Client Development Outcomes
Performer from New York City
I came to Aaron 4 years ago when I knew something was wrong with my vocal cords. After a few weeks of utilizing what Aaron gave me, I was producing the notes I lost in my high range again and after a few months I was shocked to feel that my baseline was stronger than before the one and only session I had with him. I am a completely different singer because of the skills Aaron gave me. This year I am leading a 1st Broadway National Tour and performing a challenging score 8 times a week. I consult with Aaron to keep my stamina strong, and I am proud to say that despite the difficulty of the show, I feel more consistent than ever. When I first met Aaron, I was often calling out of a show I was working on because I tired out quickly. I am proud to say I have not called out of a show since working with Aaron, and one number I sing at the end of act two has even gotten mid-show standing ovations. I cannot recommend him enough!

Dr. Aaron is a very talented teacher who teaches very well and has a class already prepared, and thanks to him, I have improved my English a lot. Learning English with Dr. Aaron is amazing! I am 10 years old, and he is a very punctual teacher, and his classes have a super fun methodology. It's not just a class; we do different things: yesterday he taught me to put the palm of my hand close to my mouth to feel the vibration of the 'noisy sounds.' It's like doing a scientific experiment with my own voice! We also use the camera to see the position of my teeth and lips. Thanks to his dynamic classes, I've only had 3 classes, and I no longer get stuck when speaking, and I have increased my speed to 84 words per minute. I recommend him 100%! It is a luxury to have a teacher like him. Fun, reliable, and very kind.
As the result of a rare virus I lost the ability to effectively speak or sing for nearly a year. Following successful surgery in Portland, OR, Dr. Aaron Ziegler began working with me in both speech and singing voice therapy. The ability to speak is essential to me in my business. Over about a four month period of intense therapy I regained my ability to not only speak for extended periods of time but again to sing. His experience and professionalism successfully brought me through this very difficult time in my life. I highly recommend Dr. Ziegler to anyone needing help with healing for speech and singing.
CLIENT ACHIEVEMENTS
Global Leadership
Personalized Accent Coaching Leads to YouTube Success
I've only had two lessons with Dr. Aaron so far, but I'm already impressed. From the very first session, he took the time to truly understand my specific challenges rather than jumping straight into generic exercises. What stood out immediately was his professional assessment — he carefully analyzed my accent, identified the root of the issues, and explained everything clearly. It felt like a proper, structured assessment rather than just a casual conversation. That gave me a lot of confidence that we have a real plan moving forward. We've now started working together on improving my accent for my YouTube channel, and I can already see that his approach is thoughtful and tailored specifically to me. It's clear that Aaron knows exactly what he's doing. I'd highly recommend Dr. Aaron.

Academic Excellence
Targeted Communication Training Elevates Research Presentations
Dr. Aaron is an amazing tutor. He’s super nice, patient, and always has such a positive vibe. Right from the start, he established a supportive and encouraging environment, so I wasn’t afraid to speak up or make mistakes, and he corrected my pronunciation on the spot. His classes are never boring—they’re always fun and full of energy. He’s great at explaining tough topics in a way that’s easy to grasp. He plans everything around my actual level and exactly what I need to improve my English speaking and presentation skills.

Life Transition
Structured English Lessons Build Skills for PTE Test Achievement
I really enjoyed my lessons with Aaron. He was very supportive throughout my PTE preparation, especially in the writing sections, which has been the most challenging part for me. His explanations were clear, detailed and easy to understand. I would highly recommend him to anyone preparing for IELTS / PTE.
