Setting the Standard: Excellence in Marina Management
March 19, 2026 | OurPeople, Sustainability
At Guest Services, we believe that providing legendary hospitality in our nation’s most iconic waterways requires more than just operational oversight, it requires a deeply-rooted respect for the environment and a commitment to professional excellence. This February, several of our leaders at Lake Mead Mohave Adventures reached a new benchmark in their careers by receiving certifications through the Association of Marina Industries (AMI).
Marina Leadership
Marinas managed by Certified Marina Managers (CMMs) are recognized as the most professional in the business. Senior Director of Operations Lisa Duncan and General Manager of Columbia Island Marina Matt McDaniel both recently earned their CMM, joining an elite group that represents the pinnacle of the recreational boating industry. CMMs are marina professionals who have completed an extensive global training process, embracing a “stewardship-first” mindset that ensures our docks remain safe and sustainable for the communities that support them.
Lisa and Matt join our existing roster of CMM leaders, including Gabi Muskett (District Manager, awarded January 2025), Herb Riggle (Cottonwood Cove Resort & Marina), Kim Roundtree (Callville Bay Marina), and the recently retired Rod Taylor, further solidifying our commitment to high-level expertise across the region.
Empowering Daily Operations
While the CMM represents full-charge facility management, the Certified Marina Operator (CMO) certification is specifically designed for those who master the complexities of daily marina operations. This February, five of our leaders earned their CMO designation:
-
- Mike Pergola, Willow Beach Marina & Campground
- Nathan Newingham, Temple Bar Marina
- Lorrie Riggle, Cottonwood Cove Resort & Marina
- James Riggle, Callville Bay Marina
These certifications are about more than just titles; they represent a “Michelin-level” dedication to the guest experience. By prioritizing continuing education through the AMI Training Institute, these leaders ensure that from the moment a boater hits the water, they are supported by a team that values ethical conduct and operational precision.
As we celebrate these achievements, we recognize that the strength of our “small-knit but mighty” culture is built on the individual growth of our people. Congratulations to our newly certified leaders for their dedication to keeping Guest Services at the forefront of the maritime industry.
