Streamline Leadership

Mike Stillwell


Mike entered his career in 2000 being accepted into the Steamfitters local 420 apprentice program. After graduating from the 5-year program and working on many large-scale projects such as, Citizens Bank Park, Tower at Children’s Hospital, Merck pharmaceutical sites, he was considered a journeyman. Six months after graduating, Mike was promoted to foreman where he was now responsible to run projects under his direction. In 2007, at the age of 26, with an entrepreneur spirit and drive, Mike ventured toward Philadelphia neighborhoods to begin his passion for creating a thriving construction and development process in urban markets. Streamline was formed with a vision to simplify the construction process. While working in Point Breeze, he met his business partner who had a similar vision. Their instant bond, trust, and shared business goals quickly blossomed into a partnership in 2008 at the height of the recession. The partners saw a need & a service opportunity to enhance the process for the new construction consumer as well as streamline the construction process for development. Mike’s persistence and self-motivated drive to create a positive impact within Philadelphia quickly led to rapid growth for Streamline. At the start, funds were raised by friends & family. The team began walking the neighborhoods of Philadelphia to build relationships with community leaders and local residents, to source projects where they could rebuild and improve the neighborhood. Mike quickly developed and managed the construction team which he led to create processes and procedures for future rapid growth and expansion, to maintain the growth and strategy Sean was pursuing.Today, Mike is the CEO of Streamline, overseeing a leadership team that manages 65 employees within 5 divisions: Acquisitions, Investment Management, Development & Construction, Realty, and Warranty Services.
