SLL develops innovative building solutions for organizations, businesses, building owners and developers. Together, we build amazing projects.


Empowering A Team

If you ask people at SLL what keeps us excited about coming to work each day, you’ll hear repeatedly that it’s the people. We revel in the opportunity to work with such diverse people from so many fields of construction. Our team is open, collaborative and fun – all reflected in our passion exuding into each project.

S.L.Leonard & Associates brings an important element to the table: Because they focus on the details of building, negotiating and bidding, we are freed up to focus on accomplishing our vision. And because they have worked every job around the table at most construction meetings, they bring credibility in working with the contractors. Their requests are always grounded in experience, which makes the process much more productive. Sean and Mike make a nice team—Sean has a quiet authority and Mike is always prepared to push hard to represent the client. Together, they maintain the positive relationships necessary to keep the project moving along with the client’s interests well represented.

S.L. Leonard & Associates is a true partner with us. Jamboree Housing just had its biggest year, closing eight deals representing about $200 million in construction, and we could not have done it without S.L. Leonard & Associates. We have a diverse product line, including rehab, slab on grade and podiums, and S.L. Leonard & Associates handles it all well. Their team is versatile and brings a deep level of technical expertise to the table, along with sharp negotiation skills. They work in lock-step with our project managers to ensure our high quality standard while keeping up with a pipeline of fast-moving projects.

Our People

Paying It Forward

We have a long and deep tradition of volunteer leadership and financial support for the non-profit agencies that make our communities better places for all people. We contribute thousands of hours of volunteer service in our communities each year, and our firm acts as a conduit to help people get connected to the service opportunities that mean the most to them.

A Proven Process

Step 1.

Understand The Vision

Every project starts with a discovery and strategy phase. Our team begins to understand the insights, budget and goals for the project. The outcome of this phase is an understanding of strategy and requirements moving forward.

Step 2.

Build The Team

Once the game plan has been established in the vision phase, the project moves into the team phase. This part can be meticulous and incredibly detailed; but it matters, A LOT! The project’s architects, general contractors and engineers are all selected.

Step 3.

Project Planning

The project planning phase is the blueprint phase of the project. Feasibility studies, permitting, environmental reviews, value engineering and FF&E discussions are all part of the project planning phase.

Step 4.

Project Execution

The project execution phase is where you get to see your project come to life. A weekly construction meeting, managing lenders, public outreach, internal board communication and reviewing pay requests are all integral steps of the project execution phase.

Step 5.

Project Close-Out

Finally! The project is almost complete and ready for occupancy. Recording drawings, creating operations/maintenance manuals, executing final lien waivers and an 11 month walk through are the final steps in wrapping up your project!

This business was built on a strong foundation of quality, integrity, and experience. We are a collective team driven by passion and united by purpose.

My nonprofit business, the L.A. Kitchen, was looking for the right company to help rep us as we built out a new kitchen/social enterprise in Los Angeles. This was the first kitchen I’ve built from scratch, so I needed a real pro…but more importantly, a pro who didn’t see us as just another client. I was looking for a person who shared my sense of purpose, who really cared about “why” I was building it. I found that person in Sean Leonard. He’s a pro’s pro…but more than that, he’s a great guy. He and his team are rock solid. Timely, knowledgable, professional and great people to do business with. We can’t say enough good things about them.
Robert Egger, Founder & CEO, L.A. Kitchen
Working with S.L. Leonard & Associates has been a true delight. Sean Leonard is a consummate professional, a skilled diplomat, and is extraordinarily competent in the field of project management. A review of his resume will validate these superlative comments. My endorsement of his work is without reservation. If I need a project manager in the future, S.L. Leonard & Associates will be my first, second and third choices.
