After more than 25 years in construction management and eight years with On Center Software, President Cecilia Padilla has announced her retirement, effective October 28, 2016. During her time as Vice President and President, Padilla has reinvigorated On Center’s focus on construction software that increases efficiency, accuracy, teamwork and ease of use for the spectrum of construction trades. She served on the company’s executive Vision Team, a think tank on the future of construction automation. She introduced the industry’s first cloud-based platform – Oasis Takeoff® and Oasis FieldCenter®.
Padilla has been in construction her entire life, following her father into contracting. She began her career with the Raymond Group, in Orange, California as their first female junior estimator. She became a senior project manager and area manager, in California and Nevada with several multi-million-dollar projects over 12 years. Padilla and her husband moved to Houston and she joined Marek Brothers Systems as a senior project manager, where she was introduced to On Center’s Quick Bid® and On-Screen Takeoff®.
“Working with On-Screen Takeoff and Quick Bid together was amazing. I felt that I could make the software tap dance for me. I had the opportunity to try out beta versions of software years before joining the company. I became one of On Center’s greatest fans; I knew the power of software automation,” Padilla explained.
In 2008 Padilla was recruited to On Center as Vice President, selected by the company’s founder Leonard Buzz to become his successor after he retired in 2013.
“It has been an honor and privilege to work with all of you during the last eight years, I’ve seen your growth as individuals and as a team, and I am confident in the choice I made for my successor, Angelo Castelli.”
Angelo M. Castelli becomes On Center President on October 28, 2016. He joined On Center as Sales Manager in 2003 after 10 years as chief estimator and project manager with Western Reserve Interiors of Cleveland, Ohio. He rose through management roles at On Center to Chief Operations Officer most recently. Castelli was instrumental in the creation and deployment of business development and plan room programs. As a direct result, On Center Software is used in over 200 academic institutions as required curriculum for construction management degrees. As member of the Vision Team, he is a great proponent of a cloud-based software platform and the real-time collaboration it brings to construction.
“Coming from construction, Cecilia and I share the same passion for what On Center Software does for construction companies. It makes contractors’ jobs easier, and their companies more profitable,” Castelli said. “We are excited for her and look forward to hearing about her global travels during retirement.”
“Our focus has always been to take care of our customers. We receive tremendous satisfaction when contractors tell us how we have helped their businesses. It is at the core of On Center’s culture. You know that Angelo, and every On Center employee, carry that attitude,” Padilla added. “You are an amazing group, and I will miss working with you every day.”
