Amadeus is a boutique MEP engineering studio founded in Los Angeles with a singular focus: people, precision, and purpose. We build differently — through communication, collaboration, and craft.

Agile. Creative. Focused. Collaborative. These aren’t just values — they’re how we work. At Amadeus, we design mechanical, electrical, and plumbing solutions that meet real-world needs. Our boutique scale is our strength: deliberate, hands-on, and deeply collaborative.

We don’t believe in business as usual. We believe in better — better design, better partnerships, better outcomes, better communication, better coordination, better follow-through. Amadeus exists to restore trust between engineers and architects — no ego, no noise, just systems in rhythm with design.

Engineering isn’t just what we do. It’s how we do it — with intention, with integrity, and with humanity at the core.

Isaiah Inderrieden, CEO of Amadeus, boutique Los Angeles MEP engineering firm.

Serving as the Chief Executive Officer and Director of Business Development at Amadeus, Isaiah leads the firm’s vision, client strategy, and organizational growth. With a background in design culture, organizational leadership, and the built environment, Isaiah brings a strategic, client-centered perspective to complex project development and long-term partnerships.

As the founder of Amadeus, he is responsible for cultivating strategic alliances, shaping the firm’s brand identity, and aligning its mission with a people-first, ethical practice. Isaiah works closely with the firm’s licensed Professional Engineers to ensure that every project reflects Amadeus’s commitment to quality, communication, and collaboration.

His career has evolved from hands-on experience in the built environment to executive leadership focused on firm development, operations, and client engagement. His path has been shaped not by credentials alone, but by a track record of resilience, creative problem-solving, and a belief that engineering firms can — and should — be built on integrity, equity, and lasting value.

While Isaiah oversees firm operations and client strategy, all technical work is performed under the responsible charge of licensed Professional Engineers in full compliance with California state regulations.
