Our specialists

I am Erwin Lagcher, and since 2017, my mission has been to restore as much quality of life as possible to every patient with a chronic condition.

I have been involved in various martial arts since childhood and aim to share my knowledge and experience with my members, as well as with both new and current trainers. Together with various specialists within our company and the medical community, we are able to slow the progression of symptoms associated with a range of medical conditions.

I am Marianne van der Spek, and I have been familiar with Parkinson’s disease since 2010. I realized early on that exercise helps slow the progression of the disease. Since 2022, I have focused specifically on physical relaxation; after all, wouldn't it be wonderful to complement all that physical activity by giving the muscles some extra care through a soothing massage? I also incorporate yoga into my approach, as it is crucial to train stability and flexibility—alongside mobility—when managing this condition.

I am Christéan de Weerd, and my motto is "Strength through connection." As the owner of Power Body Soul and CHRISTEANS, I help people and organizations grow by fostering a balance between physical strength, mental calm, and emotional well-being.

At Power Body Soul, I employ a holistic approach incorporating breathwork, polyvagal theory, boxing coaching, and energy work. Drawing on my training as a breathwork coach, boxing coach and therapist, applied and spiritual psychologist, and my background in basic medical knowledge, I combine science and practice to achieve lasting results.

After 20 inspiring years as an (interim) manager in the Netherlands and Germany, I founded CHRISTEANS in 2018. Here, I leverage my experience in management, coaching, psychology, and boxing to guide individuals, teams, and organizations toward strength, vitality, and growth. Together, we embark on an innovative path filled with development and inspiration.

My name is Lilian Booltink, and I am passionate about guiding people toward their authentic selves and inner strength. With nearly 20 years of experience in yoga and meditation, my journey began with a Sivananda yoga class that felt like coming home—an experience that has permanently shaped my life.

Over the years, I have translated my personal growth into valuable insights, which I share through my unique platforms: *Manusje van Alles* and *Talent*. My approach is multifaceted, combining innovation with depth. Yoga, mindfulness, and Buddhist practices are central threads in my work, enabling me to foster a sense of calm, focus, and awareness.

At Power Body Soul, I collaborate with Christéan de Weerd to offer a holistic approach that integrates boxing, yoga, breathwork, energy healing, and coaching. Drawing on my knowledge of Human Design and the *Kernvisie* Method—and with my upcoming certification as a Living Your Design coach in 2025—I provide tailored guidance to help you embody your unique potential.

My mission? To support people in discovering their own truth and forging a deep connection with themselves.

Physiotherapy should be tailored to the individual patient!

Throughout my career, I have consistently invested in my professional development by taking various courses to further refine my skills. In recent years, I have pursued these opportunities across several different practices. Despite valuable collaborations with other therapists, I felt a growing desire to build something that fully aligned with my own vision. As an ambitious person, I strive not only to help people with their ailments but also to genuinely help them move forward.

My dream suddenly became a reality after I got in touch with a representative from Sportcity. In 2023, I launched my own practice in close collaboration with Sportcity in Capelle aan den IJssel. Ambitious plans are currently underway to expand the practice, which will make my treatment approach available to a wider audience. I am also currently mentoring two trainee physiotherapists who will soon be fully integrated into the team.

In addition to my work at the practice, I serve as the physiotherapist for the v.v. Capelle 1 team. My background in sports has made me well-versed in the various injuries caused by athletic activity. Consequently, my primary goal is to get athletes back on the field as quickly as possible.
