Emerging international violinist, Heidi Hatch, began studying music with her father, American violist Peter Hatch, before she was four years old. Her talent, even at such an early age was precocious, and has continued to impress all who hear her. Her former mentor and teacher, the legendary Soviet-era violin guru, Professor Abram Shtern once described her as "a rare talent, a natural on stage... and her playing is possessed of an emotional urgency and musical understanding far beyond her years." In December, 2005, she was featured in an interview in the Spanish Magazine "Melómano".

Already by the age of 12, Heidi had graduated from the Lark Conservatory in Glendale, California, where she was a scholarship student; an accomplishment normally reserved for 18-year-old students that have studied for 10 years or more at the conservatory. Heidi made her American professional debut as soloist with orchestra in Sarasate's "Carmen Fantasy" with the Glendale Symphony at the age of 11 where her performance provoked an enthusiastic standing ovation. At 12, she made her Spanish debut with the Murcia Symphony Orchestra in the Conus Violin Concerto with special concerts in Albacete and Alicante and immediately following the concert was re-engaged as soloist for the orchestra's regular subscription concert series in Murcia. She has since appeared with other local (California) orchestras in Wieniawski's "Polonaise in A-major" and the Max Bruch Violin Concerto, and with the Alicante Symphony in Spain. She played her first full recital at the age of 10 in a program that included music by Beethoven, Sarasate and Paganini.

Heidi Hatch has been the winner of numerous awards and prizes, including a 2006 Young Musician's Foundation Competitive Scholarship, the Antelope Valley Symphony's Young Artist Competition, the City of Glendale's Talent Search Contest two years in a row, and the Los Angeles City Elementary Schools Music Association (LACESMA) Scholarship Award. which she won at the unprecedented age of six. She was awarded a prize as "Most Outstanding Spanish Violinist" at the Sarasate International Violin Competition in Pamplona, Spain and recently was awarded one of only two "Special Prizes" at the Hong Kong International Competition in China.

As a student at R. D. White Elementary School in Glendale, California, Heidi was often cited as Student-of-the-Month and designated three times Ace Honor Student for Academic Excellence. She later graduated from high school as Valdictorian of her class at the Verdugo Academy in La Crescenta, California. Upon application for entrance at the University of Southern California (USC), she was nominated for the "Trustee Scholarship" which is a full-tuition scholarship based exclusively on academics. Later, she graduated Magna cum Laude with a bachelor's degree in music as a student of Alice Schoenfeld.

In 2008, she played the Saint-Saëns Concerto in Albacete and Murcia, Spain with the Murcia Symphony and Mozart's Concerto Nº 5 in the Spanish city of Roqueta de Mar, in the province of Almeria. A founding member since 2007. she participates every summer in the music festival of the Spanish city of Villanueva de los Infantes (Ciudad Real) where her performances of chamber music and the solo violin repertoire are enthusiastically received by the public. In 2010, Heidi toured as soloist with the Bucharest Symphony in 8 performances of Havanaise by Saint-Saëns and Fantasy Caprice, Opus 22 by Vieuxtemps in major Spanish cities from Galicia and Catalunya in the north to Toledo and Almeria in the south. That same year, she recorded several programs for Spanish National Television that are still broadcast on weekends throughout Spain and internationally via satellite.

Heidi, as a scholarship student at the Glenn Gould School (Royal Conservatoire) in Toronto studying with Professors Barry Shiffman and Paul Kantor, earned the coveted Artist's Diploma. Serving as concertmaster of the orchestra from time to time, she also performed Bruch's Scottish Fantasy, as a result of winning the school-wide concerto contest. While still a scholarship student of Alice Schoenfeld at the University of California in Los Angeles (USC) she served as concertmaster of the YMF's Debut Orchestra (the premiere pre-professional orchestra in Southern California). She has appeared with the Santa Monica Symphony as soloist in Glazunov's Violin Concerto and in the same concerto, with the Burbank Symphony in the Ambassador Auditorium in Pasadena California.

As the eldest daughter of Spanish citizen, Francisca Martinez Calixto, Heidi enjoys dual American & Spanish citizenship and is fluent in Spanish and English. In her spare time, she enjoys reading books, writing poetry, playing music with her sister, Alexis, sailing on the Pacific ocean with her family, and taking care of her magnificent dog, an Afghan Hound named Gypsy.
