Quality Governance Program
QUALITY GOVERNANCE PROGRAM
GUE invests considerable resources into the development and maintenance of the highest quality instructors and diving courses in the industry. This extensive process is further supported by a Quality Governance Program that seeks to safeguard the quality and safety of all GUE-related diving activity. This program primarily monitors GUE courses and instructors but also strives to support safe diving practice within our communities.
This program is supported by:
- The Quality Control Department, tasked with ensuring standards compliance by instructors and within classes
- Quality Assurance Department (lead by the Director of Risk Management) that proactively seeks to identify areas of organizational improvement
- Training Administrators that develop and organize the important program and administrative details
- The Designated Trustee of Standards and Procedures who maintains the integrity of standards and protocols
- The Board of Directors, which monitors each element while also conducting its own evaluation and proactive development initiatives

Maren Isigkeit
QC BOARD MEMBER
Maren Isigkeit is an IT specialist, working and living in Northern Germany. In 1991 she completed her first scuba dive in the Baltic Sea and realized that with a background as a competitive swimmer and water polo player, diving was just a logical addition to her love of being in the water. As a GUE Instructor, she teaches the Foundational and Recreational curriculums and is an addicted cave diver. Before these water-filled beauties attracted her attention, she had already fallen in love with the most elegant and pristine way of diving: free diving. She is currently involved in cave projects in France (The hidden river project – Reseau de l’Ouysse) and GUE Project Nuttlar in Germany (Slatemine), but also loves projects focusing on the protection of marine habitats.

QC BOARD MEMBER
Walter Zagzebski is an attorney licensed in California. He has spend over 20 years focusing primarily on business and commercial litigation matters, insurance coverage and bad faith claims, intellectual property, real estate, professional liability and eminent domain. He has also represented non-profit entities in connection with various goverance and business-related issues. He is not GUE's attorney.Walter wishes he discovered diving at an earlier age, but quickly found it an all-consuming passion, having done hundreds of dives in less than five years. He took Fundamentals in early 2019 and followed up with Tech 1 in late 2020 and CCR 1 in 2021. He is hoping to catch up on cave training and CCR 2 in this coming year.
Walter is hoping that being involved in assisting GUE operations will allow him to bring his experiences outside the diving world to help create positive changes and unique ideas for GUE moving forward. He will also candidly admit that making friends and relationships with far superior divers than he might rub off in a positive way. As they say, you are the company you keep.
Walter lives in Redondoa Beach California. He has a wife, Lauri, aslo a diver, as well as two wonderful rescue dogs, both of whom regularly give curious looks at his tanks and dive gear and cannot seem to grasp the purpose of it all despite repeated attempts to educate them.
