Getting Started

  • Pax Mentis Psychiatry offers comprehensive psychiatric evaluations and ongoing care for adults, adolescents, and children ages 4 and up. Areas of focus include perinatal mental health, child and adolescent psychiatry, attention and executive-functioning concerns, mood and anxiety disorders, integrative psychiatry, and second-opinion consultations.

    Clinical services in Texas are provided through Pax Mentis Psychiatry, PLLC. Clinical services in California are provided directly by Dr. Niiang Mung.

  • No. Pax Mentis Psychiatry is a cash-based practice. This structure optimizes patient privacy, allows for more flexible and non-traditional appointment windows, and supports treatment planning driven by clinical needs and patient values rather than insurance requirements. As a self-pay practice, Pax Mentis Psychiatry does not bill directly to insurance. Superbills may be provided upon request for potential patient-initiated out-of-network reimbursement. 

    Pax Mentis Psychiatry does not complete insurance prior authorizations or communicate with insurance companies regarding coverage determinations.


  • Payments are processed securely through Spruce Health. Accepted payment methods include credit and debit cards, ACH bank transfers, and Zelle.

    HSA and FSA cards are accepted. Eligibility and reimbursement are determined by your individual plan. We can provide a receipt or superbill upon request. Patients are responsible for submitting documentation to their HSA, FSA, or insurance plan.


  • Payment is required 48 hours prior to your scheduled appointment. This confirms your appointment time and allows for appropriate clinical and administrative preparation.


  • You can begin by selecting “Request an Appointment” or submitting a request through the secure Contact form. Intake forms will be provided through a HIPAA-compliant system prior to your first appointment.

Appointments & Care

  • The initial evaluation is a comprehensive assessment that explores symptoms and history, as well as your values, strengths, priorities, and areas of concern. In addition to detailed clinical history-taking, laboratory testing may be recommended when clinically appropriate to better understand contributing medical factors.

    Depending on the complexity of the case, diagnostic clarification and treatment planning may occur during the initial evaluation or extend into one to two follow-up visits. For children and adolescents, caregiver input and developmentally appropriate assessment are included.

  • Yes. Medications may be recommended when clinically appropriate and are always discussed through shared decision-making. Treatment may also include lifestyle guidance, behavioral strategies, psychoeducation, and faith-informed considerations if desired.


  • Controlled substances (such as stimulant medications) may be prescribed when clinically indicated, following a thorough evaluation and in accordance with federal and state regulations. Ongoing monitoring and follow-up are required. Certain controlled substances may not be prescribed via telehealth depending on regulatory requirements.  

    Pax Mentis Psychiatry emphasizes evidence-based, safety-focused prescribing and does not routinely initiate certain high-risk medications. Some medications may be continued, adjusted, or tapered when clinically appropriate, including medications that were prescribed prior to establishing care.


  • Appointments may include brief therapeutic interventions, psychoeducation, and supportive guidance. Pax Mentis Psychiatry does not offer weekly or long-term psychotherapy. Many patients choose to work with a separate therapist while receiving psychiatric care.

Logistics & Policies

  • Yes. All services are provided via secure, HIPAA-compliant telepsychiatry. Patients must be physically located in Texas or California at the time of their appointment.

  • No. Due to licensing regulations, patients must be located in Texas or California during their appointment.
