What They Say

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.

Leonard and Associates was very responsive to our needs and added value on all three developments. Sean and his team assisted us with oversight of the entire construction process, from review of construction documents and assistance with the bidding process and selection of our general contractors through the construction process. S.L. Leonard and Associates became a critical member of our construction team and their services improved the quality of our developments overall.

What They Say

Sean and Mike are just terrific, and they offer a balanced perspective. We were having some bumpy spots with Olive Court and had gone through several construction project managers. I was beginning to think maybe we shouldn’t even hire one! But after seeing the work Sean and his team did on Fuller Lofts, we decided to bring him on board for this project, even though it was late in the game. Mike has been great as an interface between me and the contractor, allowing me to not be in the firing line.
Claire Bowin, Development Director, Livable Places
During the construction, we faced some major obstacles. However, in every case Mr. Leonard facilitated the resolution effectively and amiably to the satisfaction of all parties. My encounters with Mr. Leonard were always pleasant and met with the utmost professionalism. The building of this most unique hall was steered by a talented and devoted project management group. The successful completion and outstanding results were recognized and celebrated by many worldwide.

Leandro Tyberg, President/Co-Founder, Primestor Development, Inc.

I hired Sean to project manage the build out of a 20,000 sf office space. Sean and his team assisted with every aspect of this project from space planning, construction management through furniture installation. With the help of Sean’s team, we delivered a high-quality build-out on time and on budget. I highly recommend Sean and recently hired him for another project to assist with a smaller space planning initiative.
