Cristina was born (1985) and raised in Asturias (Spain). She got certified as nurse in 2006 and started her training as midwife in 2007 in a public hospital. During that time, she realized that obstetrics in many places was dehumanized and that professionals often took away the unique birth experience for a woman by performing unnecessary interventions during labor. Therefore, after getting certified as a midwife, she chose to follow a very natural approach when attending labors and births.

Cristina started working in Edinburgh (Scotland), where she was attending home births with a team of midwifes. Later, she worked in a birthing center in Lima (Peru). Here she received furthermore trainings in music therapy, respectful pedagogy and podal reflexology. In 2014, she moved to Venezuela for one year, working in the same field and also offering lactation consultations. Cristina received a training in prenatal yoga as well.

She has been participating in a continuous formation at the Superior School for Traditional Chinese Medicine (TCM) in Madrid since 2015. Cristina is certified as “Técnico Superior en Medicina Tradicional China y Acupuntura”.

Jonathan was born (1973) and raised in Springfield (Massachusetts USA).

After finishing high school in 1991, he studied sports medicine and sports physiology at the University of Connecticut from which he graduated in 1995 with a Bachelor of Science (BS). Subsequently, Jonathan worked for two years in a physiotherapy practice and a rehabilitation clinic, until he realized that conventional rehabilitation was not his vocation. Therefore, he decided to expand his education and studied at Springfield College (Massachusetts, USA) from 1997 to 2000, where he was awarded the Master of Science (MS) in physiotherapy.

In 2000, Jonathan had the opportunity to work and study directly under the guidance of the Founder of the Integrative Manual Therapy (IMT) – a specialized branch of osteopathic manual therapy. It was an experience that has guided and shaped him personally as well as professionally.

The roots of his clinical work are based on the Integrative Manual Therapy, being a unique fusion of osteopathic manual therapy and bioenergetics. Jonathan has expanded and supplemented his training in manual medicine with several complementary healing approaches such as acupuncture, auricular therapy, applied kinesiology, NAET, biomagnetic pair therapy, the Yuen method, Sintergetica and Reiki.

“Orientation – Movement – Balance” are the three principles that Jonathan considers to be the foundation of healing and well-being, and it is the motto on which he bases his activity. He tries to help his patients to go their own way, to use their own potential and achieve their personal goals.

Jonathan has been living and working in Madrid since 2003, and since 2016 he is a member of the team at the IWHCM.

At the IWHCM he applies a combination of the above techniques in order to treat orthopedic problems as well as systemic disorders such as hormonal or emotional imbalance.

Laura was born in Madrid (Spain) in 1977, where she also grew up. She received both her degree in chemistry in 2000 as well as a Master of Analytical Chemistry in 2002 from the University San Pablo CEU in Madrid. She wrote her doctoral thesis on rheumatic autoimmune diseases at the University College of London (UK), and subsequently worked in research at the University of Basel (Switzerland), the University of Rochester (US) and the University College of London (UK).

Laura considers the time she spent in research as very important for her current role as a homeopath as it gives her a better understanding of the biology of the human body and the mechanisms of various diseases.

The need for a medicine that does not separate local symptoms from the whole organism of the human being, a medicine that has no side effects and that is built on a holistic basis sparked Laura’s interest in homeopathy and led her to study this complementary medicine that she has been familiar with ever since her mother took her to a naturopath when she was little.

In addition to her work at the University College of London, Laura completed a three-year program at The Center for Homeopathic Education at Middlesex University, which she completed in 2010 as a certified Homoeopath. Since then she has worked in several clinics in London and Madrid.

Since 2018, Laura is a member of the IWHCM, where she mainly takes care of women, children and babies.

Belén was born in Madrid (Spain) in 1964, where she also studied sociology and political sciences at the Complutense University. Later, she studied psychoanalysis at the University Pontificia of Comillas.

After many years of working in finance, she felt the strong need for a radical change in her professional life. She decided to leave the business world and to become a psychoanalyst.

Belén considers these years of working as a psychoanalyst and of always being an active member of the European Foundation for Psychoanalysis based in Paris as an important phase in her life of many lectures, conferences and publications… in short: as years of unstoppable personal growth.

Belén sees psychoanalysis as a way to understand one’s life in the context of one’s uniqueness that accompanies us and that also distinguishes us. It helps us to reduce what inhibits us and to maximize what boosts us.

Sharing her personal experience of psychoanalysis, she says that at some point she found herself being on stage of a theater, writing books, integrating, balancing everything and, in summary, enjoying growing personally. Suddenly a whole new world of thus far undiscovered potential for personal achievement appeared.

It seemed that at first psychoanalysis had only been a change in her life, but then it actually turned out to be changing her life.

Belén has been working as a psychotherapist at IWHCM since 2017. She only offers therapy in Spanish.
