HISTORY

"It Starts With A Vision" remains more than just a motto to HDA, it is how the company truly began and has continued to grow. In 1986, Jack Holleran (President) and Mark Duitsman (Retired) envisioned a Professional Service Firm providing exceptional design and customer service. Through their journey, the HDA staff has designed over 100 million square feet of projects in 44 states at a construction value of over $3 billion.
