Founded in 2003, Milestone is an established leader in project management and project controls services in the Engineering Procurement Construction (EPC) megaproject environment. This work includes experience in compliance, risk management, and drafting and executing procedures for clients such as ExxonMobil, Fluor, Raytheon, British Petroleum, and international government agencies.

In 2017, Milestone expanded its focus to public agencies in Washington. Since then, we have secured project management, construction management, and project controls work with Sound Transit, the Port of Seattle, and the City of North Bend, as both a prime consultant and as a subconsultant in support of other local professional services firms.

Working as a strategic partner with our clients, Milestone ensures that our team brings value added services with integrity, dedication, and professionalism to each of our key stakeholders - every time.

Client Testimonials:

In the dynamic environment of project controls and processes, Amanda liaised with the key stakeholders, listened to their concerns, and then in turn successfully managed the processes necessary to reach outcomes that were accepted by all parties. She and her team put in place documentation controls, procedures, and execution plans that allowed us to continue operations and mitigate risk....There were schedule and cost benefits for our project as a result of these actions.

- Procurement Manager / Major Oil & Gas Company

I cannot emphasize enough how Sprang’s [Shesterkin's] work saved the PNG LNG Project tens of millions of dollars. Without her team, her ability to work with all involved, her ability to see the big picture and understand compliance, controls and administrative issues, we would not have been able to resolve our issues with ExxonMobil so positively. Amanda and the team she managed worked diligently and tirelessly to ensure the outcome was favorable for all involved.

- Customs Commissioner / Papua New Guinea Customs Service
