Business Relationships


Often in today’s fast-paced business environment, trust and integrity are in short supply.  These qualities, however, are essential in the relationships we build among equity partners, lenders and clients.  Properly founded relationships are crucial to developing successful projects.  Kelmore prides itself on establishing and nurturing relationships between these groups – relationships that will stand the test of time and attendant changes in the financial marketplace.  We have worked hard to establish credibility in the marketplace, and this shows in our relationships with lenders, be they insurance companies, pension funds, commercial banks or individual investors. 

Community Service


A fully integrated development organization recognizes that its impact extends beyond mere land and buildings.  Mr. Siecke has taken an active role in providing regional traffic improvements to the southeast corridor as a board member of area metropolitan district and as acting chairman of the Joint Southeast Public Improvements Association, a consortium of eleven metro districts.  Mr. Siecke and Mr. Koontz are also involved in numerous community organizations.  It is Kelmore’s firm belief that the community must be enriched by our projects.
