"I will be forever indebted to Rosemary Ostrowski for the empathetic guidance and support she so generously gave to me post-diagnosis of a vocal cyst on my right vocal fold and subsequent surgery. The success of my rehabilitation I most certainly attribute to both her vigilance and considerable skill. True Love Forever xxx."

"It's vocal yoga for the voice weary. My voice is my living. Through her coaching, she turned my vocal nodes around. She helped me to create better habits to prevent injury in the future. She did this with charm, wisdom, knowledge and encouragement."

"When I first came to you, my voice felt so broken and tired. I was unsure about where my voice would go and it tarnished the thrill of performing, writing, and experimenting. You saved my ass. You have truly given me my voice."

"With her firm technical guidance, her personalized approach to instruction and her incredible sense of humor, Rosemary is the kind of teacher everyone should have. She is clear, concise, and so observant that she astounds me. She was invaluable in bringing me out of a vocal injury and helping me retrain myself to vocalize more confidently and safely. Thank you, Rosemary."

"Rosemary has been so very committed to helping me explore my voice and performance style. This is such a priceless quality to have in a teacher, as many teachers are inclined to push a very specific way of approaching music on their students instead of giving them the kind of individualized attention Rosemary has given me. Her experience as a singer enables her to be an endless source of good advice and encouraging words. Working with her is absolutely wonderful. I am so happy to have found such a phenomenal teacher."

"Rosemary has a great way of cultivating the true potential of a singer's voice. Her belief in the power of the voice and her skill in guiding a singer to actualize that potential arise from her many years of experience singing, teaching other singers, and working with medical conditions associated with the voice. I trust Rosemary with my voice, and my voice is my life."

"I began seeing Rosemary in late 2005, and after just a few sessions I could easily see a marked improvement in my range, flexibility and also my ability to control my own voice. The great thing about Rosemary is that she teaches you what works for you, and not necessarily what works for her. She has a real gift for communicating what she wants from you in a way that is easy to understand, and therefore easy to execute. I consider finding Rosemary to be a real blessing. She has improved my confidence dramatically."

"Rosemary is a great teacher and person! She helped me through my rehabilitation after voice surgery and would check on my progress by coming to my rock gigs as well! Not many voice teachers do that, and that’s one of the things that make her so special. I am very grateful to Rosemary for her lessons and guidance in my singing career. Simply put, Rosemary is the best!"
