About Us

About Cornerstone Healthcare Consulting

Guiding physicians and practices toward growth, independence, and sustainable success.

Work With Us

Your Vision. Our Commitment.

Welcome to Cornerstone Healthcare Consulting & Management—where your vision becomes our mission. As advocates for independent and physician-led care, we believe that the backbone of a thriving healthcare system lies in empowered providers. Whether you’re launching your first private practice, revitalizing an established one, or growing with purpose, we’re by your side—bringing practical strategy, heartfelt partnership, and faith‑inspired dedication. At Cornerstone, we don’t just consult—we walk alongside you, bridging the gap between your passion for medicine and a sustainable, flourishing practice.

Our Values

Integrity

We believe trust is the foundation of every successful practice. Our guidance is transparent, ethical, and always centered on your best interests.

Innnovation

Healthcare is evolving, and so are we. We bring creative solutions that help practices stay agile, efficient, and patient-focused.

Excellence

From the first consultation to the launch of your practice, we bring professionalism, attention to detail, and a commitment to delivering the highest standards.

Who We Serve

Medical Practice Startups

We guide physicians and entrepreneurs through every step of opening a new medical practice—from location selection to credentialing—so you can launch with confidence.

Established Medical Practices

For practices facing operational, financial, or staffing challenges, we provide proven strategies to streamline systems, improve efficiency, and restore profitability.

Independent Physicians

We support providers seeking freedom from corporate healthcare by helping them design sustainable, patient-centered practices that reflect their values.

Our Process

Step 1: Discover

We begin by listening. Through an in-depth consultation, we learn about your goals, challenges, and vision for your practice.

Step 2: Design

Next, we create a customized roadmap—covering operations, compliance, staffing, and financial planning—so you have a clear path forward.

Step 3: Implement

We coordinate vendors, systems, and resources while guiding you step-by-step through execution to ensure nothing is overlooked.

Step 4: Support

Our relationship doesn’t have to end at launch. We provide ongoing support, management solutions, and strategic guidance to help your practice thrive.
