About Geo-Marine Technology

Geo-Marine Technology, Inc. was founded by Mr. John L. Rietman in San Diego, California in 1997.  In 2006, the company relocated to Missoula, Montana, where it subsequently assembled a team of several up-and-coming geoscientists to accommodate its expanding client base and service provisions.  The college town of Missoula was constructed within the beautiful and geologically unique mountains of western Montana.  Its scenic location allows us to perform high-quality work without the distractions of many urban centers and imparts an array of recreational opportunities to enjoy with family and friends. 

Now lead by Mr. Rietman and Mr. Beau Pallister, the consultancy of Geo-Marine Technology, Inc. has grown into a team of professionals with more than 40 years of experience in analyzing and interpreting geological and geophysical data.  Each of our highly knowledgeable geoscientists is proficient at completing hydrographic survey projects and Desktop Studies from the ground up.  Geo-Marine Technology is more than another geophysical interpretation company; we are data analysts dedicated to providing our clients with solid scientific support.

Spencer Paddock
In October of 2011, a scruffy Maggot wandered in off the rugby pitch to look over John's shoulder at the kind of work we were doing here at GMT.  Somehow - and it remains mysterious to this day - looking turned to working, and soon we were paying Spencer for his time.  Nearly 5.5 years have come and gone since then, and in that span, Spencer became a valued member of our team, especially with respect to his contributions offshore.  So we're sorry to announce that he is leaving us to pursue new opportunities in Alaska.  Apparently he'd rather be with is his fiancée, Margot, than hang around with us here, and fair enough.  We wish them both every success in their new life, and feel certain Spencer will spread his smile-and-nod across The Last Frontier in no time.  Many thanks for your time and effort with us, Spencer.  We look forward to a time when we might work together again.  Take good care.
