Born in Wilmington Delaware in 1947, Geoff played in local bands.

In January 1966, he left American University to join NY based Mercury artists Blues Magoos. Between '66 and '69, they recorded four albums, two of which were platinum, and a top five single, "We Ain't Got Nothin' Yet". The peak of their career was in 1967 when they toured four months with Herman's Hermits and The Who (Hermits were the headliners). During those he became fascinated with recording and engineered some of the Magoos last album.

In the summer of 1969, Geoff went back to Woodstock where he played in bands with Tim Harden, Dave Sanborn, Paul Butterfield and Buzzy Feiton. In 1970, Geoff became a staff engineer at Sound Ideas in NYC which was equipped with API consoles #1 and #3. There he honed his skills and besides recording, designed and managed the construction of four studios.

In 1977, Geoff left Sound Ideas for SoundMixers NYC, and in 1979, became an independent engineer. In 1982. he opened his own studio, Nimbus Nine, which grew to four rooms, one API, one Neve, one Trident, and one ProTools.

Since 1970, Geoff has designed and built more than 20 recording studios for music, film and commercial production. In 1994 he built the all analog "BIG Blue" in Katonah NY for the recording of Joan Osborne's premier album, "Relish". In 1996 he built a combo analog/digital studio in Tuxedo Park for Cyndi Lauper's "Sisters of Avalon". His most recent studio is the multi-million dollar music production facility in Saint Petersburg Florida, Big3 Entertainment.

In 1993, with is expertise, Geoff started manufacturing his own line of audio equipment. The first product was a combination mic-pre/eq. This all discrete Class "A" unit was based on the legendary Trident A Range circuits by Barry Porter. Next was the FET Compressor. In 2000, production began for full size Class A recording consoles in frame sizes from 16 to 80 inputs.

New for 2004 are a 4 channel 1U Mic Preamp, and a console specifically designed for digital audio. This new product has 10 band graphic eq's and a FET compressor on every input. The center section provides full studio monitor and meter control. The monitor section mixes multi channel audio from digital workstations in the analog domain. This eliminates the shortcoming of the computer in audio summing.
