Houston is a global city with strengths in business, international trade, entertainment, culture, media, fashion, science, sports, technology, education, medicine and research. Nicknamed the “Space City,” Houston is home to NASA's Johnson Space Center, where the Mission Control Center is located. It also houses the Texas Medical Center—the world's largest concentration of healthcare and research institutions. However, the city is most well-known for its strength in the oil and natural gas industry. Allegis Partners proudly serves Houston and the state of Texas, placing top professionals and executives into leading roles within organizations across this broad range of industries.
