She is really great and is very welcoming. And helps you achieve your goals. A lot of vocal coaches won't give you the choice of what music style you learn, Kelli does. And she can teach any style.

Who Knew played at a birthday party at my home, for about 50-75 guests. They performed a wide variety of music, were very friendly and easy to communicate with, and exceeded our expectations.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
We include all of the pricing in the quotes and work with each client individually. There are no hidden fees and no middle man - you are working DIRECTLY with the owner
What is your typical process for working with a new customer?
I like to start with email, getting to know the needs and so forth, then speaking on the phone and ironing out details. Contracts are simple and straight forward, too. No catches
What education and/or training do you have that relates to your work?
I have a Master's in Vocal Performance from Northwestern University - my undergrad work was in Vocal Performance, Violin Performance, starting at the Conservatory for the Arts at Wittenberg University, finishing at Northwestern - and a degree in Health Psychology from DePaul University. I have been coaching violin since age 12, dance since age 13, voice since 18, and have worked as a Producer, Choreographer, Coach with many organizations and schools, including coaching several Miss America's, American Idols, Tony winners, etc....
