About Dobias Professional Engineering, PLLC
Welcome to Dobias Professional Engineering where we specialize in mechanical and plumbing engineering, with a focus on thoughtful design, practical solutions, and dependable results. Every system is approached with a clear understanding of its requirements, constraints, and long-term performance.
Who We Are
At DPE, we’re committed to delivering reliable mechanical and plumbing solutions backed by strong engineering and responsive service. Our designs prioritize long-term performance, ease of maintenance, and constructability. Whether it’s a new system or an upgrade, we bring a consistent focus on quality, coordination, and cost control.
Our commitment to delivering coordinated projects that are both on-budget and on-time is what sets us apart from other engineering firms.
Our Approach
Our philosophy is built on three core principles:
- Client-Centered Service: We prioritize clear communication and practical solutions to ensure every design reflects the specific goals of the client and the unique needs of the project.
- Technical Excellence: Drawing on extensive knowledge and expertise to design, develop, and implement mechanical and plumbing solutions that exceed industry standards and client expectations.
- Innovation and Sustainability: By embracing innovation and sustainable practices, we strive to create forward-thinking designs that not only meet project requirements but also contribute to a greener, more sustainable future.
- Strong Local Contractor Partnerships: We maintain strong relationships with a wide range of local contractors, which plays a key role in supporting coordination, constructability, and a smooth build-out process. These partnerships make the construction phase more efficient and help ensure our designs move clearly from concept to installation. Our projects are developed to be buildable, not just lines on paper.
Areas of Expertise
At DPE, we specialize in:
- Hospital and healthcare design: DPE supports projects from Level 1 trauma centers to medical office buildings. Our CEO is one of only four mechanical engineers in Oklahoma with ASHRAE’s Healthcare Facility Design Professional (HFDP) certification. We deliver mechanical and plumbing solutions that meet healthcare standards.
- Heavy industrial design: We have extensive experience in manufacturing, water/wastewater, aviation, and more. Our designs address corrosive materials, explosive conditions, and strict cleanliness requirements.
- Commercial restaurants: Restaurant design involves complex airflow, building pressure, and heat load challenges. We provide coordinated solutions for air handling units, exhaust hoods, make-up air systems, and ANSUL fire suppression.
- Remodels: With nearly 15 years of commercial building remodeling experience, DPE understands the complexities and challenges of a remodel. We know that it’s not just about designing a functional space, but also how the remodel affects the pressures, airflow, and plumbing of the surrounding areas.
- Other areas of expertise: DPE also has extensive experience in a wide range of projects, including natatoriums, laboratories with Phoenix Valve systems and controls, dental and orthodontic surgery offices, large-scale assisted living facilities, museums, auditoriums and gyms, pool pump houses, general office spaces, K-12 schools, higher education institutions, apartments, shopping plazas, gas stations, and car washes.

Our commitment is persistent and embraces:
- Quality Assurance: We ensure the highest standards throughout every phase—from concept to completion and beyond.
- Continual Improvement: We stay current with the latest technology and industry best practices to provide innovative, effective solutions.
