individuals have been with me for over 25 years. We are constantly looking for ways to cut costs and improve services. I would prefer not to speculate on any one project as we are focused on results and not gimmicky promises.
I believe Lisle Township currently provides quite a bit of transparency. Publishing our checkbook online supports that claim. Publishing our agendas, minutes as well as archiving the same provides the taxpayer all the information they need. Auditing our expenditures by rotating trustees and having every bill available as a part of our monthly meetings is, in my opinion, the ultimate in transparency. Additionally, the Highway Commissioner and Assessor attend the meetings as a courtesy on the chance any question arises on a bill submission.
