O'Donnell & Associates, Inc. is a small business by design allowing us to operate in an efficient manner with low overhead which in turn allows us to pass along savings to our clients. Our permanent full-time staff includes Nell and Dan O'Donnell.

Nell O'Donnell, RN, President and CFO

Nell is the majority owner of O'Donnell & Associates and has control of the "business" end of the firm. Nell's responsibilities include fiscal management, invoicing, health/insurance issues and budgeting. Outside of OAI activities, Nell is a nurse with the Mobile County School system on an "on call basis". In her spare time she invloved with Cursillo, being grandma to Daniel, Samuel, Irene and George and with church activities at St. Pius X Catholic Church.

Dan O'Donnell, PG, Hydrogeologist

Dan, a 1979 graduate of Auburn University (BS Geology), has 39+ years of experience in a variety of geologic fields. He maintains professional geologist registrations in Alabama, Arkansas, Florida, Kentucky and Mississippi with Louisiana pending. He is responsible for the technical aspects of the firm. Since 1990, Dan's focus is hydrogeology; the research, exploration, development and management of groundwater resources. He has formal training in hydrogeology from Oklahoma State University and extensive experience with aquifers in the Coastal Plain. Outside of work, Dan is the past Grand Knight of Knights of Columbus Council #13085, is active in The Men of St. Joseph, Cursillo, and other church activities at St. Pius X Catholic Church. In his spare time he works very hard at spoiling his dog Jonas, being papa to little Daniel, Sammy, Irene and George and enjoys conducting research on three shallow aquifer wells in his back yard.

Additional Expertise

Through teaming arrangements with a variety of firms including 23 engineering firms, six drilling contractors and private individuals. OAI has access to PEs, drilling contractors, wetland specialists, developers, karst geologists, hazardous waste management specialists and a variety of technical support personnel. Again, by not having these highly qualified and experienced individuals "on staff" we are able to keep our costs down while being able to provide their expertise on a project specific/as needed basis.
