Meet Our Team – Oklahoma

Brian Hopper

Partner, Executive Operations Manager


As husbands and fathers go, Brian is first-rate.  He has been married to his high school sweetheart, Stephanie, for 23 years now.  Their children are Caleb, 17, Claire, 15, and Patrick, 12.  Charlie is the family’s canine member.  Hanging out with this crew is Brian’s favorite activity. He and Stephanie both grew up in the Oklahoma City area and are surrounded here with friends and extended family.  Brian’s first job as a kid was mowing yards with his brothers.  If the yard had a pool, and its owners furthermore allowed the boys to plunge in at their labor’s end, the owners got a discount. 

Brian’s love for the hometown people and its quality of life has led to volunteerism.  He serves on the United Way of Norman finance council, teaches 4th graders on Sunday at his church, and is a church elder.  He also cheers for the local university, Oklahoma, which is his alma mater.  His NFL loyalty lies farther afield with the Buffalo Bills.

Rob Crowe 

Account Manager (Oklahoma City)


Rob and his wife, Jamie, have a big, lively crew of kids and animals, starting with their eight sons—Caleb, Andre, Jordan, Zachery, Steven, Nate, James, and Christian.  Four dogs, two cats, two donkeys, a pig and 6 hens mean there are animals enough to go around, and then some.

Rob still finds time to pursue his interests.  He collects, builds, and restores cars, and just about anything else that is motorized.  Happily, despite his love of speed, he doesn’t race his cars; he saves that for his jet skis!  Football is another love.  He began playing the game when he was only four.  As a kid growing up in OKC, he naturally became devoted to the Sooners, and dreamed that one day, he’d play in the NFL.  More specifically, he dreamed of being Brian Bosworth, playing in the NFL.

Rob believes in the value of volunteering, and is teaching it to his kids.  The whole family  regularly pitches in with Rotary Council and Chamber community projects.  This aligns perfectly with one of Ron’s “bucket list” goals, which is to play a role in bettering his city.

Educational & Professional Credentials:

  • BA from Oklahoma University

Luis Sosa 

Account Manager (Oklahoma City)



Luis Sosa’s coming-to-America story is inspiring and sometimes frightening. For 17 years, he knew success as a physician in his native Cuba, even serving as chief of a large medical group. But he did not know freedom; and so he searched, discreetly, for a way to reachAmerica. This led him to apply to Cuba’s overseas medical missions program. He was thoroughly vetted—to assure he wasn’t considering defection—and then sent to a repressive nation in South America. The authorities took his passport.

Luis, however, prayed, as he frequently does.The passport was returned. He immediately began a difficult journey to the nation’s capital (with itsAmerican Embassy), assuming he’d be in the U.S.within days. Instead, the embassy required stacks of paperwork. He was told that in about six months, he’d learn if he’d been accepted. At this point—with Luis dead broke in a country where he knew no one—help began pouring in from unexpected quarters. Only a month later, the US government flew him to the States.Through a maze of circumstances, Luis was led to a church family and finally to work with LUSA. He is open to what God is teaching him and has embraced the landscape industry with the enthusiasm of a life-long learner. He says that the credit for all that is good in his life belongs to God in Jesus Christ’s name.

Bill Turner

Business Developer


Bill possesses and nurtures a zest for life.  He reads fiction and history, climbs 14ers in Colorado (32 to date), rescues dogs, and even gave skydiving a try.   (Once was enough, thank you very much).  He plays tennis and chess, roots for the OKC Thunder and the Dallas Cowboys, and loves music, photography, his three dogs, and his wife.  (Not, of course, in that order.)

He is fond of Oklahoma.  Its people, he says, are the friendliest he’s ever known.  (Did I mention that he grew up in Austin?)  The thing he finds most rewarding in his work is establishing relationships with clients and earning their trust.

As you might expect, Bill has a varied bucket list.  It includes sailing the Greek Isles, visiting Salzburg, Austria, joining the crowd at a Super Bowl and at the World Series, and climbing another 14er.  Viva la vida!
