Our Mission

The mission of the Clark Community Mental Health Center is “Moving Forward, Improving Lives and Communities, through Compassionate Care.”

About Our Site

Clark Community Mental Health Center, a nonprofit Certified Community Behavioral Health Organization, offers comprehensive outpatient mental health services to residents of Southwest Missouri’s Barry, Lawrence, and Dade counties. With a focus on underserved and rural populations, Clark Center provides outpatient therapy, school-based therapy, psychological assessment, psychiatric medication management, substance use treatment, crisis support, and case management for all ages. Our dedicated interdisciplinary team, comprised of psychologists, counselors, social workers, nurses, nurse practitioners, psychiatrists, and other behavioral health staff members, ensures high quality integrated care.

Clark Center’s mission, “Moving Forward, Improving Lives and Communities Through Compassionate Care,” underpins our commitment to inclusive services for all clients, regardless of financial ability to pay for services. We strive for individualized care to enhance wellness, combat stigma, and raise mental health awareness within our communities.

Clark Center’s internship program boasts strengths in comprehensive supervision and a breadth of clinical opportunities. Each intern is assigned a primary supervisor and multiple secondary supervisors, with each supervisor bringing unique strengths and perspectives to the learning experience. Interns receive at least four hours of supervision weekly, through a combination of individual and group formats. The internship year also exposes interns to a variety of training experiences, including therapy with a diverse clientele, psychological testing, crisis intervention, substance use treatment, community education/outreach, and exposure to evidence-based practices such as PCIT and EMDR.

Clark Center’s office environment is known for its comfortable, collaborative, and collegial atmosphere. Interns are valued as peers, fostering a balanced blend of professionalism and camaraderie. Join us for an enriching internship experience and embark on a transformative journey together.

Training Opportunities

The Clark Center experience allows interns to provide individual and/or group treatment to individuals struggling with a wide array of behavioral health disorders. As would be expected in an outpatient, community mental health setting, individuals most often present with SUD, depression, and anxiety, but it is not uncommon for interns to be exposed to individuals presenting with psychotic features, severe co-occurring disorders, and personality disorders.

If the intern expresses interest in any particular cultural group (i.e. impoverished, Hmong, Karen, Hispanic, gay or lesbian, physical disability, faith-based) referrals are directed to that intern.

Rotation Schedule

The Clark Center is flexible when it comes to scheduling activities of interns and providers. Normal operating hours are Monday through Friday from 8:00 am – 5:00 pm. The intern will be assigned opportunities to complete clinical interviews for assessment and be scheduled for individual and group counseling sessions. The intern can also expect to be able to observe providers perform EBPs like EMDR and PCIT. Interns will have scheduled supervision meetings but can expect to communicate with the supervisor between meetings as needed.

Placement Locations

Clark Center has outpatient counseling offices in Monett, Cassville, Greenfield and Aurora and provides counseling services in 10 school districts within the three county catchment area. Interns will have an office in the Monett office and can expect to spend one-two days each week in one of the adjacent schools.

Supervised Experiences

Supervision is taken very seriously. Time will be scheduled to ensure supervision is provided on a consistent, timely basis. Interns can expect to receive the minimum number of the hours of supervision as stipulated by NPTC. Supervision is a two-way street, a collaborative relationship between individuals who learn from each other.  Being prepared to ask questions, express concerns, sharing of successes, reviewing cases, discussing theories, address ethical elements of providing counseling, and other issues relevant to counseling are all potential “grist”  for the supervision “mill”. Supervision is not therapy. But, individual issues and personal concerns that may impact the delivery of counseling services are also important elements of supervision. Interns are encouraged to be assertive, to be invested in the process, and to expect the supervisor to be responsible and responsive colleagues who are part of a team. 

Patient Populations




The area for which the Clark Center serves as a CCBHC consists of three rural counties in southwest Missouri. The population of the largest community in the three county area is approximately 9,000 residents. The population of one of the counties served is essentially the same as that of the largest town in our service area, making it very rural with a great deal of open farmland. With fewer than 85,000 individuals living in a three county area, population density is very low.

The median household income in the three counties is approximately $40,000 per year with nearly 20% of the population living in poverty. Even in the largest community in the three counties where there is a relatively high percentage of white-collar jobs, over 60% of school students receive free or reduced lunches. Even though there are many families struggling with low incomes, the rate of street homelessness is very low; this is attributed to friends and families being willing to house individuals.

Due to serving a largely low-income area, the Clark Center has not and will not turn away individuals with moderate to severe needs based upon an inability to pay. All regardless of socio-economic status who enter through our Open Access model for screening receive a free screening; no pay source is billed for the service. In order to meet the needs of those who have inability to pay, we attempt to utilize the services of interns and we are an NHSC site where professionals can benefit from loan repayment if they work at a facility that utilizes an approved sliding fee scale.

The area largely consists of white residents with approximately 90% of the population being white. With that being said, there is a growing Hispanic community in two of the counties. In those counties, it is not uncommon for 30% of the students in the school classroom to have Hispanic ethnicity and it is estimated that approximately 7% of those older than five years old speak a language other than English in the home. Though a relatively small number from this community are seeking services, the agency hires at present three bilingual staff to assist individuals who might have a language barrier which would otherwise prevent treatment.

Life in Monett, MO

Monett is far from a typical rural town. Instead of being a bedroom community to a larger city, it is the home of many businesses. Monett, whose motto is Pride and Progress, is the home of many flourishing companies. Monett is the home base of Jack Henry and Associates, a computer banking software company, that employees 1000 people in Monett alone. While other communities were closing small hospitals, Cox Monett opened a new hospital in 2020. Though no commercial flights are available to and from Monett, due to business activity, Monett has the sixth busiest airport in Missouri.

Monett is busy during the day and has many fast food and authentic Mexican restaurant options. One need only to travel an hour to experience nightlife activities in Springfield or Joplin or just a little over an hour to enjoy the many Branson, MO activities. Monett is the ideal location for those who like outdoor activities like hiking, fishing, boating or hunting as two lakes and Roaring River State Park are all just an hour away.

Policy on Marijuana Use


This policy provides guidelines to navigate the rules established by Missouri Amendment 3 regarding both medical and recreational use of marijuana.


Definitions related to this policy include:

Marijuana – Cannabis Indica, Cannabis sativa, and Cannabis ruderalis, hybrids of such species, and any other strains commonly understood within the scientific community to constitute marijuana, as well as resin from the marijuana plant and marijuana infused products.

Marijuana infused products – Products that are infused, dipped, coated, sprayed, or mixed with marijuana or an extract thereof and are intended for use or consumption other than by smoking.

Medical marijuana – Use by a qualifying patient for a qualifying medical condition as indicated by the individual holding a valid medical marijuana identification card.

Recreational marijuana – Covers all marijuana use not associated for medical purposes as indicated by having a valid medical marijuana use card.

Marijuana intoxication – Symptoms following use of marijuana that include decrease in short-term memory, dry mouth, impaired perception and motor skills, red eyes, sleepiness, mild euphoria.  Even if physical symptoms are not present, one will be considered intoxicated if any amount of marijuana was smoked/ingested for the past 8 hours.

Qualifying Medical Condition –The condition of, symptoms related to or side-effects from the treatment of:

  1. Cancer;
  2. Epilepsy;
  3. Glaucoma;
  4. Intractable migraines unresponsive to other treatment;
  5. A chronic medical condition that causes severe, persistent pain or persistent muscle spasms, including but not limited to those with multiple sclerosis, seizures, Parkinson’s Disease, and Tourette’s syndrome;

  7. Human immunodeficiency or acquired immune deficiency syndrome;
  8.

Qualifying patient – An individual diagnosed with at least one qualifying medical condition.

Bona fide occupational qualification – Requirement of person’s employment for which marijuana use would create a conflict i.e. staff who occasionally need to be available after hours on an unscheduled basis, staff who transport clients before and after regular work hours


(a) The Clark Center maintains a zero-tolerance policy against recreational marijuana use.  Staff and applicants testing positive for marijuana who have no valid medical card have no protection from hiring/firing decisions under Missouri Amendment 3.  Staff found to have used marijuana recreationally by means of random or targeted testing will be terminated, and applicants without a valid medical card who test positive for marijuana will not be considered for employment. 

(b) The Clark Center does not discriminate in hiring/firing decisions or in matters of conditions of employment against staff and applicants who have a “qualifying medical condition” and who use marijuana for medical purposes and who have a medical card or return a positive test.  Employees must produce a valid medical marijuana card and attest that they have a qualifying medical condition.  However, as allowed by the Amendment 3, Clark does not make accommodation for this medical use when and where such accommodations are not required.  

Below is a list of scenarios whereby a medical marijuana card-holder is not protected against hiring and firing decisions or in matters of employment conditions:

  1. Failure or unwillingness to produce a valid card and attest to a qualifying medical condition.
  2. Job requirements conflict with a bona fide occupational qualification.
  3. Use affects the safety of others 
  4. Use affects the person’s ability to perform job-related activities. 
  5. Medical card holders who while working are intoxicated as defined by marijuana intoxication.
  6. Medical card holders who use during work hours or who have marijuana on Clark property are not protected by the anti-discrimination clause.

In the above unprotected circumstances, an individual with a medical marijuana card becomes subject to Clark’s zero-tolerance policy.
