We’re excited to announce our newest principals: Nicholas Martignetti, P.E., S.E., and Shaun Kreidel, P.E., S.E.!
These promotions recognize more than 15 years of sustained contributions from both Nick and Shaun—across project delivery, office leadership, client development, and the continued expansion of M+K’s national presence. Together, they have played key roles in shaping two of our most important growth markets on the West Coast and in the Southeast, helping establish and strengthen offices in San Diego and Atlanta. Their leadership reflects M+K’s practice: technical excellence, practical and buildable design solutions, and a commitment to long-term client relationships.
As Principals, Nick and Shaun will continue to lead their respective offices while also helping guide firmwide strategy, business development, and the development of the next generation of leadership. Their promotions mark both a recognition of what they’ve already built and a continued investment in the future growth and direction of M+K.
“Both Nick and Shaun bring capabilities that empower teams to achieve seamless, client-centric project delivery through refined and repeatable processes. By bridging the gap between executive leadership and day-on-day operations, they ensure that the firm’s strategic vision is directly translated through the teams and into high-quality work product. This renewed connection strengthens our corporate culture, ensuring that our leadership group remains deeply integrated with the technical excellence and efficiency of how we get work done.” – Jamie Friling, COO
Please join us in congratulating both Nick and Shaun on this well-earned achievement. Read more about each of them below.
Nicholas Martignetti, P.E., S.E.
Nick joined M+K in 2011 as a Staff Engineer and has steadily progressed through the organization, taking on roles as Project Engineer, Project Manager, Shareholder, and San Diego Office Director. Throughout his career, he has helped shape practical engineering solutions on complex projects, while building strong, trusted relationships with clients and colleagues alike.
Nick has been instrumental in shaping M+K’s San Diego office, driving the firm’s growth and visibility across the West. His leadership has advanced projects ranging from residential renovations and custom homes to large‑scale production builder work, opening doors to broader opportunities along the West Coast.
Across his work, Nick reflects M+K’s core strengths: technical expertise in wood-framed construction, responsiveness, and the ability to deliver clear, buildable, and efficient design solutions. He is also a strong advocate for early collaboration and value engineering to help clients achieve practical, cost-effective outcomes.
Nick’s approach to business development is rooted in relationships and consistency—leveraging direct outreach, referrals, and in-person engagement to build trust and long-term partnerships. Once engaged, he is known for maintaining momentum through responsive communication and timely delivery.
In his expanded role as Principal, Nick will continue to support the growth of M+K’s West Coast practice while contributing to the firm’s broader strategic direction and client development efforts.
Shaun Kreidel, P.E., S.E.
Shaun joined M+K in 2011 as a Staff Engineer and has grown into a trusted leader across the firm, advancing through roles including Project Engineer, Shareholder, and Atlanta Office Director. Over his tenure, he has played a key role in strengthening technical excellence, building lasting client relationships, and developing teams across the organization.
In 2017, Shaun took a leap, moving from Philadelphia to help strengthen M+K’s first satellite office in Atlanta. Today, the Atlanta office stands as a key part of our firm’s growth, with strong client relationships, an expanding team, and a growing presence across the Southeast. Shaun has helped establish M+K as a trusted partner in the market, bringing a deep understanding of both the technical and practical aspects of structural engineering, particularly in multifamily and wood framing projects where efficient, buildable solutions are essential.
As he steps into the role of Principal, Shaun will continue to lead the Atlanta office while helping guide the firm’s strategic direction. Looking ahead to 2026, he will play a key role in strengthening our business development effort, focusing on deepening existing relationships, expanding our network, and reinforcing M+K’s presence in the market.
Shaun is also focused on clearly communicating what sets M+K apart: our expertise in the “art” of wood framing, our ability to deliver practical, real-world solutions, and our continued investment in technology, research, and innovation.
Internally, Shaun is focused on supporting the next generation of leadership within the Atlanta office, ensuring continued strength in both client service and team development as the office evolves.
