Seth Simmons

With over 30 years in construction, Seth has owned and operated several companies, including Southwest Design Building for over 10 years and Southwest Facility Maintenance.

He brings leadership for staff and operations, as well as direction for all design-build operations, program management, project management, condition assessment services and construction processes to Sigma Southwest. He possesses a unique understanding of design, authority and city review processes many contractors don’t have because of the years previously spent with a design-build firm, as well as the necessary construction processes and administration.

In his spare time, Seth can be found restoring old trucks, and participates in and occasionally hosts ‘ratrod’ events region-wide.

Gino brings over 25 years of experience and expertise in the construction industry to Sigma Southwest. Starting his career in the residential arena he soon moved into the commercial market, in particular the hospital market working for a variety of companies as project manager and construction manager. He then became a Sr. Project Manager/Estimator for multifamily projects, completing over a dozen pre-construction projects and then awarded the completion of many of those projects. He subsequently moved into the operations side while helping with project management to the various project teams in the field.

With Gino’s field and operations experience, he knows what it takes to make a successful team focused on the needs and satisfaction of the client. Overall, his main goal is to ensure that clients receive the highest-quality services that successfully fulfill their needs as well as meet and exceed their expectations.

In his spare time, Gino enjoys spending time with his wife and two daughters and enjoying all that life offers.

Bill Santoro possesses more than 30 years of construction experience in his role as Chief Estimator.

He has worked in various capacities including Field Supervision, Project Management and Estimating. Prior to joining the Sigma team Bill was owner of a concrete company.

Bill has applied this experience to his years at Sigma in both Project Management and Estimating. With his breadth of experience and various roles within the industry, Bill has a comprehensive understanding of the needs and intents of Sigma clients.

Bill possesses a great work ethic and diligence when reviewing documents uncovering any missing information or details, conflicts between the drawings and specifications, or any needed clarifications. He has a strong reputation for being fair and honest with subcontractors, which often leads to preferred pricing from that industry.

Bill was born in Sacramento, California, then moved numerous times as the child of a father in the military.

He is active with the American Society of Certified Professional Estimators. He received Bachelor of Science and Bachelor of Arts degrees from the University of Nebraska. He also has completed numerous courses at the Construction Estimating Institute.

When he’s not reviewing documents, Bill enjoys traveling and taking part in family activities. Bill is also a numismatist, which means he collects coins.

The professional accomplishment of which he is most proud is when projects come in under budget and ahead of schedule.

The best business advice he has been given: “Before starting a construction project, always have a solid understanding of the client’s expectations.”

The best business advice Bill has to share: “The understanding that if you see any issue or problem on a project, know that the client will see it as well.”

That’s the voice of experience talking.

Juan Carlos is extremely proud of his family and the children he has raised, the life he has been able to afford them, and the education and degrees he has attained. When meeting people they quickly see that he is not a person to hide anything about himself, he is a very authentic and peaceful person.

The best business advice he has been given has interestingly been about Japanese business philosophies – their companies are considered as their baby that they must feed (invest in) until maturity. This feed/investment is not only in material assets but also in the training of its HR to make it sustainable.

The best business advice he will share is that all processes can be improved. This follows the Japanese philosophy of continuous improvement.

Jennifer Kirby, Business Administrator

Jennifer Kirby was born in Lancaster, CA but has lived in Arizona most of her life. With her ABA and upcoming SHRM certification, Jennifer has overseen the office management, HR and accounting and contract management for Southwest Design Building and now Sigma Southwest for over eight years.

With a ‘can-do’ attitude and the ability to rapidly master and implement new methods and procedures, Jennifer has been able to help create processes to successfully coordinate and manage successful operations flow for a growing operation.

Jennifer considers her children as her best personal accomplishments, never forgetting the most important priorities in life. People might be surprised to learn that she used to race dirt track cars in her young teens.

The best business advice Jennifer’s received was from an (almost) famous man (Seth Simmons) who said to her “Just Trust Me” and so far it’s all been good!

The best business advice she would share with others is “when you fall down just pick yourself up again”.
