Hilah and David Leitner established RHYDL to provide solutions for issues impacting our world. 

Under the auspices of RHYDL, Dr. D. and Hilah are working to educate and change their world through a spectrum of projects. 

Hilah and David run lectures, seminars, workshops, sustainability and natural engagement programs, and are on working on several accessibility and inclusion projects. 

The RHYDL online home is still under construction, so this is a temporary home hosted on David’s personal website server. 

Look out for the new website in the near future.
