Our differentiators

Nationally present, locally committed.

SEI is a network of locally owned and managed consulting firms, each supported by a team carefully chosen to guide, shape, and grow our offices and our clients’ businesses.

Fully accountable and fully invested.

Ownership is more than a financial
benefit, it’s a business mentality. We’re employee owned, which means every employee is invited to share in the benefits of ownership.

Meet a team. Sign an organization.

Each and every one of our team members is closely connected to the national organization, granting them access to diverse expertise and unmatched experience — because we work smarter together.

Experience comes standard.

Best of all, our team has years of directly applicable experience working in your industry — not just years of experience working across management consultancies.

Nationally networked, locally grown.

Explore the pivotal moments that have shaped our growth and reinforced our dedication to leading the industry.
