Karen Wentworth
Controller/Director of Human Resources

In my roles as controller and human resources director, I oversee the accounting, customer service and human resources teams.  I joined the company back in 2000 coming from a manufacturing and accounting background at Nabisco Foods and Tyco Plastics.  As a team, we take pride in the fact that when you call, the phone will be answered by a knowledgeable staff member who can help you.  If we don’t  know the answer to the question asked, we will either find out or direct you to the team member who does. 

Along with my husband Ken, I am committed to our local community and school district.  We both volunteer our time and talents and sponsor many community groups, teams and organizations.  I serve on the Board of Directors for the Lakeville Chamber Foundation and mentor 8th grade girls in a program called Hope for Tomorrow.  I am the proud mother of two beautiful adult daughters and grandmother to an adorable French Bulldog named Stitch!  I am a sports fanatic especially for the Minnesota Wild, love to travel and read in my spare time.

Dana Turner
HR Generalist/Customer Service

I started with ChemQuest in July of 2019. In my role as the Human Resources Specialist, my main responsibility is to take care of our company’s greatest asset, our employees. You may also hear my voice at the other end of the phone when I back up our customer service department, making sure our customers and vendors get the best service possible. I enjoy giving back to the communities of Lakeville and Farmington, where I have lived and worked for the last 20 plus years. My family, including my 2 grown children and son in law are the center of my personal life, so spending time with them and traveling when I can, are what I do in my free time.

Karen Amell
Customer Service

I joined the ChemQuest Team in September 2019.  While still quite the “newbie”, I already love, love, love the daily variety: answering phones, taking orders/order entry and donning the hat of Junior Sleuth, tracking down mysteries!  When not impersonating Sherlock Holmes, I am at home in Burnsville, with my husband, Greg.  We have two grown sons, Nick and Paul.  Some of my favorite pastimes include:  stained glass painting, piano, long hikes and volunteering with Greg in the 3M Visiting Wizard program.  I look forward to working with everyone!
