The top healthcare architecture firms in the US

The Top Healthcare Architecture Firms in the US of 2026

5 September 2026

At e-architect, we track the firms shaping the built environment, from major civic and commercial projects to highly specialized healthcare facilities. As healthcare providers respond to outpatient growth, workforce pressures, new technologies, changing service lines, and higher expectations for patient experience, the role of healthcare architects continues to expand.

For a healthcare executive or facilities leader, an architecture firm is also a long-term business partner. Healthcare architecture in 2026 is not simply about creating attractive buildings. The strongest healthcare design firms help providers think through patient experience, clinical workflows, staff wellbeing, technology integration, operational performance, outpatient expansion, sustainability, and adaptability.

Between March and June 2026, we researched more than 30 leading healthcare architecture firms in the United States. We evaluated and rank-ordered the top six using the following weighted criteria:

• Integrated Service Model (25%): Architecture, Engineering, Interior Design, and Planning under one roof.
• Healthcare Portfolio Depth (22%): Typology range and verified project volume.
• Industry Recognition (18%): National rankings and peer-reviewed awards.
• Evidence-Based Design Credentials (18%): EDAC certifications, published research.
• National Footprint (10%): Number of verified studio locations.
• Healthcare Specialization Depth (7%): Concentration of firm revenue in healthcare.

BSA, for Integrated Healthcare Architecture, Engineering, Interior Design, and Planning

BSA is an integrated, multidisciplinary design firm with 8 studios across the United States, pairing local leadership with national resources. The firm delivers architecture, engineering, interior design, and planning under one roof for healthcare, education, and research environments, backed by an integrated delivery model, an evidence-based design approach, and a Modern Healthcare Top 8 ranking.

BSA has operated since 1975 and has built a reputation as a partner for healthcare clients who want all four disciplines coordinated under a single project team. Its 8 studios combine local market knowledge with national resources, so project teams can serve clients across multiple regions while keeping that same integrated structure intact.

• Location: Indianapolis, IN, with 8 studios across the United States
• Year Founded: 1975

• Industry Recognition: Modern Healthcare Top 8

Gresham Smith, for Hospital Renovation and Campus Transformation

Gresham Smith is a Nashville-based architecture and engineering firm that has specialized in healthcare design for more than 50 years, with particular strength in hospital renovation, acute care campus transformation, and occupied-facility upgrades. The firm integrates licensed architects and engineers in unified project teams, managing structural, mechanical, and electrical coordination under a single delivery structure. With multiple offices across the United States, Gresham Smith brings both regional expertise and the engineering depth technically complex healthcare construction requires.

Ranked #12 in Building Design+Construction’s 2025 Giants 400 Healthcare list with $80 million in healthcare facility revenue, Gresham Smith has a sustained national presence in the sector. Its portfolio spans acute care hospitals, ambulatory clinics, behavioral health facilities, and advanced care environments across multiple regions. The firm’s strength in occupied renovation work, phasing complex construction within active hospital settings to protect clinical continuity, is a recognized operational differentiator. Planning services are less centrally embedded in its delivery model than in full A/E/I/P firms.

• Location: Nashville, TN (HQ) with multiple U.S. offices
• Year Founded: 1967
• Services Offered: Architecture, Engineering, Interior Design

HMC Architects, for Community and Regional Hospital Design

HMC Architects is a California-based firm founded in 1940, with decades of experience designing acute care hospitals, medical office buildings, community health centers, and ambulatory facilities. The firm provides architecture, planning, and interior design with an emphasis on human-centered, evidence-based environments that serve diverse regional populations. HMC’s strongest domain is community hospital design, where operational efficiency, patient experience, and community identity drive every planning decision.

HMC ranked #15 in Modern Healthcare’s 2025 Construction and Design Survey, confirming its consistent national standing in healthcare design. Following the 2025 acquisition of Bassetti Architects, HMC extended its geographic reach into the Pacific Northwest, adding healthcare and higher education projects in that region to its California base. HMC does not provide in-house mechanical, electrical, or plumbing engineering; clients needing integrated MEP coordination must engage separate consultants, an extra coordination layer in project delivery.

• Location: Ontario, CA (HQ) with offices in Southern California, Northern California, and Pacific Northwest
• Year Founded: 1940
• Services Offered: Architecture, Planning, Interior Design

Array Architects, for Ambulatory and Outpatient Facility Design

Array Architects is a healthcare-only firm based in the Philadelphia area, with more than 40 years of practice focused exclusively on ambulatory care, medical office buildings, community health centers, and clinical space programming. Working solely in healthcare gives Array a precise operational vocabulary for outpatient building types: patient flow efficiency, infection control in non-hospital settings, and flexibility to accommodate rapidly shifting care delivery models. The firm’s boutique-to-midsize scale keeps senior leadership closely involved on every project.

Ranked #16 in Building Design+Construction’s 2025 Giants 400 Healthcare list with $48.4 million in healthcare facility revenue, Array has a high concentration of ambulatory healthcare work for a firm of its size. Its Cooper University Health Care Moorestown Ambulatory Care Facility earned three separate design awards and is among the most referenced adaptive reuse healthcare case studies in recent years. Array does not provide in-house engineering, MEP, or comprehensive planning services, which limits scope for clients who need integrated structural, mechanical, or master planning coordination from a single entity.

Location: Philadelphia area, PA (multiple U.S. offices)

Year Founded: 1983

Services Offered: Architecture, Interior Design, Space Programming

BWBR, for Behavioral and Mental Health Facility Design

BWBR is a Saint Paul, Minnesota-based firm with more than 100 years of practice in architecture, interior design, and planning, with a deep specialization in behavioral and mental health facility design. The firm serves psychiatric hospitals, community mental health centers, inpatient behavioral health units, and integrated care environments where behavioral health and primary care overlap. BWBR’s proprietary BWBR+ performance services add post-occupancy evaluation and data-driven design accountability beyond standard project delivery.

With more than 175 employees across offices in Saint Paul, Madison, and Omaha, BWBR brings Upper Midwest depth and a national behavioral health portfolio to complex programming challenges. Its published research on behavioral health cost-return relationships has established it as a contributor to the mental health design conversation. BWBR’s services do not include in-house mechanical, electrical, or plumbing engineering; larger integrated projects require external MEP consultants.

Location: Saint Paul, MN (with offices in Madison, WI and Omaha, NE)

Year Founded: 1922

Services Offered: Architecture, Interior Design, Planning

Corgan, for Behavioral Health and Ambulatory Clinic Design

Corgan is a large Dallas-based architecture and interior design firm founded in 1938, with 22 offices worldwide and more than 1,200 employees. Within its broad multi-sector portfolio, Corgan’s healthcare practice focuses on behavioral health facilities, ambulatory clinics, medical office buildings, and specialty care environments. The firm publishes data-driven healthcare design research, including its “Better Hospitals. Better Design” research series, and its healthcare team applies analytical methods to evidence-based programming decisions.

Healthcare is a secondary market for Corgan alongside aviation, data centers, and commercial workplace, reflected in its $8.8 million in healthcare-specific revenue in BD+C’s 2025 Giants 400 Healthcare report. Corgan does not provide in-house mechanical, electrical, or plumbing engineering services; all MEP coordination for healthcare projects runs through external consultant relationships. Clients who want a single firm to deliver architecture, engineering, interior design, and planning under one contractual structure will need to engage multiple parties when working with Corgan on technically integrated healthcare facilities.
