Dr. Phil Hirsch is a national leader in Integrated Behavioral Health (IBH) for primary care, known for helping rural and small-system clinics implement Integrated Behavioral Health programs that are evidence-based, true to the validated research model, and that use smart, data-driven staffing algorithms. By adding BH specialists in a financially sustainable way, clinics realize substantial new net revenue per primary care practitioner each month. As Founder and Chief Executive of Third Rail Integrations, he supports primary care practices in transforming the way behavioral health needs are identified and delivered - with emphases on access, quality and coordination of care.
Dr. Hirsch’s commitment to improving behavioral healthcare began early. As a child, he regularly accompanied his father to a state psychiatric hospital where a family member lived for many years. The visits were meant to bring moments of connection—music, snacks, and human presence—but what struck him most was the stagnation of the environment. Patients rarely seemed to improve, and the system itself felt heavy and immobile. Even as a young boy, he found himself thinking, there has to be a better way.
During adolescence, he experienced firsthand the importance of supportive, relational care. At a difficult time at home and in school, he met periodically with a junior high counselor who was not clinically trained but was fully present—listening carefully, offering steady encouragement, and helping Phil navigate daily challenges. It left a lasting impression: human connection, even delivered intermittently and without formal treatment protocols, could be life-changing. This insight would later shape his belief that team-based, relationship-centered care is essential in modern primary care.
After completing his doctoral training, Dr. Hirsch became increasingly focused on healthcare delivery systems. He was struck by research showing that in a typical primary care setting, fewer than 40% of patients with behavioral health needs were ever identified, much less connected to helpful services. The data reinforced the same thought he had since childhood: there has to be a better way. It also pushed him to look beyond individual treatment and toward system-level solutions that could improve patient outcomes.
Early in his career, Dr. Hirsch was introduced to the emerging field of telebehavioral health. Excited by its potential to expand access—especially in rural communities—he arranged a lunch meeting with a psychiatrist who served as medical director for a major healthcare organization. Throughout their conversation, every time Dr. Hirsch focused on telebehavioral health, the discussion shifted toward integrated care; and when he shifted toward integrated care, it returned to telebehavioral health. When he finally asked why, the medical director offered an insight that would stay with him for decades: “Think medium and message. The message is integrated care. The medium that makes it possible is telepsychiatry.”
That framing shaped the arc of Dr. Hirsch’s career. His early clinical experience helped him understand the realities of patient pathways and the fragmentation many families face. His work in telebehavioral health highlighted the possibilities of modern technology. But it was the integrated-care perspective—coordinated, team-based, embedded within primary care—that ultimately aligned with his deepest professional commitments.
More than twenty years later, Third Rail Integrations represents the convergence of those experiences. The company’s mission is simple: to help primary care clinics deliver effective, sustainable behavioral health support as part of everyday care. Dr. Hirsch’s model is practical and accessible, designed especially for rural and small-system clinics that historically have struggled to offer behavioral health services despite high community need.
Dr. Hirsch’s leadership is grounded in the belief that integrated care is not only achievable but essential. Primary care clinicians see patients where they live, work, and seek help first. By equipping those clinicians with the tools, workflows, and revenue models needed to support behavioral health, Third Rail Integrations helps clinics improve outcomes while strengthening financial stability.
Today, Dr. Hirsch’s work reflects decades of learning, observation, and commitment to improving how care is delivered. From early childhood exposure to institutional systems, to formative relationships in adolescence, to research-driven insights in adulthood, his career has been shaped by a consistent belief: people deserve better pathways to behavioral health support, and primary care clinics are uniquely positioned to deliver it.
Dr. Hirsch continues to work with clinics across the country to build sustainable behavioral health integration programs that improve access, reduce clinician burden, and create meaningful patient outcomes—helping primary care become the true front line of mental health care. Launching in January, 2026, Third Rail Integrations is available to any interested clinic or medical group almost anywhere in the U.S.

A Practical Guide to Sustainable Behavioral
Health Integration in Primary Care
By Philip A. Hirsch, PhD (Phil Hirsch, PhD)
Founder & CEO, Third Rail Integrations, LLC
Introduction
Primary Care is the front line for Behavioral Health in the United States. For millions of patients—especially in rural and small-system clinics—Primary Care is the only point of contact for mental health concerns. Yet most clinics lack the staffing capacity, financial structure, or operational guidance to integrate Behavioral Health in a way that is sustainable.
This guide outlines a practical, revenue-positive model for Behavioral Health integration that fits the realities of Primary Care today. It reflects more than 25 years of experience in integrated care, Behavioral Health program development, and collaboration between Primary Care providers and Behavioral Health specialists.
1. Why Behavioral Health Integration Matters
Behavioral Health concerns are among the most common issues raised in Primary Care, including:
• Depression
• Anxiety
• Stress and adjustment concerns
• Substance-use risk
• Social isolation
• Chronic illness–related distress
Integrated Behavioral Health improves access, coordination, outcomes, and clinician satisfaction—and a well-designed model can become a revenue-positive service line for Primary Care practices.
2. Challenges in Rural and Small-System Clinics
Rural clinics face predictable barriers: limited staff, financial constraints, overwhelmed PCPs, and access issues. Integration must be designed for real-world conditions, using existing resources whenever possible.
3. A Practical, Revenue-Positive Model
Key principles include:
• Integration must fit Primary Care workflow.
• The model must be financially sustainable.
• PCPs must feel supported, not burdened.
• Behavioral Health specialists must be part of the team.
• Rural clinics require tailored approaches.
4. Common Barriers and How to Avoid Them
Barrier: “We can’t afford to hire anyone.
”Solution: Proper staffing algorithms can make this a substantial revenue-positive service line for Primary Care practices.
Barrier: "Won't this increase PCP workload.”
Solution: Good workflows reduce PCP burden and improve coordination.
Barrier: “We tried integration before and it failed.”
Solution: Vendor-driven models often fail; practical, clinic-owned models succeed.
5. Steps to Launching an Integrated Behavioral Health Program
1. Assess clinic readiness.
2. Choose the right model.
3. Establish roles and workflows.
4. Implement warm handoffs.
5. Train staff and begin small.
6. Track outcomes and financials.
7. Expand intentionally.
A Note from our Founder & CEO
Behavioral Health integration is not a new concept—its introduction in healthcare literature dates back more than 20 years. Yet among the estimated 294,000 Primary Care practices in the U.S., only about 7% report having suitable access to integrated Behavioral Health services.We designed and built Third Rail Integrations, LLC with these realities in mind. Your Integrated Behavioral Health services must be timely, coordinated, and sustainable. With the right workflows and structure, integration becomes both achievable and financially reliable.
Let us show you how your clinic can build a sustainable, revenue-positive Behavioral Health service line—without creating operational burden.

Integrated Behavioral Health: The Stages of Building a Sustainable Model
by Phil Hirsch, PhD - Founder & CEO
Third Rail Integrations, LLC
Integrated behavioral health has become essential in primary care. Rising demand, limited specialty access, and pressure on primary care teams have made behavioral health support a core part of medical care. Most clinics do not build integrated care all at once. Instead, they move through stages, learning as they go and strengthening their systems over time.
This framework outlines the stages many clinics experience on the path to a sustainable integrated behavioral health model.
Stage 1: Referral-Based Workflows
Most clinics begin with referral-based workflows.
A patient screens positive for depression, anxiety, trauma, or substance use, and the provider refers them to an outside behavioral health clinician.
This approach is familiar, but often fragile:
- Long wait lists
- Limited communication with external providers
- High drop-off rates
- No shared treatment planning
- PCPs feeling responsible without visibility into the patient’s care
Referral-based care is an important starting point, but rarely meets the full behavioral health needs of a clinic’s population.
Stage 2: On-Site or Adjacent Behavioral Health
To improve access, many clinics hire or contract a behavioral health clinician. This often brings meaningful benefits, including brief interventions and improved communication.
- However, new challenges can emerge:
- Specialists quickly reach capacity
- Appointment backlogs grow
- Clinic space becomes limited
- Workflows may remain unclear
- Measurement practices are inconsistent
- Reimbursement opportunities may be missed
Adding a behavioral health clinician is helpful but does not, by itself, create an integrated care model.
Stage 3: Telebehavioral Health as a Force Multiplier
Many clinics now strengthen access through telebehavioral health.
This approach expands capacity without increasing the demand on clinic space or staffing.
Telebehavioral health can:
- reduce pressure on physical office space
- provide flexible scheduling for patients
- support rural and underserved communities
- align with coordinated warm handoff workflows
- allow specialists to participate in team-based care remotely
When integrated into clinic operations, telebehavioral health stabilizes access and reduces strain on both PCPs and behavioral health clinicians.
Stage 4: Team-Based Integrated Care
Team-based integrated care represents a shift from individual efforts to a coordinated system.
In this stage, primary care providers, behavioral health clinicians, and care managers work together using shared goals and routine communication.
Key elements include:
- consistent use of screening and measurement tools
- shared treatment plans
- stepped-care pathways for adjusting treatment
- regular case review meetings
- defined processes for suicide risk and care transitions
- Patients experience their care as coordinated rather than fragmented.
Clinics begin to see appropriate reimbursement for behavioral health services delivered within primary care.
Stage 5: Sustainable Integrated Care
Sustainable integrated care is built on consistency and clear workflows.
A sustainable model does not require perfection. It requires steady, reliable processes that hold up over time.
Clinics in this stage typically:
- maintain workflows that continue through staffing changes
- use data to guide clinical decisions
- balance behavioral health capacity with patient needs
- reliably capture reimbursement
- see improvements in patient outcomes
- report lower burnout among PCPs and improved clinic culture
Integrated care becomes part of how the clinic defines itself.
Moving Forward
Every clinic begins integrated behavioral health from a different point. The important factor is not where a clinic starts, but how it develops over time. Integrated behavioral health grows in stages—steadily, thoughtfully, and with attention to the needs of patients, providers, and communities.
Sustainable integrated care emerges through small, intentional steps that strengthen access, coordination, and long-term patient wellbeing.
