 Gladys Sera, PhD, PMP, PE | Managing Director & Your New Engineering Bestie

 For Gladys Sera, civil engineering is more than just calculations and concrete—it’s a vehicle for global change. As a first-generation Haitian immigrant raised in Florida, Gladys founded Sera Engineered, LLC in 2019 after seeing a vital need for better water resource management and stormwater infrastructure.  

Today, she brings that same heart and hustle to critical infrastructure projects across Florida (Palm Beach County) and the DMV (DC, Maryland, and Virginia).
What does an “Engineering Bestie” actually do?
Combining a Ph.D. in Sustainability with elite PE (Professional Engineer) and PMP credentials, Gladys makes the “scary” parts of land development easy. She specializes in:
  • Stormwater Management Systems: Making sure your site handles rain like a pro.
  • Utility Infrastructure Design: Solving the puzzles of wet and dry utilities.
  • Sustainability Consulting: Bringing PhD-level insight to eco-friendly land development.
  • Regulatory Navigation: Handling the complex permits of the East Coast so you don’t have to.
Whether she’s leading subject matter presentations or performing rigorous QA/QC for large-scale developments, Gladys is dedicated to delivering the design excellence that moves projects from “blueprint” to “built.”
If you’re looking for a civil engineering firm that values technical precision as much as a great working relationship, you’ve found it.
