Introducing The Mycelium:
Thought Leadership Accelerator for Leaders in
Consciousness, Climate & Mental Health

Catalyzing Visionary Voices Guiding Humanity Through Crisis, Healing & Transformation

Hi! I’m Marissa, and I help conscious leaders grow their awareness, connections, and impact for results.

For 20 years, I’ve helped values-aligned entrepreneurs, executives, and startup teams grow from idea to inception to leading brands, advancing business results.

There are typically three strategies for mycelial growth—let’s discover yours…

1: Define Your Bold & Timely Differentiators—Rise to the Top

In my role as PR & Brand Director for Nushama, we built a foundation that drove exponential awareness growth by leaning into what made them unique. Together, we:

  • Clarified purpose through “Articulate Your Why” framework

  • Launched a ketam*ne center with strategic media outreach

  • Rebranded at the intersection of science and spirituality

  • Secured 200+ media stories and 5B+ impressions (NYT, GMA, WSJ)

  • Attracted a steady flow of new members

The key? Bold, clear differentiators woven into your communications.
You’ll use this same process to define what sets you apart—and amplify it to attract aligned opportunities.

2: Build & Educate Your New Market

From psychedel*c therapy and regeneration to social innovation and coworking, I’ve helped shape emerging markets by naming what’s next and building the narrative and ecosystem around it.

In 2008, I co-founded Green Spaces—calling it “shared workspace for environmental entrepreneurs” before coworking was mainstream. That early clarity positioned us as a top community hub.

In this accelerator, you’ll learn to:

  • Spark demand for what doesn’t yet exist

  • Name and frame what’s emerging in your space

  • Craft language that educates and attracts

  • Position yourself as a trusted voice

  • Build traction through clarity and aligned messaging

What future are you shaping? Let’s amplify it.

3: Create Your New Ecosystem — Attract Growth

When a client once said, “Environmental problems are human problems,” it shifted my lens—and led to the birth of an emerging movement. I’ve since built a values-aligned ecosystem bridging climate, consciousness, and social change. In the accelerator, I’ll help you do the same.

What I’ve Built:

  • Founded PSYCA, now a 13,000+ strong global community

  • Featured speaker at The New York Times Climate Forward, SXSW & Psychedel*c Science

  • Earned 100+ media stories about PSYCA

  • Recognized as a hub at the intersection of climate and consciousness

  • Continuously engaged by researchers, collaborators, and media worldwide

What You’ll Learn:

  • Identify your key intersections

  • Build a resonant, values-driven ecosystem

  • Attract aligned partnerships, media, and momentum

Weekly Coaching on Next Steps to Achieve these Strategies…

Thought Leadership Advisory: Publishing, Podcasts, Speaking & Visibility Strategy

Learn how to amplify your ideas through the channels that matter most to your audience — with intention, timeliness, and consistency. Whether you're just starting, or ready to expand your visibility, you'll get personalized support to expand your reach and influence.

You’ll receive coaching on how to:

  • Identify platforms aligned with your mission — from trusted media to niche podcasts

  • Share your story in a way that feels authentic and moves others to action

  • Craft headlines, bios, and messages that attract and build relationships, and maintain relevance

  • Pitch strategic speaking engagements and thought leadership opportunities to build your personal or organizational brand awareness

  • Grow your presence as a leading voice in your field or niche

Execution Support: Using AI Ethically, Efficiently

AI can amplify your thought leadership — when used with care, intention, and integrity. Learn a values-driven approach with a trusted PSYCA partner, using AI as a creative ally to enhance (not replace) your voice.

You’ll learn how to:

  • Streamline your workflow with AI for drafting, brainstorming, and content creation

  • Preserve your tone and values in every AI-assisted output

  • Maintain the human touch while integrating AI

  • Avoid common pitfalls like overuse, generic messaging, or voice dilution

  • Choose smart tools and prompts to save time without sacrificing nuance

This is about using AI in service of your message — not at the cost of it.

Polycrisis Positioning: Message Your Timely Work for a New Era

We’re living through overlapping crises — from climate to mental health to social systems. This era demands clarity and coherence. In this coaching circle, you’ll craft messages that meet the moment and reflect your unique contribution.

You’ll receive support to:

  • Articulate your relevance in this historic era with bold, timely messaging

  • Refine your bio, offerings, or narrative to show how your work addresses polycrisis challenges

  • Frame your story to resonate with funders, media, allies, and other key audiences

  • Balance urgency and hope without fear-based or hyped language

  • Align your message with your values and long-term vision

Whether evolving your personal brand or reshaping an org’s voice, this is about building a strategy for right now — with integrity.

PR Strategy: Engaging the Media for Awareness

In today’s media landscape, visibility is about more than coverage — it’s about trust, alignment, and momentum. You’ll build a strategy that blends earned and owned media to share your message with clarity and impact.

You’ll get support to:

  • Clarify your story’s value — why it’s timely, credible, and worth sharing

  • Differentiate earned vs. owned media and know when to use each

  • Identify aligned outlets and journalists who care about your domain

  • Craft thoughtful, effective pitches that spark interest and build trust

  • Use AI tools to streamline media tasks while preserving your voice

This is about being discoverable and intentional — so your message reaches the right people at the right time.

You don’t have to go it alone. This accelerator offers warm, intentional introductions to journalists, collaborators, and fellow thought leaders — to expand your reach and deepen your impact.

You’ll gain support to:

  • Connect with aligned media contacts in your area of expertise

  • Grow your network of like-minded leaders and communities for synergy

  • Expand your network with collaborators for cross-promotion or partnership

  • Build social proof through shared content and visibility opportunities

  • Spark ecosystem momentum that amplifies your message and mission

Because relationships are still the most powerful form of strategy — and you’ll leave with new allies, advocates, and visibility.

  • Marissa's coaching helped secure top-tier media coverage — we leveraged it to raise $10 million


    “As my company was looking for Series B funding, we had to show investors that carpooling.com was a tech company with impact and tremendous potential. Marissa's teachings and private coaching were instrumental in helping me reach out to top-tier media with the right tone and angles. We got coverage in The New York Times, FastCompany, and Forbes, quickly. And we leveraged the PR to successfully raise $10 M.”

    - Odile Beniflah, Carpooling (acquired by Blablacar)

  • I gained clarity and focus for my thought leadership, advancing my business goals


    "One of the greatest ways that Marissa adds value is by helping to establish the story rooted in Why, How and What. With her guidance, I published my first book and gained media attention before and after the launch. I had many aha moments that led to the ultimate establishment of my coaching and speaking business. I gained clarity around why I wanted to pursue a speaking career, my specific areas to focus on, and I continued to get different perspectives on how to execute each idea in building my platform."

    - Mellany Paynter, Author, Speaker, Entrepreneur

  • We Reached Our Launch Goals!

    "Marissa gives a great deal of attention to who you want to reach, and what exactly you want to say. She has a deep well of media contacts and was able to help us secure great coverage in Forbes, Thrive Global, and an on-camera interview on Cheddar, and our ‘holy grail,’ a feature story in The Hollywood Reporter. “

    “She's incredibly responsive and supportive. She really makes you feel that she is personally invested in seeing you succeed, and that you have a trusted friend on your side helping you.”

    - Beth Bell, Founder, Green Product Placement

  • I learned a thought leadership strategy that worked for me, and it was easy to execute!

    "In one training session with Marissa, she unlocked a PR strategy and perspective for building my business that I never knew was possible. I shared my goals and struggles, and she recommended simple tactics in line with my skills. I am now getting results with a new plan of action that works for me!"

    Silvia Christmann, I/O Psychology, Leadership Development, Executive Coach

  • I found an immediate ROI with a our newly crafted story

    "I found an immediate value return in Marissa's Articulate Your Why process. Marissa's questions made it easy for me to contemplate and articulate my values. Seeing the parallels between my own Why, my company's Why, and my customer’s Why, was fascinating and enlightening - I always felt the connection, though this reinforced the relationship. Marissa worked with me to tie these pieces together into a cohesive story that resonates. I even used the results of our session in conversations with two stakeholders the very next day!" 

    - Greg Iorio, Founder, Condor

While the focus is on personal brand development, this work ultimately enhances the visibility, credibility, and impact of the leader’s organization.

    If a team member is directly supporting the leader’s communications or public presence, they’re welcome to join and participate on the leader’s behalf. By investing in the capacity of these leaders, The Mycelium also strengthens the organizations, ecosystems, and movements they represent—helping elevate their voices and values in the public sphere.

  • Conscious leaders, entrepreneurs, nonprofit founders, and movement-builders working at the intersection of climate, mental health, regeneration, and systems change. People in adjacent fields are also welcome. Prior media or PR experience is not required—just a clear commitment to serving your community and the planet.

  • Participants are selected based on fit with the program’s schedule and goals, ensuring they have the capacity to fully engage and benefit from the experience. We may also host a brief introductory session to confirm that each applicant’s thought leadership goals align with the program’s offerings.

  • Participants are encouraged to attend weekly 1-hour live Zoom coaching sessions. While recordings will be available for those who prefer to learn asynchronously, the sessions are designed to be interactive—ideal for asking questions and receiving personalized support in real time. To get the most out of the experience, participants should plan to set aside time to integrate insights into their communications and next steps.

  • Proceeds from The Mycelium directly fund PSYCA’s nonprofit mission, including community events, operational costs, and the amplification of conscious, values-aligned thought leadership.

  • We’ve priced The Mycelium to offer strong value while remaining accessible to mission-aligned leaders. At this time, we do not offer formal scholarships.
