The intrepid Human Resources Manager at Wallace Group, Kathy L. Redden is what you might call a “horse person.” She thrives on the back of elegant equines and feels at home out on the trails. She also feels at home at the offices of Wallace Group where she has worked since 2001. Kathy has an easy smile and a feisty sense of humor that may include a pie in the face from time-to-time. Her work experience spans more than twenty years at engineering firms which gives her a unique understanding of what Wallace Group does from a non-technical viewpoint. Kathy is a Bay Area native, but like many people in SLO County, went to school at Cal Poly (English major) and was able to find a good job and never left. Below is our question and answers with Kathy. Wallace Group: Describe what you do at Wallace Group Kathy L. Redden: I’m the Human Resources Manager, involved in recruiting, retention, benefits, reviews, counseling, and whatever else may appear in my doorway. WG: What are some of your favorite activities with WG? KLR: HR isn’t always the most fun job. Thankfully I have great co-workers that make it worthwhile. Any activity that involves laughter is the best! WG: What are you involved in outside WG? KLR: I’m involved with the Atascadero Horsemen’s Club since 1990, and am currently the president. We are celebrating our 50th anniversary this year! We have monthly meetings, monthly trail rides and campouts, and do trail work. Our big event is our annual Toys for Tots ride. I’ve also been involved with the Central Coast Concerned Mountain Bikers for 19 years. CCCMB does trail work throughout the County – trail maintenance and trail creation. I am on their Board of Directors as the Equestrian Liaison, and am the Regional Crew Rep for Santa Margarita Lake. A big project involving CCCMB and AHC is the extension of the Sapwi Trail on the north side of the lake. We’re creating approximately 3 – 4 miles of new trail! WG: Favorite pastime? KLR: Horseback riding (every weekend!) – trail rides and campouts, traveling, reading. WG: Favorite food? KLR: Chocolate! WG: Describe your dream vacation. KLR: Either in the big outdoors, like Africa or Yosemite or Yellowstone, with all the big vistas and animals. Or historical/architectural vacations like going to Turkey, Guatemala/Mexico (visiting the ruins), Europe, etc. WG: What’s your favorite childhood memory? KLR: Going to Yosemite every summer with family and friends for almost 20 years. I feel like Yosemite is “mine” because I have so many memories from being there so much. WG: What is the farthest away from SLO have you been? KLR: Africa, on a horseback riding safari in 2012.

30 Years Before the Mast I was asked if I could unabashedly describe and recount some of our company’s history and more importantly, why I believe we are still here after 30 years and looking forward to the next 30 years! I hope I can describe some activities, projects and clients from our earlier time leading up to today—and what I believe a team of fellow employees, sharing core values, have done to ensure our continued success. I came to the County Engineering Department in 1978 and often thought it would be great to “have my own business”…I was naive and eager but smart enough to wait out the recession of the early ‘80’s. Plus, I really enjoyed working as the Office Engineer for the County and stayed more than 6 years getting to know people, places and establishing relationships. In my County role, I learned a ton about our agencies and infrastructure and this helped define what quality meant to me. Many of the projects that I reviewed needed help and I believed that I (we) could do better. So with my wife Cindy’s blessing, in July 1984 I took the plunge and opened an office in our living room. Very quickly, Mr. Craig Campbell heard about this endeavor and we decided to join forces. I recognized Craig as the engineer I wasn’t so we became a great team. As our business intent became known, projects miraculously came in the door. Some of the first were John DeVincenzo’s Avila Barn along with the Varian Ranch, then the Bluffs in Pismo Beach and the County’s AASP’s Master Drainage Plan. Agency work became a specialty market as well. During our 30 years we have acted as the Department of Public Works for Atascadero, Pismo Beach and Arroyo Grande. Managing various special districts occupied much of my time so Craig and the expanding staff worked on the growing number of private and public works projects. We came to recognize the synergy of having a surveying component and created an alliance with the best land surveyor in the County, (maybe the State) Tom Mastin. Tom and his staff shared space with us from the beginning and eventually we merged our companies. Then along came Brad Brechwald. Brad was a refugee from another local engineering company and he wanted more variety. I think that he has been “overwhelmed” with variety ever since. Establishing a viable succession plan had been one of my goals for the last 10 years and as CEO Brad now oversees the overall aspects of our firm. Tom Zehnder is now our outstanding COO and he also came with some unique talents. Whoever thought we would be doing refinery work as mechanical engineers?! Jorge Aguilar is our newest Principal and also brought a unique skill: transportation engineering. (I still can’t even spell it…but Jorge knows what to do!) One of the best decisions of my early business life was to chase Rob Miller down the hall to hire him. He was walking out the door after being told we didn’t need any new staff at the time!
