First about CwM. Why CwM? 

A cwm, pronounced "koom", is the name of a geologic landform; a cirque; or bowl shaped valley just below a mountain peak (see our Home Page). The water caught in these high mountain lakes and glaciers is the origin of most of the available water supply in the Western United States. The letters of our name also stand for Complete Water Management, which is what we do.

Water touches every facet of our lives, our businesses, and our future.  CwM provides expert services related to water supply, be it surface water or groundwater rights, water management and conservation planning, or wastewater compliance and permitting.  So whether you say "koom"  as in where we like to play or  "C-W-M",  where we like to work, you are correct. 

We work in environmental consulting because we have an intimate connection with the natural environment. We are passionate about finding a sustainable balance between the natural world and the demands of the human built environment and driven to meet these challenges.

Bob is a water and natural resources consultant with over 20 years of experience.  His career began in 1987 working for Syracuse University as an environmental chemist at the USFS Hubbard Brook Experimental Forest doing experimental design and water quality analysis for research on acid rain in the White Mountains of New Hampshire. His interest in water, water quality and groundwater led him to Seattle in 1991 to start his consulting career as a Hydrogeologist.

He is currently a Registered Geologist (RG) and Certified Water Rights Examiner (CWRE) in Oregon and Washington, and is a Licensed Hydrogeologist (LHG) in Washington.   

Since 1991, Bob has worked as a consultant on contaminated soil and water clean-up, groundwater development, biosolids permitting and operations, water right acquisition, water right renewal, hydrogeologic exploration for water supply, dewatering and water quality for mine development and operation, water conservation planning, thermal and renewable energy site selection and permitting, open pit mine expansion permitting, pipeline permitting, and expert testimony in support of water right extensions.  Bob has also worked as a office manager, northwest regional manager, and has managed two start-up operations to grow profitable offices for two previous corporations. 

Bob enjoys running in strange places and in all weather. When not in the office he is known to fly fish, ski, or attend school sporting events.  He can often be found cheering on his daughters' lacrosse teams.  A confirmed Syracuse University sports fan, Bob bleeds orange (i.e. Syracuse Orangemen) during the college football, basketball, and lacrosse seasons.
