Instructor Details

Jellis Vaes

Hey! I’m Jellis Vaes, a mental health coach currently studying to become a clinical psychologist. I’m also the founder of Inner Path Seekers, a space for mental health support, and The Heart Warrior Project, which is a support platform for cardiac arrest survivors.

Creativity is at my core, and I primarily work on my own projects as a content creator. I produce articles, videos, podcast episodes, events, and online courses, which you can explore here.

Some of the courses I offer are part of my project (Inner Path Seekers), but most have been developed as I’ve accumulated skills on various topics and wanted to share them with others eager to learn more.

When I’m not holding therapy or coaching sessions, or working on my projects, you’ll likely find me out in the mountains or traveling with a camera in hand. I’m an avid adventurer with a passion for alpinism.

In the past, I used to work as a travel and adventure photographer/videographer, which is why you’ll still find some courses on photography here as well.

I hope to welcome you to one of my courses soon!

Well explained and easy to folllow. Lots of quality information, presented in a professional manner and is interesting to listen. If I would have any advice, it would be to try to improve your english a little bit more, but I know that does take time. I was raised French and it took me quite a long time to improve my English. Also I would say if you could add more excitement from time to time it would increase the entertainment of your course. Maybe stand up from time to time to demonstrate something or write on a white board would help with that. All and all, very well done, highly recommend and appreciate your general vibe. I will actually gift this course to my brother shortly. Lots of love and appreciation for who you are and what you do.

By Lynn D. on 1/5/2024

So far so good. He seems very knowledgable and all the information so far has been very useful. I like the pace he is talking at and he is very clear. I am taking a lot of notes and each section is so good that I cannot wait to move onto the next one. I chose his course over others because he noticed that he updates it regularly, while other creators don't review their content at all.

By Peter Ilas on 12/8/2023

Jellis focuses on teaching how to create a course of high quality with added value content. I enjoyed simple yet powerful ways ideal for a novice like me. He advises on little but important things like improving the video and audio and provides links to videos by professionals in lighting, audio, and more. All his lessons are short and to the point. What impressed me most was the marketing section, where I expected paid ads. Instead, Jellis suggests strategies for creating a free of charge content and posting/distributing to the audience. This is one example where this course is not only for beginners but also to level up in the future. I want to create my first course in a style and level as Jellis did this one :)

By Ns on 9/15/2023

You did a great job covering all of the key aspects and tradeoffs when deciding on various options that come up. The student is able to navigate and focus on course content without getting derailed. I see your detailed Q/A responses even after 3 years including photos which shows your effort and engagement level even until today. Many instructors stop answering questions after a while. Kudos to you.

By Gustavo Gallego on 8/9/2023

El curso es super completo y aborda diferentes temáticas claves del end to end de la creación de cursos. Además te entrega herramientas para dar los primeros pasos en este apasionante mundo. Ya estoy esperando la segunda parte. Sería ideal poder encontrar a lo largo del curso otros ejemplos de creadores de cursos y contenidos para enriquecer la experiencia.

By Roxanne Bouwer on 6/20/2023

Really amazing course, very helpful, clear voice and audio and a friendly face. The detailed content and dedication to helping others create courses is very valuable. The teacher provides ideas, methods and tips for every step of the journey, things that I didn't even realise of think of. He makes it simple and easy to understand and implement yourself. Thank you so much!

By Stefan Breisch on 6/12/2023

Great course! It really helped me to get started on the course creation and made me aware of all the points I need to pay special attention to. Everything is explained clearly in a concise way without running of track and in an engaing way. Video and audio quality is top-notch. Thanks a lot Jellis

By Lisa Chaly on 1/29/2023

Although I was looking for a more in-depth course on how to actually write/create the course from scratch (as in the content, meat and bones of it), this course provided a great overview of the whole process of creating a course. I appreciated the length of the videos, the instructor’s enthusiasm, breadth of knowledge on the topic, and his tips and tricks for creating a best-selling course. He had wonderful insights to share and I had several “Aha” moments, which I will be able to implement into creating my own courses. I found his pace and demeanor pleasant, friendly, and easy to follow. After completing the whole course, I feel I am better equipped to create valuable courses that are engaging, inspiring, and very informative and feel excited to get started!! Thank you for a great course; glad I decided to enroll and dive right in!!

By Konrad Rutten on 8/10/2022

Ok, Finally finished! It was a marathon! The good, the bad, and the ugly! Ugly, what? Ugly is a variation of beauty. In this case, what you improve on? The good, your hard work, integrity, and positivity. Your content was good, and your delivery was good. The bad, not enough examples! The ugly, you were telling, and not showing. I'm an experiential sort of guy, and need to apply. To be honest with you, I listened to the last part of your class as a podcast. I hope you value my honesty! Konrad
