Women-Owned Business Resources
One of the most desirable aspects of a landscape architecture career is the opportunity to have one’s own practice. This is especially attractive for women who want to maintain a flexible work schedule to balance their personal and professional lives. An added benefit to women entrepreneurs is the fact that many municipalities and agencies give preference to women and minority owned businesses. There are many organizations and resources available for women-owned businesses and we urge our members to seek out all the resources and benefits to owning a landscape architecture practice. Below are a handful of resources to get you started:

Small Business Administration
Women-Owned Business Certification
Women’s Business Enterprise National Council
