Sandra Tangedal – Partner / Office Manager

Sandra Tangedal is married to Alton Tangedal and has been his business partner since ATAL’s inception in 1996. At that time, she worked for the federal government. After twenty years of employment as a public servant, she needed a career change and in 2001 she became ATAL’s accountant and has worked there ever since.

“As an owner in the business, I think what I enjoy the most is watching the growth of our staff members. Seeing them enter our firm as shy, tentative individuals, and in a relatively short period of time, taking on large projects and handling them very well. To me, that shows that we are providing a good environment for growth and learning.”

Sandra graduated in 1985 with a Diploma in Accounting from the Saskatchewan Institute of Applied Science and Technology. Much of her free time is dedicated to family activities: her two children are active in sports and school functions, and she often hosts family get-togethers at her home. Sandra enjoys reading and being part of a book club, and is quite proud of her trombone skills.

Florian Lazar – Intern Architect

Born and educated in southern Romania, Florian brings a unique perspective to the ATAL team. His European and Middle Eastern experience in urban planning, architecture and interior design bring fresh ideas to each of his projects.  As a child he watched as villages transformed into cities seemingly overnight. Playing in buildings as they were being constructed, he began to imagine the final product, as well as to dream that one day he too would be able to build such structures.

Florian appreciates that although the architectural process is the same for each project, it is ultimately good teamwork which guarantees both an exciting final result and a pleased client.

In addition to his work at ATAL, Florian participates in international industrial and graphic design competitions, and is daily inspired by his wife and two children.

Between renovating her yard and looking after her children, there isn’t much time left for hobbies, but here and there she manages to fit in cross country skiing and running.






Liam Clarke – Intermediate Architectural Technologist

Liam’s father is a carpenter, but a couple of winters swinging a hammer at construction sites was enough to convince him that drafting might be a better – and warmer – way to be involved in the building process. He graduated from the Saskatchewan Institute of Applied Science and Technology with a diploma in Architectural and Building Technologies in 2009, and joined ATAL in the same year. An active athlete, Liam plays recreational hockey, golf and curling and is a fan of all sorts of football, including the Green and White. He still practices carpentry these days, but only on his own renovation projects.





Shawn Coates – Intermediate Architectural Technologist

He is a 2009 graduate of the Saskatchewan Institute of Applied Science and Technology with a diploma in Architectural and Building Technologies. In the same year, he joined the ATAL team. He spends his spare time on various hobbies, down at the archery range and relaxing with friends and family.

From there an industry connection led him to ATAL in August 2010. In his spare time, Duane plays a variety of sports, and also exercises his musical muscles on the guitar.
