Three Case Studies

New-Market Growth

Accelerated New-Market Growth 4x

Delta Gamma · 280K-member international organization

Delta Gamma's new-market expansion program had slowed considerably. The positioning, pitch materials, and acquisition approach no longer reflected how buyers evaluated the organization or what younger audiences responded to.

I rebuilt the positioning, updated the market-facing narrative, introduced localized acquisition strategies, and redesigned the supporting launch systems.

Earlier Revenue Turnaround

Revived a Stalled Revenue Product

American College of Radiology · 32K+ member professional association

The American College of Radiology's career-services product had stalled. Its pricing, positioning, and offer no longer matched the market. I developed a new business plan, evaluated competitors and vendors, rebuilt the positioning and pricing strategy, and led the relaunch.

Mini Case Studies

Marketing

Unclear Positioning

Leak

A creator had built a 14K-person audience but generated only about $1K in sales.

Fix

Narrowed the category, clarified the product line, and rebuilt the positioning and messaging.

Result

$20K in the first 30 days and seven figures within 18 months.

Sales

Conversion

Leak

A launch forecast at roughly 50 sales produced only four.

Fix

Diagnosed the messaging and conversion gap, then rebuilt the narrative and path to purchase.

Result

A later launch generated 67 sales.

Customer Success

Retention and Expansion

Leak

The business began with a single-service model, limiting how well it could retain customers and grow revenue from successful relationships.

Fix

Built a $7–$25K offer portfolio and lifecycle system with renewals, extensions, and clear paths into the next right level of support.

Result

Multiple customers remained engaged for two to four years, and the highest customer lifetime value exceeded $200K.

Operations

Founder-Dependent Execution

Leak

Content performance depended heavily on the founder and was not transferring successfully to the team.

Fix

Took over execution to identify what worked, then built the guidelines, templates, and operating process for handoff.

Result

Reach increased 22% and link clicks increased 117% after execution moved to the team.

Work Samples

AI & Automation Work Samples

Selected tools built with AI, automation, and lightweight technology.

Portfolio ICP Diagnostic

A reusable AI workflow that compares a company's stated ICP with the customer profile revealed in its actual client book. Gathers and enriches customer data, quantifies the strongest divergences, and produces a one-page, evidence-based brief for the leadership conversation.

Sample workflow output; company name redacted.

AI Campaign Builder

A reusable AI workflow that turns positioning, brand voice, customer insight, and launch strategy into coordinated first drafts across every required campaign channel. Compiles the strategic context once, generates aligned creative across email, social, web, and supporting assets, and gives a team a fully-aligned first pass to refine instead of blank pages.

Sample engine output; company name redacted.
