I am a composer, arranger and pianist residing in Bronx, NY. I received my musical training at Sonoma State University near San Francisco, where I studied composition with Will Johnson.  My studies in New York included the Manhattan School of Music where I studied piano and composition with Robert Helps, and at the New School where I studied composition with Leonard Rosenmann.  I have performed in solo and chamber music recitals on both coasts, and occasionally found myself doing church and nightclub work as well. 

Classical music is my forte but I also have a love for and have worked extensively in the theatre, from vocal coaching for the New York production of Sugar Babies and the musical direction for several productions at the American Conservatory Theatre in San Francisco, to conducting musicals and operas. 
I was honored to be a 2018 recipient of the BRIO (Bronx Recognizes Its Own) Award from the Bronx Council on the Arts  and a 1982 recipient of a New York Council On The Arts/Meet The Composer grant for my Variations for Flute and Piano. I have written for a wide range of instrumental and vocal combinations including musicals and musical revues, a movie score, art songs, concerti, other orchestral works, a requiem mass, two operas, and a great deal of chamber music.  

Two CDs of my works have been released: The Omni Ensemble Plays Works of Jim Lahti and the 2-CD set  of death and the planets. (with di.vi.sion ).

My music has been heard in concerts in New York, California, London, and France as well as on the Columbia University radio station, WNYC-FM in New York and CKUA in Edmonton, Alberta, Canada.  

I am pretty much composing all the time and currently working on a new opera.  I share my music and my life with my wife Mary, an artist and actress.​
