With a commitment to empowering professionals, ISTI continues to shape the future of sex and relationship therapy through innovation, expertise, and a dedication to improving client outcomes.
The
Issues
When ISTI approached us, their 10-year-old website was outdated and non-functional, failing to represent their prestigious certification programs. They relied heavily on third-party tools and email chains to manage student curriculums, online coursework, and live Zoom sessions, creating a chaotic and inefficient system. Despite being a highly sought-after certification program with global recognition, ISTI lacked a professional and cohesive online presence to match their reputation and support their growing student base effectively. This disorganized structure was holding back their potential to scale and deliver the seamless experience their students deserved.

Working with the Integrative Sex Therapy Institute (ISTI) on this massive project was one of our largest and most rewarding undertakings to date!

The
Impact
HG Design+ transformed ISTI into a modern, cutting-edge institution, elevating their online presence and operational capabilities to new heights. We developed an integrated, college-level e-learning system featuring multiple course tracks, certification fulfillment, credit tracking, and a fully custom-built platform for pre-recorded and live courses. Students can now seamlessly enroll, sign up, and attend live classes, all from a beautifully designed and highly functional website.
This was one of our most ambitious projects, redefining education management technology with a robust system tailored for professors, administrators, and students alike. The results have been extraordinary: ISTI has seen a 50% increase in enrollment, higher attendance rates for online courses, and glowing feedback from students who can now focus on their education without the frustrations of outdated systems. This success is a testament to how innovation and thoughtful design can unlock incredible potential, and we couldn’t be prouder to support ISTI in their mission to educate and inspire the next generation of therapists!
