Miriam Castilla is an International Author & Speaker who inspires self-reflection and offers her audience highly practical take-aways.


Known as THE EFFECTOLOGIST, Miriam Castilla’s passion is saving people from the sea of overwhelm they find themselves in – helping them get unstuck and move forward with confidence.

Her focus is on restoring life balance and reigniting passion with a unique inside-out approach she calls EFFECTOLOGY.

By showing her audience how to leverage the 3 critical keys of  Clarity, Focus & Strategy, she helps them achieve massive shifts in personal effectiveness and discover the limiting beliefs that have been keeping them trapped.

“This will give you the driving force you need to implement some powerful strategies and move forward with clarity and confidence.”


Miriam warmly engages her audience as she openly shares her personal story.

“It’s about learning how to balance the Yin with the Yang – your OUTSIDE WORLD with your INSIDE WORLD – and knowing what to STOP focusing on that’s been holding you back!”

 Kind Words:


I have been lucky enough to see Miriam Castilla present several times now for all-female audiences. She has such a calming yet professional style that I could listen to her for hours. 
Miriam ran her Money MO course for our exclusive Property Women members. Her understanding and knowledge was spot on. I found myself nodding along and recognizing my own behavioral patterns around money. 
This talented lady included a meditation session at the end with some really interesting revelations – all the feedback has been really positive.
If you get the opportunity to see Miriam present, jump on it – it might just be life changing.
Jo Vadillo, Property Women

The 2015 International Rural Women’s Conference was fortunate to have Miriam Castilla as a panelist. Miriam spoke with honesty, compassion and empathy as she shared her leadership journey with the international and national delegates.

Miriam is an interesting, intelligent and accomplished speaker who has the ability to engage her audience as she weaves the inter-relatedness of leadership and finance by challenging us to believe in ourselves and take charge of our own lives.

We gained much from listening to Miriam. Her skills and knowledge were much appreciated.
