Are you ready to open a new portal?

We need you to be your most authentic self in the spiritual industry. Coaches, energy workers, facilitators, retreat hosts, yoga and meditation teachers. This is YOUR year.


Girl, I don't want you to struggle. You should be living your best abundant, free and joyous life.

Be honest, are you:

  • struggling with showing up as your most authentic self online and offline?

  • ready to step into your leader and teacher role, but have no idea how?

  • feeling the call to use astrology but find everything and everyone so overwhelming?

  • missing the community and support to make your business flourish? Where are all the like minded people who want to grow as much as you do?

  • having a hard time taking the time for your much needed self-care and me-time?

  • continuously working hard on your dreams BUT also on the verge of burning out?

That's not a way to live...

Mystical woman. Are you ready for expansion?

Astrology is becoming more and more popular and for good reasons. This higher knowledge is the tool to healing, deeper understanding, expansion and soul’s growth. In Cosmic Mastery you will learn how to use astrology the RIGHT way.

I found my soul’s purpose through astrology and with this came so much abundance, fulfilment and an amazing feeling of alignment. I am here to share everything I’ve learned with you.

I spent hours and hours with old astrology books, devouring podcast after podcast.  
But you don’t have to do all that.

So who am I?

My name is Josie and I’ve been working with astrology for 8 years now. It all started with my longing to understand myself and others on a deeper level. When I fell into this beautiful rabbit hole it brought me so much more than I anticipated. Astrology brings people together. It connects people, helps the healing process to self acceptance and stimulates empowerment. Everyone should know astrology.

There is so much to learn from the planets when you learn how to translate their teachings, and I would love to share this beautiful language with you.

Astrology changed my perspective, helped me break patterns and accept myself fully and completely. Outside of the inside succes, thanks to astrology I was also able to help hundreds of people, publish 3 books and continue a purposeful career, doing what I love the most.

I’ve created Cosmic Mastery because I struggled and failed in business so you don’t have to. In 2015 I started my own business and slowly created my personal brand. Now, in 2024 I launched successful programs, taught classes and grew a beautiful and loving community that gave me freedom and stability. Doing something you LOVE with purpose is so important.

I am here to hold your hand and share with you all that can help you to fully expand and share your own business in the most authentic and sustainable way.


Let's master the Cosmic wisdom inside and outside of ourselves

This is who you are

an ambitious woman with a deep longing to expand in all levels of her life

someone who wants to create more impact and knows deep down she is meant to do greater things, reach more people

Mystical, spiritual, driven, unique and creative with a strong message to share with the world and your community

wants to learn astrology and use it to help reach succes and deeply help your clients


you're overwhelmed by all your ideas and don't know where to start

you haven't unlocked your 'key' to succes and have a hard time cultivating your tone of voice, your message etc

you're stuck and have no idea how to attract your dream customers.

you've tried to begin with astrology but it's too much and too overwhelming.

Unleash your mystical side, it's time.

embrace it.

Nope. Anyone with any level of knowledge is welcome. Even if you only know about sun signs ;).

Cosmic Mastery is a program that guides you step by step within a timeframe of 5-6 months. Every new astrological season, new videos and tools will be released. This is so that we don’t get overwhelmed by all the information and can integrate what we’ve learned (let’s balance this yin and yang energy ;)).

I practice Western astrology and use the Placidus system. But feel free to use any house system that works for you. Don’t be afraid to explore ;).

Depending on your knowledge and experience it is definitely possible to become an astrologer after this program! Even if you have no astrological knowledge or experience in this moment. I will give you the tools to continue the path of becoming a pro astrologer if this is in your heart. This program can either be the beginning or the final stage for you to go into the world and get amazing clients.

Yes! It’s possible to pay in 2 or 6 instalments. 

After payment is completed, you will have access to the program for 1 year. Refunds are not possible. To find out if Cosmic Mastery is right for you and your needs, you can plan a free discovery call.

First of all I would like to thank you for the wonderful 6 week program. I really enjoyed sitting with you every morning and learning from you. I have been following you since 2019 and I really wanted to work with you back then and 3 years later I got the chance. Your knowledge, your presence, the PDFs received and your book recommendations are on point! Unfortunately, 6 weeks went far too quickly. But like I said before you are my favorite Astrologer 🌙 I wish you the best of luck with the other students who will come out of your journey just as richly as I did.

These 6 weeks with Josie were exactly what I needed to learn about Astrology at an enjoyable pace. She taught me everything I wanted to know. Josie is super patient and understanding and therefore a very good teacher. She explains everything very clearly and answers all your questions (even outside of class). Once you have finished these 6 weeks of lessons from Josie, you can apply Astrology in your own life/business with great confidence. For me it really isn't over yet, because I just want to learn more now :) Thank you dear Josie, for letting the astrological flame in me grow into a big, warm bonfire.

I am extremely grateful for the past 6 weeks and I have really learned a lot in a short period of time. Josie has a very nice energy and she explains everything well. I also really liked that she was always ready to answer questions and that I received everything as a nice handout. The personal attention allowed me to really focus on what I wanted to learn and Josie guided me well in this. In addition to what she taught me during the sessions, she also gave me many tools to continue working with astrology myself. I can't wait to start using astrology!

Josie is a great astrologer. I found it incredibly valuable to learn the first tricks of the trade from her. She has so much knowledge and shares it with so much love & enthusiasm. She totally infected me, haha! The theory makes the sessions very practical and applicable, so you can get started right away with minimal knowledge. This bit of awareness is such a wonderful addition to my life, and even to my business. Thank you Josie! 🙏🏼
