The very professional, and comprehensive care pertaining to my voice issues I would rate at 5 stars. Karen Sussman, the founder of the Professional Voice Care Center, has helped me through a most difficult time with my voice issues. Over a period of time, the voice therapy sessions with Karen have proven to be an invaluable tool in my recovery. I would recommend Karen to any friend, or family member as it pertains to voice issues. Her knowledge and compassion make Karen a leader in voice care. I could not give a higher recommendation!
