VOICE LESSONS

Mr. Allen is a friendly, experienced voice teacher, singer-songwriter, and performer who is passionate about helping young singers grow in both confidence and skill. He graduated from Texas Christian University (TCU) in Spring 2023 with a Bachelor of Arts in Music and a minor in Psychology, giving him a strong understanding of both vocal technique and how to connect with students on a personal level. Isaiah tailors every voice lesson to fit the student’s age, goals, and style—whether they’re new to singing or preparing for All-State auditions, musical theater roles, or recording projects.

As a performer, Isaiah has had many exciting opportunities. He released his original single “Abba Father”, which is available on all streaming platforms, and performed standout roles like Audrey II in Little Shop of Horrors and a sailor in The Little Mermaid. His performance in Little Shop was chosen to appear at the Texas Thespian Convention, and he even had the rare opportunity to work with actress Janine Turner on her original musical Belva. He is also a 4-year Texas All-State Choir member, earning 1st chair in the Mixed Choir three years in a row. One fun fact: Isaiah was invited to audition and perform with Disney, but turned it down to follow a different path.

Isaiah is also very active in his church community, Apostolic Church Dallas, where he contributes musically and spiritually. His faith deeply informs his sense of compassion, mentorship, and purpose in working with students.

Outside of music, Isaiah enjoys playing volleyball with friends, and he’s currently learning French, Spanish, and Italian to better connect with different cultures and musical styles. His students love that he makes learning fun and inspiring, helping them become not just better vocalists, but more confident and expressive people.
