Who We Are

We provide mental health services, counseling, and psychological testing for all ages, addressing a wide range of issues and concerns. NPPA is extremely proud of the years of experience, community respect, and level of excellence each clinician brings to the practice. Our psychologists, counselors, and social workers all hold independent licenses. NPPA has been established and serving Aberdeen, South Dakota and the surrounding communities since 1991. 

How We Can Help

We offer both in-office and telehealth services. You may choose self-pay or we accept multiple private insurances, SD Medicaid and Medicare, as well as numerous EAPs. Please call with any questions about fee arrangements. We are glad to discuss your options. 

What We Do

Our focus is to help you heal and grow from your struggles, find balance, and move forward and pursue your potential. We provide a confidential, safe, and supportive space. We will be there for you every step of your journey, listening to your concerns, and customizing a personalized treatment plan with you. 

What To Expect

Upon contacting NPPA, our staff will discuss your requests with you, and set up an appointment with a clinician that best matches your areas of concern. Your questions will be answered to include fees for services and any quotes on your estimated benefits, if using insurance. You will fill out our intake paperwork, either through our online client portal that will be emailed to you or in person, if requested. 

At your first appointment, your clinician will discuss confidentiality of treatment and other information and practice policies. Your clinician will also fully discuss your areas of concern, the services they offer, and you will collaboratively develop a treatment plan to meet your goals. Recommendations and possible referrals, if appropriate, will be discussed. We will support you and encourage you towards your goals!
