Guadalupe Ramos

Hola, I am from Monterrey, Mexico but migrated here during the 1980s. I was unable to finish high school, so I understand the importance of an education and the limitations that come from not having one. I am currently working on getting my GED. I am now managing Regios Distributors, a wholesale company of Mexican products. I am a happy father of 2 who also enjoys Netflix and walking my dog.
