About Dobias Professional Engineering, PLLC

Welcome to Dobias Professional Engineering, where expertise, precision, and innovation converge to create exceptional mechanical and plumbing engineering solutions.

Who We Are

At DPE, we strive to be pioneers in delivering the industry’s best mechanical and plumbing solutions, offering exceptional customer service and expertly engineered designs. With a strong commitment to excellence, we aim to set the standard for engineered designs, implementation, maintenance, and upgrades for mechanical and plumbing systems. 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 revolves around a commitment to:

  • Client-Centric Service: By placing our clients at the forefront, we prioritize clear communication, extensive collaboration, and personalized solutions to ensure every project aligns with both client and project-specific needs.
  • 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.

Areas of Expertise

At DPE, we specialize in:

  • Hospital and healthcare design: From Trauma level Level 1 hospitals to medical office buildings, DPE has the experience and expertise to provide anything needed for your healthcare project. Our CEO is one of only four mechanical engineers in the State of Oklahoma to be a ASHRAE certified Healthcare Facility Design Professional (HFDP).
  • Heavy industrial design: With years of experience in industrial design across various sectors—manufacturing, water/wastewater, aviation, and more—we specialize in environments that are highly corrosive, explosive, or require strict cleanliness.
  • Commercial restaurants: While many firms can provide commercial restaurant designs, few understand the complexities of airflow, building pressure, and latent heat load challenges. At DPE, we go beyond traditional designs by addressing not only the building’s air handling units, but also the hood, make-up air units, and ANSUL systems, ensuring a comprehensive and efficient solution.
  • 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

Our commitment is persistent and embraces:

  • Quality Assurance: Ensuring the highest quality standards are met throughout every phase of the project, from conceptualization to implementation and beyond.
  • Continual Improvement: Striving for ongoing learning and improvement, we stay educated on the latest technological advancements and industry best practices to deliver cutting-edge solutions.
  • Client Satisfaction: Placing utmost importance on client satisfaction, we endeavor to build long-term relationships by consistently exceeding expectations. Unforeseeable conditions and mistakes from all parties happen from time-to-time, but at DPE, when problems do arise, we are committed to solving the issue to everyone’s satisfaction. If there is an issue, we will fix it.
