-“Brian Sielaff and his team at Tamarack Grove Engineering came through for us twice when we needed affordable, custom-design engineering while under pressure of time because of approaching winter conditions. Their response has been fast and personable and they seem always willing to go the extra mile.”

-“I have known Brian and hired Tamarack Grove Engineering numerous times over the course of the last five years as the key structural engineer of my design team at Supervalu.  Brian was a team player and a valued adviser throughout the entire design and construction process.  He is diligent and efficient in completing drawings, reports, meeting schedule deadlines and coordinating with other team members.  Additionally, his thoughtful and quick communication skills are truly valued beyond my expectation.  Brian understands and accomplishes all aspects of business with a high degree of professionalism.

I would recommend Tamarack Grove Engineering for any of your structural engineering need.  Our relationship began as a working relationship and has grown into a strong friendship.  He possesses the many attributes required, in my opinion, to succeed in life as well as in business endeavors.  Brian’s integrity, work ethic, communication skills and efficiency make Tamarack Grove Engineering a great asset to any team.”
