John Hartenburg


A little about John:
He loves making sure Knot & Rope customers have an excellent shopping experience by helping them select the right product at a great price.

Personal Hobbies/Interests:
When John's not working hard in the office or shop, you can find him working on his climbing skills, practicing his splicing or going for a run around town. As you can probably imagine, he enjoys tree climbing and personally testing all of the arborist ropes Knot & Rope Supply carries. When he says that he is running for lunch, he literally means that he's going for a run and that is his lunch.

What kind of music does John like?Great question. He is a big fan of mid 80's rock. Another fact about John is that he loves to shred the frets on his electric guitar.

Brinda Calkins

Customer Service & Accounts Receivable

A little about Brinda:
Brinda joined our team back in 2014 and has a long background in Customer Service. When you call in or email us here at Knot & Rope Supply, it’s a good chance it will be Brinda you deal with. She wants to make sure all our customers, walk away feeling like they received the best customer service, making Knot & Rope Supply stand out from the rest! Brinda also is in charge of the Accounts Receivable at Knot & Rope Supply, just another way she gets to work one on one with our customers.

Brinda is probably one of the most selective in the office when it comes to music. She grooves to the 80's, 90's and country music. As she puts it, "music you can understand."

Ryan Underwood

Shop Manager

A little about Ryan:
Ryan joined our team late 2012 and has since been roped into a few different roles in our warehouse. He has proven to be a star at shipping, stocking, maintenance and 3-strand splicing. Oh, we can't forget the 3-strand whipping either. There's no telling what's next for Ryan as there is always something new for him to learn and excel at.

Personal Hobbies/Interests:
When Ryan isn't busting out some hard core manila splices, you can find him tearing up the streets on his motorcycle. He has a passion for anything with an engine and at least two wheels. Ryan also loves to hunt and play/watch all kinds of sports.

What kind of music does Ryan like?
There's nothing like entering the shop and wondering what kind of music will be playing on the radio. Ryan's choice of music is "good ol' country", rock and Celtic music.

Tom loves to go hunting and fishing whenever he can. When he's not in the woods or baiting a hook, you can catch him watching the Detroit Tigers or The Fighting Irish of Notre Dame.

If it were up to Tom, there would be some rock, metal or classical music playing all day long in the shop.
