Dennis Wanless


With over 30 years of experience in the industry,

D. R. Wanless & Associates, LLC, has been

providing dependable, first-rate,

continuing professional education classes

for over sixteen (16!) years.


Our classes are created in-house using

our own high quality research and development.  

We take scholarship seriously and

bring you our best possible

knowledge and understanding of

every subject we present.


We strongly believe that teaching and learning

are enhanced when

water and wastewater professionals

have an opportunity to get together

in a classroom setting

and exchange their

real-life experiences and ideas

in-person with their peers.
