Maarten Oversier has now worked as a reincarnation therapist for more than 25 years. His practice diary contains more than 15,000 sessions.

Maarten has had several teachers, including tribal elders, medicine men and women and "Elders" from North American and Canadian First Nation people. They have taught him especially about the importance of working with the ancestors, and carrying this knowledge forward in today's time of immense change.

Below is a tribute to these wise people.

The many flowers represent his clients from whom he ultimately learned the most.

Maarten has been giving lectures, trainings and workshops on these topics for years at home and abroad. He also teaches at various training institutes in the Netherlands, Germany, Spain and in the reserves of the Iroquois First Nations in Canada.

Maarten is graduated from the SRN (School for Regression/Reincarnation Therapy). His practice has been in existence since 1996.
