Maria Deletze

Vocals
LAB Kallithea

Born and raised in Piraeus, Maria Deletze began her artistic journey at a very young age through classical ballet. Along the way, she discovered musical theatre, a field that has been a central part of her artistic path since 2010. Musical theatre brought together her three great passions: voice, movement and acting. 

She studied Musical Theatre at Sia Koskina’s Professional Musical Theater Performance (P.M.T.P.) program at G.V. Fakanas Conservatory (2010–2013), and in 2022 was selected to participate in the Musical Theater Intensive Seminar at Berklee College of Music in Boston. 

Alongside her musical theatre studies, she studied Physiotherapy at the University of West Attica, graduating in 2016 with a Bachelor of Science degree. Her knowledge of anatomy, movement, breathing and physical function enriches her approach to voice and artistic training. 

She has received training in vocal teaching at the National Conservatory with Panos Dimas (2022), as well as in the Alexander Technique (2021) and Voice Physiotherapy (2025, Manual Therapy for Voice and Swallowing Disorders / Walt Fritz ) 

Since 2020, she has been teaching voice to actors and drama school applicants. At the same time, seeking to broaden her musical training, she studied in the professional Jazz/Pop program at Lab Music Education (2023–2026), gaining knowledge and experience from accomplished musicians and teachers. Upon completing her studies in 2026, she began collaborating with Lab Music Education schools as a vocal teacher. 

As a singer, she has collaborated with artists including Eleonora Zouganeli, Marina Satti and Leonidas Marantis, among others. As an actress, singer and performer, she has appeared in major theatrical and musical theatre productions, including The Sound of Music, Cats, Evita and The Man Who Laughs, at venues such as the National Theatre, Pallas Theatre, Municipal Theatre of Piraeus and Hellenic Cosmos Theatre. 

Voice is now at the heart of her artistic and educational practice. Her stage experience, musical training and knowledge of the human body inform an approach to vocal teaching that views the voice as a living and complex instrument of expression, shaped by the relationship between vocal technique, physical function, musicality and interpretation. Her teaching places emphasis on preventing vocal strain and creating a free, creative and enjoyable learning experience.
