"Hilerie has been an incredible, inspirational, teacher, friend and mentor for both of my daughters, encouraging them to be their best in all of life's struggles and adventures through the pursuit of music and excellence.

Hilerie manages her lesson times and plans effortlessly- with time for friendly and purposeful chat, constructive critiques, instructions to prepare for the next lesson, to cover lesson goals and, of course SING! Lessons are truly just plain fun, and we always completed the class with a sense of having accomplished something significant.

Hilerie takes the time to get to know and listen to her students and families, developing goals about what is wanted and needed from vocal lessons-  preparation for festivals, auditions, performances, recitals, choral rehearsals, family duets, or just self-satisfaction- she is a unique and extremely gifted teacher!  Great for beginning or advanced vocalists of any age!

Personal, Private, Challenging, Inspirational- time with Ms. Klein-Rensi is time well spent."
~Mary Beth Willis


"I LOVE Hilerie, both as a friend and a coach.  I was reluctant to start taking lessons in my mid-50s because I was convinced that nothing could be done to mend or improve my aging voice, especially since I had never before considered the proper method for caring for and using my vocal chords.  Boy, was I wrong!  Since I started working with Hilerie, my band-mates have commented on my progress.  My toughest critic - my wife - has noticed, too.  I’m more comfortable singing on stage and my stamina has improved tremendously.  Hilerie is patient, encouraging, and most of all, she knows her business.  Her bright personality, sharp wit and delightful sense of humor all help to make lessons an enjoyable experience.  I would very highly recommend her to anyone - at any age - who is interested in improving his or her confidence and singing voice."  ~Gary Ingraham



"I have been working with Holly for a little over a year now.  My experience has been extremely positive and encouraging from the beginning, and Holly has been compassionate and supportive as I develop and expand my range, address specific vocal challenges with simple and effective methods, and when working on challenging material.  More than anything though, Holly has encouraged me to express MY unique voice, as well as help me to continue to build confidence in my instrument."  ~Laurie Kudis, Charm and Chain


As both a friend and a teacher, Hilerie is inspirational, encouraging, knowledgable and positive. We have learned so much in the 18 months we have taken lessons from her. As singers who are performing every weekend, our vocal health is critical to our career and Hilerie has made our voices stronger and healthier. We are constantly thankful for her guidance and support each week as she strives to make us better singers and performers. She is an amazing mentor and we feel so blessed to be her students!  ~Lauren and Hannah Hobbs, The Hobbs Sisters


"In the short time we have been with you, Kara has developed so much as a singer AND person.  You've helped her tremendously!  Can't wait to see what the future holds! "  ~Dedra Rantovich



"I love studying with Hilerie. I have experienced a marked improvement in my technique and singing has become easier than it ever has been.  Hilerie also has a wonderful way of making music come alive - she is as excellent a coach as she is a technician.  She also has a positive and uplifting attitude that is infectious."  ~Sara Botkin



"Hilerie is the most nurturing and personal voice teacher.  She utilizes her unique mix of world-class technique, acting ability, and passion to mold her singers into charismatic and riveting artists."  ~Sean Michael Plumb


"Hilerie is a fantastic teacher.  I remember coming in when I was around twelve years old and feeling so nervous that I was gonna have to sing opera or that the teacher that my mom had set me up with was gonna be mean or harsh to me.  But that wasn't the case.  Hilerie was friendly and down to earth.  She saw my potential and was as excited about my singing as I was.  When I was having a hard time motivating myself, she was there to push me forward to be the best that I could be.  As time went on, she became more than a teacher.  She became a mentor and a friend.  I miss and love her dearly and I don't regret a single thing that I did while I was under her teaching.  I am still inspired by her to this day and I'm so excited for what she's doing in Pittsburgh.  She definitely changed my life for the better, in more ways than one." ~Cassie Relyea



"Hilerie is not just interested in your growth as an artist; she is also interested in your growth as a person. The two go hand in hand. She breaks down singing into something relatable and makes you fully aware of every aspect of your body, and how it connects to singing. Over the past year, being a part of Higher Voice Studio has changed my voice for the better. I would not be where I am today without her incredible teaching technique and guidance."  ~Johnny Luoma


"...let me preface this by saying I may be a little sentimental in my discussion of this topic.  I can't help it.  Those four plus years of lessons were the years I was figuring out who I wanted to be and those 30 minutes to an hour were critical, acting as a foundation for all the singing and artistry that has happened since.  I can't be the only one that you've taught that was inspired to take singing beyond the initial goal when they walk through the door for their first lesson.  I learned that singing grows with you.  It can go from fun and games to a tool for soul searching and all that's in between.  Without your lessons I never would have thought that singing was a valid and worthwhile art form and career path, though certainly difficult.  I learned about trying to have patience with myself and accepting that some things are a constant battle (see: tongue tension).  It's never ending!  What didn't I learn from you?  I could write an essay on all the things I got out of lessons with you.  Technically?  Like I said, a foundation for all the work I continued - breath, posture, phonation...  All pondering on the matter aside, this seems like a good time to thank you.  You were a great voice teacher, but beyond that you became a great mentor.  I owe you more than I could ever say."    ~Ciara O'Neill Mendoza


"As an adult male with a weekly show, as a vocalist and performer of children's music, I wanted a vocal coach who understood the theatrical elements of performance and would take my children's music seriously.  Hilerie could do both and with such insight, that along with improving my vocal technique, she was also improving my shows with suggestions that ranged from nutrition, to audience perception, to developing and keeping a winning attitude.


If Hilerie was the vocal coach for a president of The United States, not only would the president use much better breath control during his speeches, but he would legislate that all supermarkets carry nothing but organic food harvested using sustainable farming techniques, his foreign policy would be so good that it would usher in a whole new era of world peace, and we'd all have such a winning attitude that the economy would be going straight up with no sign of stopping!"

"I started going to Hilerie in June of 2012.  Ever since then, I have been making significant improvements at each lesson. Not only has my voice become stronger, but when I sing, I am singing in a healthy way.  At first, I was nervous to go to lessons because I had never done them before.  I just sang without thinking of how I was using my voice.  Hilerie helped me to realize that if I am not using the correct and healthy technique while singing, then I can potentially damage my singing career.  I cannot express how helpful going to voice lessons with Hilerie has been for me.  I have heard such a strong improvement in my voice and I am so glad that I have the opportunity to work with such an amazing woman!" ~Emily Palma



"Working with Hilerie has been a tremendous growth experience.  I came to Hilerie as a working musician, having played over a 500 paid gigs, corporate events and weddings.  Nonetheless, I wanted to address my technique and the finer performance points.  Hilerie was right there with me from the start.  We first evaluated my technique through my vocal and tonal range and found several areas that I could improve.  What we started two years ago has blossomed into a consistent vocal technique that I can use across genres and vocal tones.  And the results have been noticeable!  The true test of a musician is with a top-notch producer.  One recent session in the studio, I did a retake of a lead vocal chorus and I made a mental note to relax and open my airway.  Well my producer noticed right away, and we got a final recording!  My lead guitarist has also commented on my improved dynamics, increased tonal range, and acute phrasing.  All these improvements, and many more, are attributable to my work with Hilerie.  She has been a fantastic teacher of technique and repertoire!  


Moreover, she has come to be a friend and confidant that I know I can trust.  She is simultaneously honest and caring.  She knows firsthand how this process of learning and practicing singing can be very humbling, and to do it fully, one must be willing to be vulnerable.  I know that my vulnerability is in compassionate hands with Hilerie and nonetheless I will get honest, professional feedback.  For that I I am truly grateful!  When I add in the Masterclasses, recitals and singer/songwriter workshops that I’ve participated in, I know that I’m in a professional vocal studio with Hilerie and Holly.  The Masterclasses have been a blessing because they show me how other students and professionals are working on the same technique issues; I get feedback from other students on my performances; and I’m exposed to music I wouldn’t hear otherwise, done in interesting and original ways.  


Finally, the extra events keep me tuned in to the fellowship of the Higher Voice Studio with singers of varying ages, genres and experience levels; all of them doing exciting things like live gigs, videos and recordings!  And from all this activity I get ideas about new challenges for me engage and many ways that I can continue to grow as a singer, a musician, and a human being!" ~Evan Dean, Evan Dean Band



"I am a guy who is well over 50 and had never performed or taken voice lessons, but had always loved to sing.  Music had always been a source of inspiration and personal growth for me.  My goals were to sing more often, to sing better, and to explore my potential.  Working with Hilerie was a WONDERFUL experience.  She is very positive and encouraging.  She creates a fun and relaxed atmosphere, where you feel like it is ok to take chances and challenge yourself.  I learned so much from Hilerie, which helped me to improve my range, tone and confidence in singing solo.  Studying with Hilerie is good for your heart and your soul!"   ~Don Kain


"My daughter started with Hilerie when she was just 5 years old. Over the four years that she took lessons she learned a wide variety of music along with many vocal warm ups and exercises to enhance her singing. She really looked forward to working with Hilerie every week, and has been singing on a regular basis at our church ever since. In her own words, 'Miss Hilerie Rocks.'"  ~Tina Otis



"Hilerie is such an awesome voice instructor, but more than that, she is a great person and friend. She becomes her students' friend and mentor, helping and encouraging them along the way. Of all the instructors I have had in the past, Hilerie is my favorite. She was able to teach me things that none of my other instructors ever did. She really cares about each of her students. When my daughter was experiencing some major health problems, Hilerie was a great friend and encouragement to me. She took time to find information about doctors and diet that she felt would help, and she kept in touch even when we stopped lessons for awhile. She was genuinely interested in our lives. Even though she has moved her studio to Pittsburgh now, she still keeps in touch with us and offers to give us lessons whenever she comes in town. I love Hilerie and truly miss her!"  ~Lori Relyea



"When I first came to the studio, I was skeptical about how much vocal improvement I would see. Trust is rare, and to trust someone with your voice, your soul, is no easy task. I trusted Holly from our very first lesson.  Together, we've worked on my voice for one year and I am absolutely stunned at the difference between then and now. The pace of the evolution is insane!  It has been such a dramatic transformation, not only in my voice, but also in my confidence.  All of it, I owe to Holly.  I used to sing at the volume of a whisper.  Now I have a powerhouse voice.  Techniques taught at the studio are top notch.  If you are passionate and dedicated in following her instructions, Holly will take your voice to new levels.  You CAN have the voice of your dreams, and you WILL surprise yourself, guaranteed.  Lessons are never boring, after all, singing is an adventure!  Holly and I have a blast, and I truly enjoy and anticipate my lesson each week!  Trust me, there is no better place to begin your vocal journey than Higher Voice Studio.  Joining has been one of the best decisions of my life.  Hilerie Klein Rensi and Holly Van Hoey, changing lives one voice at a time!  Give them a call. In one year's time you'll be congratulating yourself on the best decision you ever made."  ~Haley Yanko
