Testimonials

Copywriting
“It has been a pleasure knowing and working with Cal Callahan for the past 12 years. He worked with me while I was at QUALCOMM creating ads, brochures and other marketing collateral and I also hired him on for marketing projects my agency needed for the various clients we have. From entire branding campaigns to one-off marketing pieces, Cal has never failed to deliver the same level of quality, creativity and wit that our clients have come to expect in their collateral.

“He not only delivers great work, but he is extremely reliable. He works fast and never fails to amaze me by providing me with more than I expect. I highly recommend Cal Callahan for any type of concept creation and copy writing for marketing/advertising – regardless of what industry, product or service. He thoroughly researches his subject and is able to understand and interpret what is needed every time.”

Technical Writing
Cal can be relied on for fast turnaround and on-time delivery of a quality product. He quickly understands difficult technical material and translates it into useful documents. His creative abilities and his command of the language make for outstanding technical and marketing literature. I would recommend his services without reservation.

Versatility
Cal is amazing because he’s one of the very few people who can write interesting, engaging, effective, and ongoing newsletters (one of the most difficult writing jobs) for any company or organization.

I call Cal “Mr. Persuasion.” For example, while I was proofing one of his QUALCOMM recruit-engineers newspaper ads, his prose drew me in, made me forget what I was doing, and I thought, “Wow! That sounds like a great company! I’d like to work there.”

I wholeheartedly recommend Cal for any assignment that requires skilled writing, team effort, tenacity, and the ability to quickly grasp and communicate complex concepts.
