Jeff Sizemore - Owner

The Dog House Doggie Daycare and Dog Boarding Facility is owned by Jeff Sizemore. Jeff has been running the business for 14 years and he lives on site. Prior to buying the business in the summer of 2000, Jeff owned a pet sitting service, but realized that for what he was charging clients to spend 1 hour with their dog, he could take care of a dog all day for the same price -- and the dogs wouldn’t have to be alone most of the day.

Jeff is a stickler for cleanliness and is proud that The Dog House is the cleanest kennel facility he’s ever seen. He is committed to providing the best possible doggy daycare and dog boarding experience for his four-legged guests and their owners. He feels that the best way to do that is have the dogs out of their kennels and active most of the day, playing, running socializing.

His top priority is the welfare of the dogs in his care. To that end, he hires only the best possible employees who provide loving attention, close supervision for all play, and deliver a personal and hands-on doggie day care and dog boarding experience.

His open door policy (anyone can stop by at any time) is unique in the industry, but as he says, “We’re an open book and never have anything to hide.”

If you would like to talk to Jeff or have any questions, please feel free to call 303-781-4577 and ask to speak to him, or you can email Jeff directly at

Madison - Staff - The Dog HouseMaddie - Supervisor AM

Maddie applied to The Dog House because she loved dogs and loved the idea of working with them. She thought that The Dog House would be a great start to working with dogs. In her first week of work she was excited to be greeted by all the dogs and was super happy to find out that her coworkers were welcoming and happy she was there. She moved quickly into a supervisor position within her first few months of working for showing her commitment to the dogs and their happiness. She then moved into the Lead AM Supervisor position when she showed her true commitment in the mornings for making sure everything was all set for the evenings. She is also the assistant groomer and co owns Happy Bubbles Grooming with Emily. She continues to make new relationships with the dogs as well as her coworkers and customers. Maddie also enjoys reading and spending time alone with her dog Lola outside in the fresh air. You can find Maddie working in the mornings, always ready to help with whatever you and your pup may need!

Emily - Staff - The Dog HouseEmily - Groomer

Emily started working for The Dog House the summer of 2016 and what she found was not only a job but a career. She was coming to The Dog House for a change of atmosphere. She didn’t like working with people so much. She worked her way through being a kennel tech, and then became a supervisor for showing her passion for her job and the dogs. She has gotten better at working with people as well! Now she leads the evenings as Lead PM Supervisor. She makes sure that the customers are happy as well as making sure that the facility is nice and clean for the next day. Although sometimes being the lead can be stressful sometimes, she gets through it with a smile on her face knowing everyone is happy. She has recently started her grooming business at The Dog House with Maddie called Happy Bubbles. She discovered her passion while working here. So she went and got her grooming certificate. Emily is a youth pastor outside of work. She also plays the drums, guitar, and sings in the band at her church. She takes her dog Rosie to the lake to swim as well. You will find Emily in the evenings as well as the weekends with a smile on her face.

Tessa - Staff - The Dog HouseTessa - Evening Supervisor

Tessa came to The Dog House with already some experience with working with dogs. Before she came here, she was walking dogs. She wanted to further her employment and decided to apply here for a kennel tech position. When she came, she loved the fact that she could learn so much! She has learned so much about the types of dog breeds and their behaviors. She even loves it here so much that one day she wants to open her own doggy daycare. Whenever there is miscommunication, Tessa is always trying to figure things out and get them sorted. That’s why she was promoted quickly to the evening supervisor. She showed great work ethic and she now loves interacting both with the dogs and their parents. Tessa keeps herself busy outside of work by playing golf and tennis, as well as hiking. She has a few furry kids as well; Dobby and Oliver. Tessa continues to make the customers happy at the end of the night by putting a smile on their faces.

Ashley - Staff - The Dog HouseAshley - Morning Supervisor

Ashley applied to The Dog House looking to work with dogs. She found out quickly that she loved making relationships with the dogs and her fellow coworkers. She loves the atmosphere that she came into. As most of the staff here, she found out that she works better with dogs. She avoids drama between people, so she keeps herself surrounded by the dogs most of the time. Ashley quickly moved from kennel tech to the morning supervisor because she showed Jeff that she is always on task and cares deeply for the dogs and their safety. Ashley wants to, one day, run a shelter for battered and unwanted animals. As a mommy of two wonderful boys and two puggles, she keeps herself busy outside of work as well. She likes spending time with her kids, going to concerts, and hanging out with her friends.

Jordyn - Staff - The Dog HouseJordyn - Weekend Supervisor

Jordyn came to The Dog House looking for a change. She worked with people in customer service but she wanted to see what it was like working with digs, and what she came to find out was that she absolutely loved it. She became close with so many of the dogs. She loves coming to work to get to know all the different personalities of all the dogs and meeting new dogs as they come in. Even though she has to change the poop buckets, Jordyn still comes in knowing that she gets to spend time with all the dogs. She gained her supervisor position when she showed strong leadership and patience with the dogs. One day she hopes to train dogs to become certified therapy dogs. Jordyn like music when it comes to her hobbies outside of work. She enjoys singing, and she even taught herself the piano and ukulele!
