Authority Stories with Natassia Miller

From finance to sexology

Hear from an entrepreneur who has been through coaching with me, and grown their Authority and their business as a result.

This is an extra special one for me, having met Natassia back in 2021 and followed her journey closely, first as her coach through this transition and into 2020, then as simply an admirer of what she’s gone on to build year on year since!

Enjoy!

Natassia Miller is a Brazilian sexologist who helps women and couples build a sex life and relationship they look forward to. She is the founder of Wonderlust, a sexual wellness company offering tools, education, and exclusive events. Based in New York City, Natassia’s work blends research, psychology, and mindfulness. Before becoming a sexologist, she worked in finance. Her expertise has been featured in Cosmopolitan, Glamour, GQ, and NBC.

Q. Tell us about your business, your mission and Authority area?

I’m the founder of Wonderlust, a sexual wellness company helping women and couples build a sex life and relationship they look forward to. My work bridges science and sensuality, combining research-based education, mindfulness, and real conversation to transform how people experience intimacy.

My area of authority is in desire and sexual communication. I teach individuals and couples how to better understand their unique desire styles, break free from shame, and create space for pleasure that feels authentic and sustainable.

Wonderlust’s mission is to help people feel more confident, connected, and fulfilled in the bedroom—and beyond—because when we own our pleasure, it impacts every part of our lives, from our relationships to our sense of self.

Q. How has your authority evolved since your coaching with Ellen?

Working with Ellen was a turning point in my career. She helped me gain the confidence and clarity I needed to articulate my mission, vision, and next steps with precision.

Since then, my authority has evolved from having a general passion for intimacy education to leading Wonderlust today with a very clear purpose. That clarity has gone on to shape everything from my speaking engagements and workshops to how I design educational tools and experiences that make sexual wellness more approachable and empowering.

Q. Why did you choose to have coaching with Ellen, specifically?

I'm a solo founder and felt very alone in this journey. I also wanted to make sure I succeeded, and Ellen's direct approach fit with my style, so I pulled the trigger.

Q. What did coaching with Ellen unlock for you in terms of your business, clarity or authority?

Coaching with Ellen unlocked a deep sense of confidence and direction in my work. Before, I struggled to translate it into a clear message and business strategy. Through our work together, I gained clarity on who I serve, what I stand for, how I should spend my time, what I should delegate and how to communicate all of that with authority.

Plus, she made me feel like I had a partner in this journey, which was very comforting.

Q. What was an unexpected takeaway from the coaching?

I liked how Ellen pushed back and always kept me in check. She is also very sharp, present and focused during our meetings, which inspired me to show up with similar energy to make sure we got the most out of our time together.

Q. What are you proudest of in your business since coaching?

What moves me most is hearing from both clients and followers how my work has helped them have breakthroughs in their sexuality and sex lives.

Of course, hosting the Sex Talks event series at Soho House New York and being featured on NBC, Cosmopolitan, Glamour and other leading outlets have also been very special.

Q. What's your vision for your business in the next few years?

My vision is to transform how women experience and talk about sex. Over the next few years, I’m building a global community where women can learn, connect, and feel empowered in their pleasure—through expert-led education, events, and real conversations that normalise what’s too often left unspoken… I'm very excited for that.

Q. Any advice you might have for someone reading this, who wants to become an authority in their space?

You're ready when you decide you're ready, and confidence is learned by doing.

In retrospect, I held myself back from a few key opportunities because I thought I needed to be better prepared. I wish I hadn't and today this mantra has opened so many doors for me.
