How music brought us together, Rosemary, Gayle & Desi!

In 1980 Desi was hired as a Teacher and Salesperson at Gould Music in West Covina, California. The very first home organ concert was with Rosemary Bailey on the Hammond Elegante. I had never heard anything like I heard that day. Rosemary was awesome and I fell in love with her that day and told myself that I wanted to be her friend.

Later that year a Lady with her daughter came into the store and asked for the manager, I told her that the manager was not in but that I was the assistant manager. She then introduced me to her daughter Gayle Serdan telling me that she was only 15 years old but that I needed to hire her and that she was an excellent player on the home organ. The Gould Company did hire her for teaching, doing concerts and also sales. In the conversation she told me that Gayle was a student of Rosemary Baileys. As Gayle worked for us I became a mentor to her as she went on to get her Doctorate in Music Arts in Jazz Studies with minors in Music Education. When I opened Desi's Music Gayle was my first music teacher. 

Rosemary, Gayle and myself never lost contact with each other also we went different path in the music business. In the last couple of years we have gotten back together with Rosemary and I going to Gayles 50th Birthday Party.

Gayle is an awesome performer on the piano and organ. Rosemary and I have invited Gayle to be one of our special guests at Desi's Music Extravaganza 2018


And a welcome back to Anthony Cozzolino. Anthony will be doing a concert and workshop!


Rosemary Bailey

Rosemary Bailey began playing the piano at the age of five, performing strictly classical music. She soon diversified and incorporated jazz and traditional popular styles in her repertoire. By the time she was nine years old, Rosemary had begun touring throughout the United States . Concurrently, she maintained a weekly radio show, The Rosemary Bailey Show, broadcast from Chicago.

Rosemary has performed with many name artists including Victor Borge and Pete Nero as well as the Duke Ellington Orchestra. She was also featured soloist with the Chicago Symphony under the direction of Dr. Leon Stein. At home on electronic as well as pipe organs, her concert schedule has taken her to such countries as Japan, South Africa, Canada, Italy, Spain, England, Holland, Denmark, Portugal, Germany and Australia.

Rosemary’s unique arrangements involve the marriage of her classical and popular music background. Perfect pitch enables her to effortlessly field requests from the audience and adds spontaneity to all her programs. Rosemary has developed a following of musical devotees wherever she performs and her numerous recordings are sought after by young and old alike.


John Kereki

John Kereki, who is one of Desi’s most popular and expert teachers is the result of Desi’s teaching program. After serving 10 years in the military John went to work in one of Desi’s music stores. He began to “play around” on the digital pianos and discovered he loved not only the playing of the instruments, but the new and ever evolving technology of modern digital instruments. It wasn’t long before he moved to the organs. John has been playing for 12 years and is a classic example of how today’s music technology can enhance the enjoyment of making music. John now shares his love of music with others by teaching Desi’s students how to play using the automatic features of the instruments. John builds playing confidence in students of all ability levels and empowers them by taking the mystery out of the word “technology.”


Doug Bielanski

Born in the early 1970’s in Bronx, NY it didn’t take long for Doug to realize his love for music. Collecting records and tapes from a very young age, Doug wasn’t content with just listening to music; he wanted to make music. 

At Christmas 1982, Doug received his first portable keyboard. After tinkering with it for a few hours, he approached his parents to take lessons.  He took lessons for less than 3 years at the Nelson Varon Organ Studios on Long Island and soon began to outplay his instructor. From there, he self-taught most everything he knows today. His style of playing is unique and varied; from classics to standards, to Latin and modern day electronic dance music. “Sometimes I will create complete arrangements using traditional organ technique to showcase my talents and ability while in other arrangements I allow the instrument being played to showcase its ability.”

During the late teen years through his middle 20’s, Doug had the opportunity to freelance for the Yamaha Corporation of America promoting the HX Electone organs. Setting up in Mall Kiosks, he and other local artists would play and sign people up for the “Play For Keeps” lesson plan. During this time he also performed many concerts for the Tri-County Organ Club as a hobbyist player. In addition, Doug joined the Amateur Organ Tape Club where he corresponded with other amateur organists from around the globe sharing his thoughts on music and recording songs on cassettes for the other members. “The Amateur Organ Tape Club really helped me to perfect my playing technique and showmanship as each correspondence sent was like a concert recording tape reaching homes throughout America and the United Kingdom. Their feedback throughout the years was critical in allowing me to hone in on my strengths in delighting others with my playing.”

Owning a total of 12 organs throughout the years, from beginner spinets to flagship consoles, the pinnacle of organs is finally owned- The Roland Atelier AT-900 ATUP-EX.  “The Atelier has allowed me to express myself in new ways. Since owning this instrument, it has re-ignited my love for making music.”

Today, Doug works as the Director of Sales and Education for Proctor and Gamble. He is married to his partner of 18 years and resides in NJ. While the organ is a hobby, he takes the opportunity to involve himself with any activities to express his talent in music for people. Winner of the 2014 Roland Atelier National Competition- Hobbyist Division, Doug continues to delight his worldwide followers on YouTube with his at-home performances. 


Stan Koyama

Born and raised in the greater San Francisco area, Stan became interested in making music at a young age. His parents provided him with a piano where he developed the beginning stage of what was to become an exciting musical career. After graduating from San Francisco State University, Stan went on to capture first place in both Yamaha and Roland Organ national competitions. His professional credits include numerous international concert tours throughout the U.K. as well as central Europe. He currently resides in the Tampa area where he is an avid Roland Atelier artist and private music instructor.


Chris Anderson

Chris Anderson started playing the organ at just 5 years old and began playing professionally at 12. Chris is a renowned performer who represented the Hammond Organ Company in the 1970’s throughout the U.S. and internationally as well. Joining Yamaha Corporation and retiring from Yamaha after 26 years. Missing performing, Chris joined Roland Corporation and enjoys playing again for audiences and for fun at home too! He is much in demand as a concert artist throughout the U.S. He served as one of the judges for the 2012 Atelier Festival in Las Vegas.


Anthony Cozzolino

Anthony Cozzolino has been playing on keyboards since 1972.  He started playing organ in 1977 after 5 years of piano lessons, being educated in the Mildred Alexander Method of playing.  In the late 1990’s he started with Radio City Music Hall organist DyAnne Awe.  Over the years he has had the fortune to be able to work with such modern greats as Hector Olivera, Rosemary Bailey, Jim Vogelman and Choy Lozada both professionally and personally,  asking questions and learning skills that they had acquired over lifetimes of playing.

A former Fashion Industry Executive, he lived as a New Yorker until 2016. Anthony was on the Board of the New York Theatre Organ Society; a staff organist for Chaminade High School’s Wurlitzer/Morton/Austin hybrid 3 manual 5 rank theatre organ with 1,143 pipes; and concurrently ran Maestro Music Centers on Long Island from 2006 until he moved to Florida.  At Maestro he taught hobby players and children to play and love music, and was the exclusive dealer of Roland Atelier, Roland Classic, Rodgers, Lowrey Virtual Orchestra and Roland Pianos.  During his time there, he started a web based YouTube channel under ‘acozz333’, providing free playing tips and product demos.

Anthony has been a Tampa Florida resident since 2016, and when he has free time, spends it in Tampa Theatre’s atmospheric movie palace auditorium listening to the 3 manual 14 rank Mighty Wurlitzer while gazing at the twinkling stars on the ceiling.


Cindy Soriano

 Cindy's love of music was gifted to her by her mother who was a classically trained pianist and organist. Piiano and classical organ lessons began at the age of six. Music study continued on into high school at the University of Redlands. A busy career teaching high school history and economics eventually drew Cindy away from her music. 

After retirement in 2001 Cindy came back to her music in a whole new way. A friend who worked for Roland/Rogers asked her to become a Club Roland teacher. She had never played instruments with automatic accompaniments, rhythms, and one touch programs. This opened a whole new world of music making—recreational music making. More fun was learning all the tools of today’s modern organs that make everyone sound like a pro. She developed a love of playing Latin, Jazz and Big Band. She often returns to the classics but gives them a new twist by adding jazz accompaniments. 

Cindy has been working for Roland dealers for sixteen years as a teacher and workshop facilitator. She was on the radio for five years with her own talk show entitled “Health, Wellness and Music Making.” Cindy is also a voice over artist and can be heard on Roland piano commercials and in video narrations about Roland keyboard products. 

Her mission is to bring the joy of making music into as many lives as possible.
