Our Mission & Approach

At Blackhearted Story Studios, we started from humble beginnings that have carried into our business today. As our founder, Massiel, tackled the roads of writing, publishing, and life, she discovered the foundations that eventually led to the mission of this business: to empower the voices of all women,  using stories as a platform to grow in healing, wealth, business, and confidence.


We continue to live that each day at Blackhearted Story Studios as we help women write, publish, and market their books to the world. We approach our clients and their work with the following values at the forefront.

Empowerment

We believe the voices of those in the minority should always be shared and lifted.

Stories

It is through stories that we share our laughter, joy, grief, and inspiration. Through stories, we can change the world.

Empathy

Every writer is different. We believe that our approach to each writer should mimic the stories to each book: with uniqueness.

God-led

The Divine has led us here and we use those foundations to cheer on our writers. We welcome all writers; of all practices and beliefs.

- MEMOIR WRITER

I’m Massiel Valenzuela-Castaneda.

As a multifaceted individual, I wear the hats of a podcaster, book coach, and an accomplished writer, proudly serving as the CEO of Blackhearted Story Studios. My academic journey led me to a Bachelor’s degree in English with a focus on technical writing from San Jose State University. Fueling my passion for creative expression, I immersed myself in various writing courses and workshops, including the esteemed CSU Summer Arts program.

My literary journey has been marked by notable achievements, including the prestigious James Phelan Award for my outstanding creative writing. Transitioning into the realm of software technical writing, I honed my skills and later ventured into the realm of book coaching. Over the years, I’ve collaborated with remarkable authors, delving into both faith-based literature and the fascinating world of science fiction. Notably, I served as a manuscript reader for a prominent New York literary agency, gaining valuable insights into the intricacies of the publishing world.

Around 2018, I embarked on the journey of publishing my own works, a venture that inspired the establishment of Blackhearted Story Studios. This venture was born out of a profound realization that our voices are as crucial as the stories we tell; they deserve to be shared with the world.

Blackhearted Story Studios exists as a nurturing space for writers to not only create but also publish and market their literary works. I am dedicated to fostering an environment where writers can cultivate their experiences, build businesses, and explore everything in between. My mission is rooted in the belief that every voice deserves a platform, and through this endeavor, I aim to empower writers to grow and thrive in their creative pursuits.
