About us

Our Story

Emily Karhoff serves as the Director of Operations – BCBA and is one of the original founders of MonArk ABA. She grew up in Northwest Ohio graduating from Ottawa-Glandorf High School. She went on to Bowling Green State University where she received her Bachelors of Science in Early Childhood Education with a Special Education minor in May 2009. Emily has worked in the field of Applied Behavior Analysis (ABA) since January 2011 in multiple settings. She worked in Fort Wayne, Indiana in a clinical setting for almost 5 years where she gained most of her hands-on experience and knowledge in ABA. During this time, she earned her Board Certified Assistant Behavior Analyst (BCaBA) certification from coursework completed through Florida Institute of Technology.


Emily’s passion is always to get quality ABA to as many clients as possible. Knowing the need in Ohio, Emily returned to Northwest Ohio to work in a school setting in the summer of 2017. There she was able to create an ABA program within a public school overseeing 18+ RBTs and assisting approximately 80+ students in her program age preschool through 8th grade. In 2019, she completed her Masters of Arts in Applied Behavior Analysis with an Autism Studies certificate at Ball State University and passed her boards to become a Board Certified Behavior Analyst (BCBA).


In Emily’s role at MonArk ABA Therapy, she is passionate about building the organization and team to scale and being the catalyst to delivering quality ABA services to even MORE individuals. The goal of MonArk ABA is to get the best quality ABA to as many individuals who will be enriched by the value of ABA.


Emily and her husband Brad reside in Findlay, Ohio with their two sons Hunter and Mason, and pups Luna & Buck. Emily enjoys spending time with her boys and traveling when she is not at MonArk helping incredible humans grow and become the best version of themselves.

Albert and Kristen Closson’s MonArk story started with their daughter Izzy. The Clossons wanted to relocate back to the Putnam County area, but not having access to ABA for Izzy was a deal breaker. Izzy had received ABA care for years in Dallas, Texas, which was extremely transformational for her. The Clossons knew that the NW Ohio area had almost no ABA care, so they were determined to start independently with no ABA background. As they started forming the company, they quickly met The Karhoffs and The Quinns and knew it was a dream ownership team. As they brought everyone together, they took more of a behind-the-scenes role as the expertise of Emily, Kyle, and Sheiletha can drive the best quality of care and growth for the children and families in NW Ohio. Albert’s role in renovating the centers and Kristen’s role in parent advocacy is where they want to support the MonArk families and enable Izzy and all of her buddies to get the care they need to live their best lives.

Sheiletha Quinn has over 24 years of Healthcare experience working for companies such as Astra Zenca and GE Healthcare. She began in the field of ABA and Autism intervention in 2013 and has a vast history of work with various physicians as well as other medical professionals to raise awareness as well as coordinate services for families. Her extensive experience allows her to best assist you in the inquiry and enrollment process. Her expertise and passion for ABA have led her in helping many families connect to ABA services over the years. In fact, her young adult brother in law has severe Autism and benefited greatly from ABA therapy services provided when he was younger and through his teen years. She looks forward to connecting with you to see how Monark ABA can assist you and your child’s needs. 

Our Social Mission

Drowning is the #1 cause of death for children with Autism in the United States. Therefore, we donate a portion of our profits each year to 2 different organizations who provide free swim safety lessons to children with autism and other developmental disabilities. We believe that together we can reach higher to accomplish the best outcomes and help save the lives of those affected with Autism and other developmental disabilities.


Additionally, we strive to purchase as many of our supplies and equipment from charitable organizations that help people with disabilities, such as, Goodwill and the Salvation Army. On account of our focus to purchase with these organizations, we provide thousands of dollars in revenue that they are able to use for employment, health, and other benefits to members of our community. Together we can reach higher to connect the pieces for those whom we serve, as well as, others that these organizations serve.
