The Rowan Tree Reiki
Reiki Services & Certification Courses
Dirk is Rhiannon’s husband. Dirk is an engineer and regulatory technical specialist with extensive experience in emissions compliance, vehicle certification, and automotive R&D across leading OEM environments including Toyota. His background spans emissions testing, combustion, hybrid and electric vehicle certification, and regulatory alignment with CARB, EPA, and global emissions standards. During his time at Toyota, Dirk worked under the mentorship of David Hermance, widely recognized as the American father of the Toyota Prius. In this role, he supported early hybrid vehicle development and certification efforts, including SOC-based test procedures and emissions strategies addressing cold start and intermittent engine operation challenges. During his spare time Dirk enjoys helping Rhiannon with her Reiki events. He also is a RMT, CSHP and studied mind-body based modalities at IPSB in 1995. He plays an ancient wind instrument called the Didgeridoo, said to be the first man made musical instrument on Earth, well-known for its deep resonate and calming frequencies. When he is not busy working, you might catch him playing at one of Rhiannon’s events.
