In 1959, Fanizadeh enrolled in dramatic arts classes to develop his acting skills. This marked the beginning of his professional journey in the world of theater. During the same year, he and several of his friends founded the Gol Sorkh Theater Group, an organization dedicated to producing theatrical performances and encouraging artistic creativity. Establishing the group demonstrated both his enthusiasm for theater and his determination to contribute to the growth of dramatic arts in Iran.
As his experience increased, Fanizadeh joined the Pasargad Group, another respected theatrical company. Working with this group allowed him to gain valuable stage experience and collaborate with accomplished directors, actors, and playwrights. These opportunities helped him refine his acting techniques and establish a reputation as a talented stage performer capable of portraying a wide range of characters.
