Mountain Research Joins ARRO Consulting

We are excited to share that, effective June 30, 2026, Mountain Research, LLC has joined ARRO Consulting, Inc. (ARRO).

For more than 40 years, we’ve had the privilege of serving clients throughout Central Pennsylvania and the Mid-Atlantic region. Since 1985, our technical expertise, dependable service, and commitment to lasting client relationships have been the foundation of our environmental consulting and drilling services.

Joining ARRO marks an exciting new chapter in our story while building on the values that have guided our firm from the very beginning. As part of the ARRO family, we will benefit from expanded resources, multidisciplinary expertise, and a broader geographic presence—strengthening our ability to serve our clients while continuing to provide the responsive, high-quality service that has always been the cornerstone of our business.

Our drilling services will continue operation as a dedicated affiliate of ARRO, preserving the technical excellence and trusted relationships that have defined Mountain Research for decades.

“Mountain Research is an excellent fit for ARRO,” said Ihsan Al-Fayyomi, President and CEO of ARRO Consulting. “Our organizations share a commitment to technical excellence, practical solutions, and strong client relationships. We also share a culture that values our people and collaboration. By bringing our teams together, we are expanding the services we provide while continuing to deliver the personalized service and expertise our clients value.”

While this partnership expands the resources and capabilities available to those we serve, one thing remains unchanged: our commitment to our clients, our people, and the communities we serve. We are incredibly grateful for the trust you’ve placed in us over the years, and we’re excited to begin this next chapter as part of the ARRO family.
