Aviation HMMH has addressed and resolved environmental noise and air quality problems in airspace sectors, airports, heliports, and military bases throughout the United States and around the world. Our federal clients include the Federal Aviation Administration (FAA), the Navy, the Air Force, the Department of Justice, and the National Park Service. We also provide solutions to airport proprietors and industries in the private sector such as airlines and aircraft manufacturers. Our work has earned us an international reputation for technical excellence and for expertise and insight into regulations and review processes. We are equally renowned for our ability to communicate effectively with the public.
I have worked with HMMH for about thirty years. Their capability to work effectively with airports, adversarial community groups, and other governmental entities is of significant value to us. I would enthusiastically recommend HMMH.
