Roger C. Rinn, PhD

Licensed Psychologist

Beginning in 1971, I have practiced Clinical Psychology in Huntsville, Alabama. I began my professional career at the Huntsville-Madison County Mental Health Center and entered full time private practice in 1978. I have experience evaluating and treating a wide variety of patients including those suffering from anxiety, depression, relationship and behavioral disorders. Moreover, I see parents about their children and teens with underachievement, AD/HD and Oppositional Defiant Disorder. If you have any questions regarding your unique issues, please call my staff at anytime.
I conduct psychological evaluations with testing and psychotherapy using cognitive behavior therapy and behavior modification as my major tactics of intervention. I also work with couples and individuals to enhance relationships. I assist patients in career choice and planning.

Nikki Heidelbach, PsyD

Licensed Psychologist

I have worked in the mental health field for more than 10 years. I received my PsyD from Spalding University in Louisville, KY. 


Through training and work, I've had the opportunity to be in a variety of settings, which has helped develop an understanding of how the same symptoms or problems can impact people very differently. Understanding and respecting your situation is my goal, and we will work together to set your personal treatment goals.

I am comfortable treating symptoms related to depression, anxiety, PTSD, military separations, and relationship problems. I also work with families to increase coping skills related to ADHD and other behavior concerns.

In addition to therapy, I can also conduct a variety of psychological and psychoeducational assessments, including evaluation for ADHD and Learning Disabilities.
