Livonia, MI, United States


In 1962, OHM Advisors (Orchard Hiltz & McCliment, Inc.) began with a simple premise: to create extraordinary relationships with our clients. John E. Hiltz joined forces with Melvin (Ernie) Orchard to form John E. Hiltz & Associates, starting with 15 employees. In 2012, we celebrated 50 years of Advancing Communities. Along the way we've delivered solutions, service and insights that provide value to our clients – many of whom have been with us since day one. In recent years, we’ve continued to stretch ourselves; expanding our capabilities and our footprint by joining forces with architecture and engineering firm Hitch, Inc. in 2005 and opening several regional offices. In 2010, our merger with Ohio-based Bird Houk Collaborative joined their private sector market savvy with our public sector expertise. Since 2011, we 've opened offices in Mount Pleasant and Saginaw, Michigan.



OHM Advisors is an integrated engineering, architecture and planning firm committed to advancing communities. We devote our public and private sector expertise, forward thinking and insightful counsel to enhancing the built environment and the natural world. At OHM Advisors, we believe in holistic thinking and services tailored to meet our clients' ambitions.
