I am pleased to introduce the team that works together to transform buildings and create lifelong clients.

Our Team


Founder/Senior Project Manager

Stephen Mardena has been working on construction sites since he was fourteen years old. Stephen began his career cleaning construction sites in New York City. He quickly progressed from simple janitorial duties to experimenting with tools, the first of which was a jigsaw used to cut a formica countertop for a kitchen sink. (old, right? lol) 

Stephen got a job as a Carpenter Apprentice and then became a Carpenter after working at various job sites over the summer. He worked his way up to the position of Jobsite Foreman, where he was in charge of his projects and labor crew. Stephen rose through the ranks after a few years to become a Superintendent, then a Project Manager.

Stephen’s construction resume grew over the years to include high-quality commercial and residential projects. His diverse construction experience fueled his desire to learn more. This desire eventually drove him to leave the family business and establish his own, which he owned and operated for over ten years. Stephen was thrilled at the prospect of being his own boss in his hometown but was also eager to gain new skills and experience. In 2018, he relocated to the west coast, beginning a new chapter in Los Angeles.

Working as the Vice President of Operations for a Downtown Los Angeles company specializing in high-end restaurants helped Stephen learn the ins and outs of the local construction industry. He was responsible for developing new clientele and enhancing the company’s standing in the hospitality sector. Stephen was able to network with some of the most well-known subcontractors, architects, and designers in Los Angeles’ downtown area and gain insight into the ins and outs of the design-build process.

Stephen’s local experience also includes working for one of the largest restoration firms in the country, where he gained a wealth of knowledge about the insurance industry and property damage and restoration processes. He quickly developed a passion for this sector and began training and schooling to provide this emergency service to his valued clients.

Stephen founded Mardena Construction because he recognized a market need for a company whose primary objective is to realize the client’s vision. Now that he has full company and creative control, he can provide clients with the construction experience they expect and value. 

In his spare time, Stephen enjoys spending time with his family, watching basketball, golfing, and volunteering in his community. He also enjoys watching cooking shows and experimenting with new recipes, though his skills do not yet rival those of Gordon Ramsey.
