Long-time Rio Grande Valley volleyball coach Dolores Olguin-Trevino is unassuming as she paces back and forth across the Alice High School gym floor.

Wearing black jogging pants and a matching black T-shirt and a red fanny pack, she’s easily lost in the group of volleyball girls.

However, her wealth of knowledge about the game and her expertise are obvious in just a few moments around her. That’s why when she spoke or even offered the smallest bit of advice at the South Texas Spiker’s Camp, every girl in the Alice gym listened.

The one-time head volleyball coach at Brownsville Hanna High School and Los Fresnos assistant is leading the four-day Alice volleyball skills camp. Some 63 girls ranging from incoming seventh graders to varsity are signed up for the camp, which runs until Thursday.

Alice coach Cynthia Wareham said she Olguin-Trevino is the best coach she knows to run the camp leading up to the start of volleyball practice on Aug. 1.

Olguin-Trevino’s resume includes a long run at Hanna, which were coached Wareham between 1992 and 1996. She retired and returned to coach as an assistant at Los Fresnos. She is currently the volleyball coach at St. Joseph Academy in Brownsville and runs the South Texas Spikers, a traveling club volleyball team. Her teams have won numerous district titles and made a handful of appearances in the Region IV volleyball tournament.

The camp included a handful of setting and hitting drills. There were also some team building exercises. Wareham said in the mix is also an effort to learn a new defense which she says help Alice against some of its taller opposition this season.

“The camp will help hone their setting, hitting, serving, blocking and defensive skills,” Wareham said. “It will also teach them a new defense which we will utilize against big hitting teams since we lack the height to stop them at the net.”

The camp is the final summer tune-up before the program’s first practice. It’s also the final part of a summer-long volleyball regimen by the Alice girls.

The girls participated in a month long summer league program at Alice High School in June. In July, a select few participated at the tournament in Tuloso-Midway. The team qualified for the silver bracket tournament play after two days of pool play. They have been attending ope-gym and strength and conditioning daily.
