Professional Supporter and "The Wife" Cassie Ahrens

Cassie Ahrens is the backbone of TreeLine CrossFit. She has been married to Coach Justin for seven years, but has been by his side for eleven years. She herself is a very talented athlete. She has played all sports growing up, but continued to play Softball and Volleyball on scholarship in college. She currently is an elementary school teacher in Halsey, Oregon and has a way with kiddos that we all wish we had. She takes great pride in the self-confidence CrossFit has provided her and the things she has achieved because of it. Cassie makes a mean guacamole and is a strong believer in the fact that “Taco Tuesday” shouldn’t only be on Tuesday. She also would much rather watch Monday Night Football than almost anything else. 

What is your favorite healthy meal and cheat meal?

  • My favorite healthy meal is: Grilled Chicken, Avacado, Steamed Broccoli, Sweet Potato, Quinoa Brown Rice, Garlic and Goat Cheese.
  • My favorite cheat meal is...I have many.  A bowl(s) of Honey Bunches of Oats (the blue box), a big fatty burger and sweet potato fries, or a major cheat would be an Olive Garden date with Kaylee for soup, pasta, and tons of breadsticks.

What advice do you have for new members at TreeLine
My advice to new members is to never take yourself too seriously, find a workout buddy, and never go 2 weeks without doing squats.
Having fun is such a great, important part of working out and being healthy! We want TreeLine to be a place you WANT to come to, and we love to have fun, so don't be afraid to be silly with us!
Have not only a gym, class, or coach to hold you accountable, but having someone you can text when you need some motivation, make sure they're going to make it to class that day, or to make fun of yourself when you can't sit down properly on the toilet, workout buddies are great! Don't have one yet? Pick me!
Lastly, see above about not spacing your squats out too much. Nobody likes being stuck on the toilet.

Gym Mascot Griffey aka Griff

Griffey is our one and a half year old GoldenDoodle. He is still a pup. He is super friendly and loves everyone. Although he is super mouthy, we can assure you it is not an attempt to bite. He is simply showing his love by putting your wrist in his mouth. If you sit next to him, he is sure to lay in your lap and will make it difficult to get up and leave him. He loves to go on walks and/or runs, so no need to even ask about taking him for a walk...just do it. Although he may pull a little, don't let him. Feel free to bring him treats, we don't mind!  Show him all the love you want...HE DOESN'T SHED!
