About us

4 Seasons Retreats

4 Seasons Retreats are mini-getaways fully dedicated to self-care and well-being in each of the seasons. Marjolein (MDR Happy by Nature) – and Melanie (SOL- Yoga with Melanie) have united their different expertise and specialisms to ensemble a holistic program filled with movement practices, nutrition, outdoor life coaching and inspiration from nature.

When we live in harmony with nature and the flow of the seasons, we live in better harmony with ourselves too. Each season requires a different approach to self-care, in order to support ourselves optimally.

Four times a year, our retreats help you flow through the change of the seasons with grace and ease and in connection with your inner-self.


Marjolein de Ridder

Nice to meet you! I am an outdoor life coach and running therapist. It is my mission to empower people to be the best version of themselves.

I am the founder of MDR Happy by Nature, which offers coaching, trainings, workshops, retreats and blogs, all focussed on how to live a happy, healthy and meaningful life, inspired by nature.

Outdoor life coaching uses the environment to find answers to important life questions, such as: What makes me happy? What do I want to achieve in this life? Being in nature has a positive effect on your body and mind. You can get away from everyday worries and reconnect with what is really important to you.

On my blog Run with Marjolein, I write about my passion for running and what we can learn from running about the art of living and mental resilience. I offer running therapy to literally and figuratively bring movement into your personal transformation process.


Melanie Fissendjidis

Hi there! I am a certified Yin and Strala yoga teacher and founder of SOL – Yoga with Melanie. I guide (group & private) yoga classes, workshops, retreats and in-company vitality programs. As a copywriter I also enjoy blogging about a lifestyle of well-being and gratitude.

My yoga practices are all about moving in a way that feels good to you. By slowing down, softening, and playfully exploring your body & mind, you’ll find space and time to tune into yourself.

How are you really doing right now? Where can you feel the gentle rising and falling of your breath? How can you support your body best? And can you respond to that?

Helping others to work with their body, mind & soul, rather than against themselves: that’s my purpose. So that we can feel supported, light and at ease: both in our yoga practice and beyond.
