Who I Help

I help high-achieving women who feel overwhelmed by the demands of their personal and professional lives. These women often struggle with stress-based habits such as overeating, overworking, excessive worrying, or people-pleasing. They may feel disconnected from their bodies, distant in their relationships, and unsure of how to reignite their sense of passion and purpose. Many long for balance, freedom from negative self-talk, and the ability to truly enjoy the lives they’ve worked so hard to build. I am here to help them move past these challenges and reclaim their confidence, connection, and vitality.

What I Do

I guide women to transform their stress into lasting well-being and joy. Through one-on-one coaching and my signature program, Stress Less, Thrive More, I help my clients reconnect with their bodies, nurture meaningful relationships, and rediscover their inspiration and passion. Together, we release the habits and patterns that keep them stuck, introducing practical tools that create immediate relief and lasting change. My work supports women in feeling at ease in their own skin, present in their relationships, and aligned with their deepest values, creating a ripple effect of positivity in their lives and beyond.

Isabelle's Story

I grew up in Switzerland, surrounded by stunning beauty, but marked by chronic trauma. To cope, I turned to perfectionism, believing success could shield me from pain. This determination led me to excel academically, earning two master’s degrees—one in Child Development from Tufts University and another in International Relations and Communications from Boston University.

My experiences of trauma instilled in me a profound empathy and a determination to help others heal their own wounds. I earned an energy healing degree in Brennan Healing Science and became a licensed marriage and family therapist in 2005.

Early on, I established myself as a trusted and sought-after therapist, specializing in eating disorders and body image healing. My therapy practice merged psychology and spirituality, focusing on the whole human being. Within a few years, my practice expanded internationally and sustained a 6-month waitlist.

On the outside, it seemed as though I had “made it”—a respected clinician, lecturer, and mother of three. But the weight of 55+ hour work weeks and juggling roles as a therapist, wife, and mother eroded my health and marriage. Constantly overwhelmed, I lost what mattered most.
In 2013, my husband and I divorced after 24 years of marriage. Devastated and diagnosed with “adrenal exhaustion,” I hit rock bottom, physically and emotionally. Years of overworking had stripped me of joy and life force.

Determined to rebuild, I sought peace and well-being, investing tons of money and time in mentors and programs. Yet, none offered the transformation I longed for. I realized, “If the tool I need doesn’t exist, I’ll create it myself.”

Over five years, I developed a simple Methodology targeting the root cause of burnout. Testing it on myself, I was astounded. For the first time in decades, I felt vibrant, joyful, and at peace.

This transformation also healed my relationship. My ex-husband and I reconciled, writing a new chapter in our love story. I began sharing the Methodology with therapy clients, who experienced similar life-changing results.

Today, I teach this Methodology through 1:1 coaching, group programs like Stress Less, Thrive More, and corporate initiatives like The Stress Reset. Are you ready to take the first step toward a vibrant, stress-free life?
