"It’s always a joy to work with Gillian! Most recently, I worked with her in early preparation to play Mama Rose in Gypsy on Broadway. She’s a force; able to dive right into the music with excitement, encouragement, and steady guidance. From helping me prep for an agent audition to playing a leading lady on Broadway, I’m thankful for her tremendous support on my career journey."

"We have worked with Gillian Berkowitz for over 10 years, and we truly adore her. She has been such a huge part of helping shape our shows over the years, and we honestly can’t imagine doing them without her. Whether it’s music directing, vocal coaching, transcribing, arranging, or creating cuts, Gillian always brings so much talent, care, and creativity to the process. She somehow always knows exactly what works for us and helps make every show feel polished while still feeling completely like “us.” She is incredibly collaborative, supportive, organized, and just a joy to work with. Beyond being so talented, she’s also one of the kindest people in the business, and we recommend her wholeheartedly."

"Gillian is a smart and encouraging coach. She quickly evaluates what you need to accomplish with your session and helps you achieve it. Whether it's learning a lot of new music quickly or polishing well rehearsed pieces, she always understands the task at hand. She helps build upon my initial impulses on material while offering an outside perspective without putting me in my head. She's followed up to see how material we worked on went in auditions and performances. She's a genuine cheerleader to her friends and students. She is a great person to have in your corner to level up your work."
