In 1980, David moved to California to enter the Technology field.  For 10 years, David was Regional Director for Victor Technologies, responsible for the sale of PC’s and POS systems to end users and Channel partners in the West.  From there it was a natural progression to take his intimate knowledge of the computer industry and the Western region and offer his services to client companies and prospective candidates as a recruiter.  In 1989, David joined a California search firm and successfully established their Pacific Northwest and No. California technology practices, before leaving to establish Corporate Dynamix.

David’s sole specialty is in Technology recruiting with a focus on Enterprise and cloud-based Software.  He recruits only Sales/Sales Management Executives in the 14 Western states. Start-ups with emerging technologies as well as medium to large Software, Services and Hardware companies are David’s area of expertise.    Throughout his 30 years of recruiting, David has successfully placed more than 1800 candidates in the Western U.S.

David believes an outstanding recruiter must provide outstanding service to both employer and candidate, through an in-depth understanding of the employer’s products, needs and corporate culture; careful screening of each candidate’s credentials, background and references; a precise pairing of the right candidate to the right position; clear and concise communication to the employer of the candidate’s strengths and weaknesses; and persistent follow-up throughout the search process.  “This is a service business“ says David, “and I have to bring exceptional value to everything I do for my clients and candidates.”  David prides himself on the multiple placements he has done with many of the largest technology firms in the nation.  As sole proprietor of Corporate Dynamix, he brings a very personal approach to working with every candidate and has helped manage the careers of many job-seekers beginning with their first job.

He is recognized by his peers and clients as an expert in his field and has been interviewed by Business Week, and The Wall Street Journal.  David is also referenced by The Recruiting Lab in their series, The 15 Critical Habits of Highly Effective Recruiters and in the book, Sales 2.0 Improve Business Results Using Innovative Sales Practices and Technology. David was a speaker at the Silicon Valley Telebusiness Alliance on the topic “Choosing a Search Partner,” which he delivered to the top 100 inside sales managers of various software organizations.

David relocated from California to Scottsdale, Arizona 20 years ago.   He is happily married, enjoys weekly golf games year-round, and is busy co-parenting 3 children.
