STUDENT COMMENTS ABOUT MAREN MAHONEY
“Maren was extremely knowledgeable about the content of the class. She also asked what we really wanted to know about, and tailored the class on the fly which was very beneficial.” Steve, IT Architect
“One of the best instructors I have ever had. She makes very difficult concepts quite easy to understand.” Marsha, Telecom Engineer
“Maren was possibly the most enthusiastic instructor I have ever encountered in all my training. She seemed to be very comfortable with training this subject.” Roger, Network Engineer
It was an absolute pleasure having Maren as my instructor. I came into the course hoping to gain a better understanding of Cisco Call Manager and how it worked with the VOIP system as a whole and at the end of the course I absolutely felt that I had achieved that.” David, Help Desk Technician
“The class was great. I thought Maren did a great job. I’ll definitely be going to you guys for more training in the future.” Tom, Network Engineer
Mike Keutzer has been involved in information systems for almost 30 years. His IT career started in the Marine Corps where he spent 8 years as a computer technician working on radar defense systems. He carried that experience to 20+ years of work in the private sector. After leaving the military Mike spent time working as a technician maintaining computers and printers, managing and supporting Mainframe, AS/400, Novell, UNIX, Mac, and Windows networks – mostly within the world of Contact (Call) Center environments.
Mike joined SLI, formerly CCTI, in 1997 as a technical instructor teaching classes in the Microsoft curriculum. He then earned his designation as a Certified Cisco Systems Instructor and began teaching courses on Cisco advanced routing and switching, with an early exposure to the voice world of Cisco. Mike also assisted in the design, implementation and operation of SLI’s voice and data networks.
In 1999 Mike took a leave of absence from SLI to work as a network engineer at McMurdo Station in Antarctica. His duties included upkeep of the network infrastructure for McMurdo Station and the South Pole station, maintenance of satellite connectivity back to the U.S., and maintenance and security for Unix Domain machines (DHCP, DNS, SMTP) for mcmurdo.gov. Working in “the real world” again provided the much needed experience necessary in the classroom environment.
Upon returning to SLI, Mike was afforded the opportunity to become one of the first instructors certified to teach the ICM product (ICR at the time, formerly Geotel). Mike also continued to augment his education of the Cisco Voice world with courseware and implementation of early CallManager and Unity systems, as well as IOS based Voice classes and implementation. Back in these early days, UCCE or IPCCE hadn’t been formally ‘invented’ – ICM at the time was mostly integrated with the Legacy Voice systems of the world. Being fortunate, Mike was able to see the current Contact Center Enterprise environment (which includes ICM as a core component) from birth to its current state of maturation, and is now where he spends most of his instructional duties. His expertise in the various components of the UCCE solution(s), as well as his data/application/voice background allows him to tailor each delivery to meet the needs of his students. He has authored several contact center training materials, including the current UCCE courseware (AUCCE1, AUCCE2, DUCCE) for Cisco, as well as efforts at bringing Enterprise Chat & Email (ECE) to the table. Previous development efforts included Customer Voice Portal Implementation (CVPI 3.X, 7.X), as well as various on-line courses including UCCE Design and Support (7.X), and UCCE Design, Implementation and Support (8.X). He is also the author of several Custom courses offered by SLI, including UCCE with CVP, UCCE with IP IVR, ACCE-CVP, DBUCCE-CVP, CCCEF and VFCC.
Starting in April 2018, Mike has been involved in the Broadsoft/CC-One/CJP effort by becoming a CJP-Expert and a CJP instructor.

Mark Wilson’s first job in the IT industry was in the mid 1990’s after college and a few years in the Army. His experience started with hardware and desktop support, eventually migrating to Server and LAN Administration and developing cable modem systems and ISP Services. Mark then joined SLI (named CCTI at the time) in 1999 teaching Cisco courses on routing and dial-up networking (yes – analog modems). He feels that he got into voice backwards by teaching courses on Cisco ICM before migrating to Call Manager, Unity, and CRS (an early name for UCCX) which created opportunities to teach a few courses in Europe.
Several years later, Mark was offered a chance to work for Avaya, focusing on large contact center customers. He worked there for 10 years as a sales engineer and architect. That was followed by an opportunity to return to his roots performing support for networking, voice, small contact centers and other contract services.
Recently, Mark returned and is excited to be back teaching at SLI. His current focus is contact center courses, but given how many different areas he has worked, he reserves to right to teach other technologies.
