MRS. GENA ROBBINS – Contact info: or cell 817-637-4109
My name is Gena Robbins. This is my 12th year teaching voice at Keller High School and my 14th in Keller ISD. I am a graduate of Baylor University, where I received my degree in vocal performance. While there, I performed in many operas, sang with the A Cappella Choir and Chamber Singers, and was active in the adult and college choirs at my church in Waco. During that time and since, I have had experience teaching music both in a classroom setting and privately and have been an active member in my church music program (adult and youth) in several capacities over the years. I have also been in several community musical productions and plan to audition for future shows locally. In the spring of 2013, I released a solo CD consisting of hymn arrangements and other styles of Christian music. You can hear excerpts (and hopefully place an order) on my website: www.genarobbins.com
All three of my children graduated from KHS, so I have a vested interest in the quality of the programs offered to our students – particularly Fine Arts. Singing should be a source of pleasure for the performer as well as the listener. It is my goal that my students come away with a better understanding and appreciation for the skill that is involved in both. Studying voice and learning to sing properly will give these students a skill they can enjoy throughout life, whether or not as a profession.
MR. WeiShu Tsai - Contact Info: / 940-465-9889
My name is WeiShu Tsai. It is my pleasure and honor to be teaching voice at Keller High School. I am also teaching voice at Hillwood Middle School, and other music academies around DFW. Previously, I served as a Teaching Fellow at University of North Texas for three years teaching undergraduate voice lessons, along with voice classes for music majors and non-music majors. I was also teaching at Guyer High School and Harpool Middle school in Denton ISD.
I perform as a soloist in operas and concerts as well as serving as a choral scholar and assistant director at Flower Mound United Methodist Church. Before my studies at UNT, I was a member of the Taipei Philharmonic Symphony Chorus and Chamber choir for 5 years. I found my passion in singing and acting during those choir rehearsals and performances. I would love to share my passion and knowledge about the human voice and help students to be successful and build healthy singing habits.
I now live in Lewisville,TX with my wife, soprano MengJung Meg Tsai, and our three- year-old son, Channing.
