The Client

Dr. Will Bulsiewicz is a board-certified gastroenterologist and New York Times bestselling author — one of the most credible and accessible voices in gut health and plant-based nutrition. Through his work, his books, and his platform The Plant Fed Gut, he has built a global following of people who trust him to translate complex digestive science into guidance they can actually use.

His mission has always been to empower people with actionable knowledge about gut health. A course was the natural next step — a structured program that could take his evidence-based methodology and deliver it to a global audience in a format that went deeper than a book and broader than his clinical practice. He came to COURSE to build it.

The Challenge

Dr. Bulsiewicz's situation was similar to Dr. Uma Naidoo's in one important respect: he was a medical professional with an established audience and a bestselling book behind him, building a course that had to live up to both. The credibility was there. The audience was ready. The challenge was execution across four dimensions simultaneously.

The curriculum had to be evidence-based and scientifically rigorous without losing the accessibility that made his work resonate with people who didn't have medical backgrounds. Professional multimedia production had to match the quality standard his brand had established. The platform had to deliver a seamless, intuitive learning experience for a global student body. And the marketing strategy had to convert his existing audience and reach new ones — generating enrollment and revenue at a scale that reflected the genuine demand for what he was teaching.

What We Built Together

COURSE partnered with Dr. Bulsiewicz across course development, multimedia production, instructional design, platform integration, and marketing — building the full course ecosystem from strategy through launch.

Course development built the curriculum around the intersection of gut health science and plant-based nutrition that Dr. Bulsiewicz had spent his career researching and communicating. Scientific insights were organized alongside practical tools and actionable strategies — giving students both the understanding of why the science mattered and the specific steps to apply it to their own diets and habits. The curriculum was structured to be comprehensive without being overwhelming, moving students progressively through the material in a sequence that built knowledge and confidence together.

Professional video production and graphic design gave the course its visual quality. Dr. Bulsiewicz's teachings were transformed into engaging, professionally produced content that aligned with his brand and enhanced the learning experience — production that signaled to students that what they were about to learn had been built with the same care he brought to everything else under his name.

Instructional design added the interactive layer. Quizzes, case studies, and downloadable resources were built throughout to boost engagement and improve retention — giving students active participation in the learning process rather than passive consumption of content.

Platform integration gave the course a seamless home. Progress tracking, discussion boards, and easy resource access were configured to support a global student body moving through the program at their own pace, in their own time zones, on their own devices.

The marketing strategy was built to convert across multiple channels simultaneously. Persuasive sales copy, optimized landing pages, email campaigns, and social media content were developed alongside influencer collaborations and strategic partnerships that extended Dr. Bulsiewicz's reach beyond his existing audience and into new communities of people actively seeking guidance on gut health.

The Results

The course generated over $290,000 in revenue within six months of launch — attracting more than 8,000 students from around the world.

Learner feedback was consistently strong, praising the multimedia-rich lessons, the accessibility of the science, and the practical applicability of the strategies Dr. Bulsiewicz taught. The marketing effort meaningfully expanded his reach, bringing his gut health methodology to audiences who had found him through the course rather than through his books or social presence.

For a physician whose mission is to empower people with actionable knowledge about their health, 8,000 students in six months is a meaningful number — each one someone who might not have had access to that guidance without the course making it available.

What's Possible

Dr. Bulsiewicz had the medical credentials, the bestselling book, and a global audience primed to go deeper. COURSE built the curriculum, production, platform, and marketing that turned all of it into $290K+ in six months and 8,000 enrolled students.

If you're a clinician, researcher, or health expert with evidence-based knowledge and an audience ready to learn from you — this is what a properly built course launch looks like at scale.
