You can try yourself and learn by yourself. Actually this is a important characteristic for people that works in IT world. Most of my certifications and knowledges I learnt by myself, so adding knowledge to my career.
You can also start not in colleges, but in doing technical trainings. Cisco offers an very important program called Network Academy (https://www.netacad.com/). I did this program and that just changed my life. At that time I did the CCNA training, but today they have trainings related with programming and other topics more related with Information Technology.
