The Foundation of Your Development

In 1997, Geologist Scott Wallace established a geo-environmental practice in Bend, Oregon for a large national engineering firm. The practice flourished with the addition of numerous multidisciplinary engineering, earth science and construction service professionals, and soon become one of the recognized leaders in applied earth and environmental science solutions throughout the Pacific Northwest. Wallace purchased the practice in 2010 and renamed the firm The Wallace Group, Inc.

My Wallace Connection

I am an earth scientist through and through with more than 33 years of experience working primarily on environmental, geologic and groundwater resource studies. I founded Wallace Group in March 2010 on the fundamental philosophy that we work to live, not the other way around. Over the years, I have learned to apply my observational skills together with a knowledge of the Pacific Northwest’s geosystem, specifically the High Lava Plains and Cascade Range of central Oregon. I enjoy sharing this information with clients and incorporating that knowledge into successful projects.

My Perfect Day

It starts with hot coffee, the newspaper, and a hearty breakfast. Next up is any kind of outdoor or sporting adventure, followed by happy hour and dinner on the deck with friends or family.

My Wallace Connection

I started as a commercial Oilfield Bell/Saturation Diver and then as a Nondestructive Testing (NDI) Inspector, so I have years of experience in a wide variety of applications and environments (Oilfield, Pipeline, Construction, Marine, Industrial Fabrication, Military, Aerospace, Performance Sports). In the last 20 years, my roles have included Sales/Marketing Manager and then Operations Manager of a Testing Lab in Seattle, and the last 10 years at the Boeing Company working in the Quality Systems side of things for the new 777X Composite Wing Center. It’s kind of a unique background, but I like solving technical problems and working with people to find solutions.

My Perfect Day

One spring day, my brother and my best friend and I climbed up to the top of Mount Bachelor (before the summit lift) and sat for a while admiring the view of Elk Lake. When we finally decided to put our skis on and head down, we looked and there wasn’t a person on the runs, only a snow cat finishing up the grooming. We still all remember the longest “perfect” ski run of our lives with absolutely no skiers on the mountain, followed by a big plate of Nachos when we got back to town of course.

For a kid from Bend, how great is it to earn a Bachelor’s degree in geology, then be able to find work right here in my hometown, close to family? I’ve been with Wallace Group for about two years and love wearing multiple hats in both the field and the office. We have a close-knit group both in and outside the office.

My Wallace Connection

My background is in accounting and I pride myself on being detail-oriented and organized. When we first moved to Bend I was working remotely for another company, so it has been nice to work with some really great people and learn a whole new industry. I really enjoy seeing the projects we are working on around Bend and knowing that we are helping to grow and improve our community. I assist the business administrative manager with new project set-up and field calls from contractors, superintendents, etc. on projects who need to schedule us for inspections and testing.

My Perfect Day

It would probably start with a cup of coffee and ocean roll from Sparrow Bakery. Then a walk or run along the Deschutes River. Paddle boarding on the Deschutes River up by Dillon Falls. Finally, we would have some friends over for a fire and make pizza in our wood fired oven.

I brought my uncommon knowledge of earthquake engineering, slope stability, and engineered excavations to Wallace Group about five years ago. Today my expertise includes construction on volcanic soil and rock, soft soil sites, shallow and deep foundations, and forensic work. I love working closely with other local design professionals on a variety of ground conditions from soft soil to hard bedrock. There is a new challenge for every site and each project is unique. I have been a board member of my engineering honor fraternities, the San Francisco Geo-Institue, and now Professional Engineers of Oregon.

My Perfect Day

Taking my boys to one of the many lakes to swim and paddle board, bring our own picnic lunch, dig in the sand, watch them find insects and frogs, and finish the day off with some ice cream.

I’m a Hoosier originally from Indianapolis. I joined the Wallace Group in June of 2019. I love the variety of work and relish being at the foundation of Wallace Group’s product. My specialty is performing strength testing for concrete specimens as well as compaction and gradation tests for soils and aggregates, probably because I understand the fundamentals of soil mechanics. In addition to being a good prioritizer and multitasker. I’m always available to assist field staff that need help or info.

My Perfect Day

Going climbing, riding bikes to a brewery to meet friends, cooking and eating outside on our patio, going on tons of walks with our dog. That’s pretty much every summer weekend here.
