When it comes to keeping young professionals happy, San Antonio is doing a bang-up job. A new report released by Fortune magazine and Great Place to Work finds two San Antonio companies, and a total of 11 Texas companies, among the top 100 Best Workplaces for Millennials 2018.

Familiar insurance/financial service company USAA (United Services Automobile Association) comes in at No. 40, while San Antonio energy company NuStar Energy L.P. appears at No. 69.

More than 434,000 survey respondents from Great Place to Work-Certified companies provided input into this annual list. The study analyzed how millennials rated their organizations on more than 50 different metrics defining great workplaces, such as managers' competence, respect and fairness in the workplace, opportunities for meaningful work, executive leadership, and opportunities to innovate and contribute to the organization’s success.

The report also analyzed an index of factors where millennials often lag behind other workers, such as access to meaningful work, fair pay, and plans for a future with their organizations. Companies were evaluated as to whether they were creating great workplaces for all millennials — regardless of who they are or what they do for the organization.

Surveys were anonymous, and companies needed to employ at least 50 millennials to be considered. Employees rated the companies on challenges, atmosphere, rewards, pride, communication, and bosses with a numerical ranking. Here's what makes the San Antonio companies shine:

USAA, where 91 percent of employees say their workplace is great, places an emphasis on employee health. Employees enjoy an onsite clinic and pharmacy, a fitness center, massage and physical therapy facilities, plus healthy rewards initiatives. Workers also benefit from aggressive retirement and bonus programs.

At NuStar Energy, 93 percent of employees say their workplace is great. Employees engage in numerous summer and holiday activities — leaders often host impromptu workplace barbecues and family days. Incentive and savings programs are also highlighted, as are financial grants for employees in difficult personal hardships.

In Texas, Houston-based David Weekley Homes leads the list at No. 19. Dallas companies Ryan, Inc. (No. 44) and Prime Lending (No. 58) are next, followed by Austin's WP Engine, Inc. (No. 61) and Dallas' Encompass Home Health (No. 66).

Abilene makes an appearance with Funeral Directors Life Insurance Company at No. 92, followed by Houston’s Camden Property Trust at No. 94 and Houston's Hilcorp Energy Company at No. 95. Rounding out the Texas representation is Arlington’s Texas Health Resources, Inc. at No. 96.
