Our Story

The beginning

Croyle-Nielsen Therapeutic Associates, Inc. builds on a long history of excellence started by Dr. Grant Croyle, a renowned and respected clinician, who founded our Johnstown practice in 1989 when he started Croyle Psychological Associates.

Through hard work and uncompromising dedication to providing quality psychological services, Dr. Croyle was able to grow the practice and over the years it gained a reputation as one of the very best providers of behavioral health services in the Laurel Highlands.

Continued growth

Since 2013, the company has grown significantly and continues to grow. A second location was added in Somerset in February 2014, and a number of new services were launched, including behavior support and trauma informed therapeutic solutions and training services. We continue to grow the company by offering new services and expanded locations, and are excited about what our future holds.

According to CEO and Co-Owner Jesper P. Nielsen, a large part of the growth is due to an uncompromising dedication to quality, the recruitment of top notch clinicians and employees, and a servant leadership style, which brings all team members into decisions regarding the values and direction of the company.

A new owner and a new name

After a brief period of ownership by one of Dr. Croyle’s former clinicians, Carole Serbin, the practice returned to Croyle family ownership in 2013, when Dr. Croyle’s niece, Amy M. (Croyle) Nielsen, a distinguished and respected Behavior Support Specialist in her own right, purchased the Johnstown practice with her husband Jesper P. Nielsen. Amy and Jesper have long been passionate about improving the lives and circumstances of others and therefore the acquisition of the practice founded by Dr. Croyle was a natural fit.

A new name was chosen to reflect the continued involvement of the Croyle family and adherence to the values that Dr. Croyle had established, while signaling an expansion of the scope of the services offered and that a new company with a more expansive vision had emerged. The name became Croyle-Nielsen Therapeutic Associates, Inc.
