- Low staff morale
Our interim executive stepped in immediately, bringing financial expertise, implementing improved reporting systems, and mentoring existing staff. Within six months, the organization saw:
- Stronger financial controls

- Increased board confidence in fiscal oversight
The result? A seamless transition to a new permanent leader, with the organization positioned for long-term success.

Can we use ProNexus to supplement current c-suite roles or do specific project work?
YES! We know that leaders in c-suite roles often need some additional training and development. We can come along side that professional and help develop them specific to what the organization’s needs are. Whether it be helping them navigate the unique role they are that tasks them with reporting out to a board of directors and overseeing a variety of roles or improving compliance and stakeholder satisfaction, we can come along side them and equip them for long term success. We also do specific project work. Just get awarded a grant to start up a program? We can bring in a professional to do the start up, hire the permanent leader and team members and create the infrastructure for a successful program. Need a struggling program turned around quickly? We can quickly assess the program and work with the larger team to have that program turned around in timely fashion.
