On this episode of The Trauma Therapist Podcast’s Guest Host Series, Christina interviews Sarah Stasica, the founder of Medical Trauma Support and host of the Medical Trauma Support Podcast.

Sarah Stasica is a trauma-informed practitioner, mental health peer specialist, and somatic educator committed to helping both clinicians and individuals recognize medical trauma for what it is and respond to it with the nervous-system-informed care it deserves. Sarah supports people on their healing journey and clinicians looking to deepen their trauma-informed practice through education, peer support, and somatic approaches that honor the body's wisdom.

We discuss the lived experience of navigating Lyme disease, sharing stories of loss, resilience, and the search for answers in the face of complex symptoms. Through personal and professional reflection, we connect with the challenges and triumphs faced along the journey toward healing and understanding.

Questions arise about why some people become gravely ill while others remain symptom-free after similar exposures, prompting us to re-examine the intricate links between trauma, nervous system regulation, and chronic illness. We learn how even the smallest bacteria can transform our lives, discover surprising facts about testing and healing, and find hope in stories of transformation and renewed purpose.

Caitlan Siegenthaler and Christina Kantzevelos realized that they both had grief experiences at their weddings.

So they recorded this episode to explore questions like:

• What about times when you are unexpectedly grieving?

• What happens when joy and sorrow show up at the same time?

• What do we do when the way people show up for big events surprises us or catches us off guard?

This podcast episode is for you if a relationship changed after you got married or if you’ve felt joy and sorrow in the same day or hour. It’s a conversation that we wish happened more often…

On this episode of The Trauma Therapist Podcast’s Guest Host Series, Christina interviews Alanna Brennan. Alanna  is a Womb Worker, Vocal Coach, and Somatic Practitioner devoted to helping women reclaim their Divine Feminine power.

What if your body isn’t broken… but responding intelligently to a life that doesn’t feel like yours? In this Reproductive Rebel conversation on SZN 5, EP 31, Adrienne Irizarry sits down with Christina Kantzavelos to explore the often-overlooked truth: your mental and emotional authenticity directly shapes your reproductive health.

We go beyond surface-level “stress” conversations and into the deeper terrain— where nervous system regulation, identity, partnership dynamics, and truth-telling all intersect with fertility, hormones, and cycle health. This episode is for the woman who feels “off” in her body… for the couple trying to conceive without clear answers… and for anyone ready to ask: Where am I not being real—and what is it costing me? Together, we explore:

• Why authenticity is a biological need—not a luxury

• How chronic emotional suppression disrupts hormones + cycles

The nervous system’s role in fertility for both partners How misalignment in relationships impacts conception *The hidden cost of being “high-functioning” but disconnected

• What it actually means to feel safe in your body again

This is not about doing more. It’s about becoming honest enough that your body can finally exhale. Because a regulated body can receive. A real life can sustain. And readiness isn’t forced—it’s felt.

Micro Balance Health Products has a conversation with Christina on Relational Dynamics in Mold-Affected Homes.

During the conversation, Christina shared powerful insights, including:

• Why unresolved environmental stressors—like mold exposure—can influence nervous system responses

• Practical ways to build internal safety, self‑trust, and emotional regulation

• How to identify relational loops that keep you stuck and how to gently shift them

• The role of daily self‑reflection in healing and creating new relational dynamics

She also introduced her Begin Within Today Symptom Journal, a guided tool designed to help you track patterns, regulate your system, and support your healing journey.

On Episode 119 of The Real Women Real Business Podcast, Shauna Lynn Simon sits down with Christina Kantzavelos.

Christina explains how survival mode shows up in high-achieving women, including overfunctioning, people pleasing, perfectionism, freezing, and fawning. She also shares why boundaries can feel impossible to hold when the nervous system does not feel safe, and what it really takes to create a business that supports your health instead of depleting it.

Listeners will walk away with practical nervous system tools, a more compassionate lens for burnout recovery, and permission to redefine success in a way that protects their capacity, relationships, and wellbeing.

In this episode of The Reproductive Rebel Podcast, Adrienne Irizarry and Christina Kantzavelos explore the deeper truth beneath fertility struggles: your nervous system is the gatekeeper of conception.

Because the body doesn’t prioritize reproduction when it feels under threat—whether that threat is physical, emotional, relational, or internal.

This conversation reframes fertility through the lens of regulation, not restriction.

Through receiving, not forcing.

We move beyond symptom management and into the energetic and physiological conditions that allow the body to open.

Chronic Illness & the Nervous System: Healing the Mind-Body Connection with Christina Kantzavelos

What if chronic illness isn't just something happening to your body, but a signal that your whole system — mind, body, and nervous system — needs attention? In this episode of Thursday Tea with Sami, Dr. Samia Estrada sits down with Christina Kantzavelos, a trauma-informed therapist and holistic practitioner who specializes in chronic illness, nervous system regulation, and mind-body healing.

Christina's path into this work began far from where she expected — doing humanitarian and disaster response work internationally. After contracting Lyme disease, co-infections, and mold-related illness while working abroad, she went from a hyper-independent "Mother Teresa" type to needing help with basic daily care. That experience became the foundation for the integrative, somatic, trauma-informed approach she now offers her own clients.

In this conversation, Samia and Christina explore:

• Why nervous system regulation is foundational to physical healing, and what happens in the body when we're stuck in chronic fight-or-flight

• The deep, often-overlooked connection between unresolved trauma, chronic stress, and chronic illness

• How the post-traumatic growth that can come from chronic illness — and why most people who've been through it wouldn't change their journey

• The grief and identity loss that often accompanies a chronic illness diagnosis, and why "going back to who you were before" isn't always the goal

• What's missing from traditional, fragmented models of healthcare, and why treating symptoms isn't the same as treating root causes

• How isolation shows up for people with chronic illness, and practical ways to rebuild genuine connection and community

• Simple, accessible nervous system tools listeners can start using today — including breathwork, tapping (EFT), visualization, and somatic movement

Whether you're navigating a chronic illness yourself, supporting someone who is, or simply want to understand the powerful link between nervous system health and physical wellbeing, this episode offers both validation and practical, gentle next steps.

On this episode of The Trauma Therapist Podcast’s Guest Host Series, Christina interviews Lauren Auer. Lauren Auer is a Trauma Therapist who has built a community of nearly 200,000 followers by sharing what she's learned from seeing trauma from every possible angle.

Lauren's path into trauma work was unintentional. What started as a graduate school internship at an agency working with both juvenile offenders and abuse victims turned into a career-defining passion.

Lauren is trained in EMDR, certified in Brainspotting, and holds certifications in Somatic Trauma Healing and Compassion Fatigue. Her approach reflects what she learned in her early years from working: every person's trauma looks different, so every person's healing needs to look different too.
