My company has been working with Mia for more than 20 years. She has completed a multitude of projects for us from tenant improvements, including our company’s office relocations, lobby renovations, to full building conversions of older assets which we repurposed into Class A office buildings. Mia understands the design process and pulls together a complete team to make the project successful. She also understands how to bridge the gap between owners and contractors by creating a design and drawings that are constructable, and aligned with the owner’s vision and budget. Once designed and permitted she stays committed to each project to maintain design intent and the owner’s budget.

I have had the pleasure of working with Mia at virtually all points of her career. To suggest that Mia is dependable, would be an understatement. Mia has demonstrated the unique ability to provide great design that answers to all stake-holders. Understanding the balance between client and owner is a trait she has mastered. She is responsive, thoughtful and can be trusted to respect deadlines. I’d be delighted to see Mia on any project in any of our assets.
