Arnold possesses over twelve years of commercial real estate experience, eight of which were within the wireless industry.  His specialty is working with landlords typically recognized as challenging, such as large corporations and municipal jurisdictions.  Arnold recognizes that establishing trust with large entities is crucial, as it leads to long-term relationships and future deals.

Prior to entering the wireless industry, Arnold was a commercial realtor for The Abbey Company, a large owner/operator of commercial property in southern California.  He was responsible for all the real estate lease transactions for a large portfolio of properties, ranging from retail centers to industrial parks located between the San Gabriel Valley and Long Beach.

John Koos, Principal

John Koos is a principal in Core Communications Group.  He is a leading entitlements manager in the wireless industry.  During the past eight years, he has been identified as the individual who has been able to get the seemingly impossibility facility approved.  It is through John’s unique approach to consensus building with affected communities, identification of particular jurisdictional nuances, and long standing personal and political relationships that have set him apart from his counterparts.

John brings wireless project management experience to the table.  He has held the position of project manager for large projects, managing a multi-disciplinary team of up to twenty people, leasing through construction.  Unlike many “zoning managers” working in the field today, he considers the full scope of wireless development.  From the site selection phase to acquisition to construction completion, John understands the interconnectedness of all parts of the site development process and doesn’t abandon the site after a zoning approval is secured.

John’s forte has been to take over competitors’ failures and turn them into successes by rescuing “denied” projects and transforming them into “approvals”, including many high profile appeals in the City of Los Angeles and the City of Santa Monica.  Additionally, John has been instrumental in changing city municipal codes to serve his clients, including the zoning codes of Los Angeles, Colton, Buena Park, Anaheim and Tustin.

John served as a City of Anaheim Planning Commissioner from 1998 to 2003 (serving as Chairman in 2001).  He served on the Orange County Transportation Authority’s Citizens Advisory Committee from 1999 to 2003 (Vice Chair, 2001-2003).  He successfully ran a $111 million school bond campaign for the Anaheim City School district in 2002.  John is an active member of the Orange County Public Affairs Association.  He formerly worked at the Southern California Association of Governments.  John holds a Bachelor of Science degree in Urban and Regional Planning from California State Polytechnic University, Pomona.  He currently resides and serves as a Planning Commissioner in the City of Brea.
