Satisfied Clients
Rosemann is always a great partner on our development teams. Not only do they understand the complicated design process but also balancing the trade-offs between form and function. We know that we can count on them to work with the team to be within budget while providing a timely, high quality product.
– Joel Oliver, HALO Real Estate Ventures
I first partnered with Rosemann nearly 20 years ago and have found them to be creative and resourceful. They are particularly adept in the design, and administration and all around development of affordable housing resources. More importantly, as a firm they have the temperament and organizational capacity to deal with all the challenges that come with affordable housing development.
– Mark Stoker, RISE Community Development
We choose Rosemann because of their collaborative, no ego approach to our projects. We can rely on their honest and open communication, and our development teams come to each new community with confidence in Rosemann’s delivery of quality design. Our 12 projects completed together to date is a testament to our respect for their work.
