Your Catholic Studies teacher seems to be strangely unaware of the plain teachings of the Catechism of the Catholic Church on this subject, or is in denial of them.
The teaching of the Church affirms the existence of hell and its eternity. Immediately after death the souls of those who die in a state of mortal sin descend into hell, where they suffer the punishments of hell, “eternal fire.” The chief punishment of hell is eternal separation from God, in whom alone man can possess the life and happiness for which he was created and for which he longs.
Following the example of Christ, the Church warns the faithful of the “sad and lamentable reality of eternal death” (GCD 69), also called “hell.”
Mortal sin is a radical possibility of human freedom, as is love itself. It results in the loss of charity and the privation of sanctifying grace, that is, of the state of grace. If it is not redeemed by repentance and God’s forgiveness, it causes exclusion from Christ’s kingdom and the eternal death of hell, for our freedom has the power to make choices for ever, with no turning back. However, although we can judge that an act is in itself a grave offense, we must entrust judgment of persons to the justice and mercy of God.
She is one of them Catholics who say “An all loving God would not send anyone to Hell.”
First of all, the Church points out that people are the ones who technically send themselves to hell:
God predestines no one to go to hell; for this, a willful turning away from God (a mortal sin) is necessary, and persistence in it until the end.
Secondly, Jesus emphatically stated numerous times in the gospels that there would be people who end up in hell. Is it your teacher’s opinion that Jesus was either lying or somehow ignorant of this alleged non-existence of hell?
Can anyone give me proof of Hell from the Catholic Church and tell me what the Early Church Fathers said about Hell?
In terms of proof of hell from Catholic teachings, the above quotes I provided from the Catechism should suffice. Nevertheless, you can also bring up Ludwig Ott’s Fundamentals of Catholic Dogma, where he explains the existence of hell from a doctrinal standpoint. For example, visit this website for a brief presentation of Ott’s doctrinal points, focusing on #406 - 408. In my opinion, anyone who rejects the teachings of the Catechism and Ott’s Fundamentals of Catholic Dogma has no business teaching a Catholic Studies course.

Everyone please pray that the Holy Spirit leads her to the truth.
I will indeed do so, especially because…
Heresy is the obstinate post-baptismal denial of some truth which must be believed with divine and catholic faith, or it is likewise an obstinate doubt concerning the same
According to Canon Law, those who are culpable of an act of heresy automatically cause themselves to be excommunicated (see this article for details).
