Executive Summary (TL;DR)
Leadership coach Grainger Marburg grew his consulting practice through SIAN by building trust in small-group settings, earning a warm, right-fit referral from a longtime member, and delivering a tailored training series that delighted the client.
Result: qualified business, stronger reputation, ongoing community support.
The Consultant
A former nonprofit CEO turned executive coach, Grainger brings lived experience with board dynamics, fundraising pressures, and team leadership — credibility that resonates with nonprofit clients and SIAN peers alike.
The SIAN Moment: From Relationship to Right-Fit Referral
Through ongoing participation in networking opportunities with Katharine Earhart (Fairlight Advisors), she got to know Grainger’s temperament and approach.
That familiarity mattered when Katharine referred him to a client: a newer executive director with board-boundary challenges and a developing team. Because Katharine knew Grainger’s style and background, the introduction felt warm and low-risk for the client.
Why this works: SIAN helps consultants show how they think and who they are, so referrers can vouch for both expertise and fit.
The Client Need
- Clarify board vs. staff boundaries for a long-tenured, opinionated board
- Provide leadership development for a relatively new team
- Find support the executive director would feel comfortable using and funding
The Solution: Short, Targeted Team Trainings
Rather than an overwhelming, all-day workshop, Grainger designed a multi-month series of short, focused trainings (with lunch), making each session an engaging, practical “event” that leveled skills across the team. The format increased attention, retention, and morale. The executive director was very happy with the outcome.
Outcomes for Grainger (the Consultant Benefits)
1) Qualified Revenue via Warm Referral
The engagement came directly through SIAN relationships — no cold outreach, no guesswork about fit. Consistent participation builds top-of-mind awareness.
2) Expanded Services & Credibility
By pairing coaching with team training, Grainger addressed leadership growth and organizational capacity. That strengthened his value proposition and reinforced Katharine’s trust in him. That trust is key: a respected member’s recommendation shortens sales cycles.
3) A Community That Reduces Isolation
Getting to know SIAN members in smaller group settings allows for idea testing, reality checks, and strategic troubleshooting — vital for solo consultants and mirroring the support nonprofit leaders often need. It also helps peers get to know your style, so introductions land better.
