For Medical Providers | Chronic Illness & ADHD Referrals

Collaborative, trauma-informed psychotherapy and psychological testing for adults navigating chronic illness, anxiety, trauma, and complex medical concerns.

I provide depth-oriented psychotherapy to clients throughout Illinois or a PSYPACT-participating state, and in-person comprehensive neuropsychological evaluations in Chicago. My clinical focus is the intersection of mental health and medical complexity, including chronic disease, anxiety, and ADHD. I work closely with referring providers to ensure coordinated, whole-person care.

When to Refer

Referrals are appropriate for adults (18+) experiencing:

Chronic health conditions or complex medical needs, including autoimmune, inflammatory, post-viral, endocrine, gastrointestinal, environmentally linked illnesses (e.g., mold illness or MCS), and pain-related concerns
Anxiety, panic, or persistent health-related stress, including illness anxiety or medical-procedure stress
Functional somatic symptoms or ADHD
Stress-related or trauma concerns, including complex PTSD or dissociation
Grief, burnout, or identity-related life transitions
Mood or emotional concerns (e.g., depression, adjustment stress)

I am especially experienced with patients whose psychological symptoms are entangled with their medical picture, where standard therapy referrals may not have been a good fit in the past. I am comfortable reviewing medical records, understanding the psychological impact of diagnoses and treatments, and working with medically complex presentations rather than around them.

Collaborative Care

I work from the belief that mental and physical health are deeply interconnected. Many clients navigating chronic illness and medical complexity do best when their providers are communicating with each other.

In practice, coordination with referring providers typically includes:

Confirming receipt of the referral and closing the loop on whether the client engaged
Sharing brief clinical updates or coordination notes at meaningful treatment milestones (with written client consent)
Aligning on treatment priorities so that psychological care complements medical treatment rather than operating separately
Connecting through secure messaging, brief phone calls, or shared documentation, depending on what works best for your workflow

For testing referrals, the referring provider receives a copy of the full written evaluation report (with client consent), including diagnostic impressions, clinical recommendations, and any suggested follow-up. If you have specific referral questions you would like addressed in the evaluation, those can be incorporated into the assessment.

My integrative approach draws on somatic, relational, and depth-oriented modalities, including ACT, and trauma-focused interventions. The focus is always on supporting your patient’s capacity for self-regulation, engagement with their medical care, and overall quality of life.

You can expect clear communication, respect for your clinical role, and a genuine focus on the client’s autonomy and wellbeing.

Frequently Asked Questions

Once I receive a referral, I reach out directly to the client to schedule a brief consultation or intake. If they decide to move forward, we typically begin care within 1 to 2 weeks. I also confirm receipt with the referring provider (with client consent) to ensure a clear handoff.

If the client does not respond to outreach, I follow up once more after 7 to 10 days. If there is still no response, the referral is considered closed. Referring providers can request updates at any point.

For therapy clients, brief clinical summaries or coordination notes can be provided with the client’s written authorization. These typically include presenting concerns, focus of treatment, relevant progress updates, and coordination recommendations.

For testing clients, a detailed written evaluation report is a standard part of the assessment process and is shared with the referring provider (with client consent). This includes diagnostic impressions, recommendations, and relevant clinical context.

I do not provide forensic evaluations, FMLA or disability determinations, or legal documentation. If a client requires these services, I can refer them to appropriate specialists.

My practice focuses on outpatient psychotherapy and psychological testing for adults. Lumara is not a crisis stabilization or higher-level-of-care setting. Clients needing more intensive support, such as IOP, PHP, inpatient stabilization, or medical-legal evaluations, would be better served by other programs. I also do not provide acute emergency support, medication management, or primary care services.

I provide comprehensive psychological and neuropsychological evaluations for adults, covering ADHD, executive functioning, cognitive concerns, learning differences, and complex diagnostic clarification. Evaluations include a clinical interview, standardized testing, a detailed written report with diagnostic impressions and recommendations, and a feedback session. Turnaround for the written report is typically 2 to 3 weeks after testing is complete.

If you have specific referral questions or diagnostic concerns you would like addressed, those can be incorporated into the evaluation design. Testing referrals can be submitted through the secure referral form above.
