Can you help? Question about puberty?

When going through puberty do you usally start when your father did because I am going into my softmore year in high school and I still havent gone all the way through puberty. I have pubic hair, arm pit hair my voice is deep and I am about 6'2. But my is still really small. My dad told me that he finally developed going right into his softmore year. So I was just wondering if I may fallow in his time of hitting puberty
