The Team
VEN SUNAM HLAMO, Dr. Brigitte Mayr
Director
“Happiness is when the bass starts to play” – isn’t this the perfect life theme for an ordained nun?”
Venerable Sunam is passionate and joyful in everything she does and mixes “rock ’n’ roll” with a touch of German efficiency. She is a licensed veterinarian, successful IT project/program manager, and has worked as a database specialist for international projects. As director she goes above and beyond to create a remarkable retreat experience for guests and retreat producers.
After decades of chasing her own happiness with egoism, hazardous sports, lots of work and not getting anywhere, Ven. Sunam discovered Dharma in 2005 by reading the Diamond Cutter by Geshe Michael Roach. Ever since she has been studying, teaching, and translating ancient texts with joy and happiness, transforming herself into a kinder person. Ven. Sunam has studied all 18 ACI Courses and 11 DCI Seminars, has attended nearly all LAM RIM Retreats and several Translator Terms. She is a certified ACI Senior teacher, and a certified Sivananda yoga teacher.
She fell in love with Diamond Mountain and the desert during her first visit in 2014 and has the passion to preserve the silence, nature, and magic of this exceptional place while transforming it into “the retreat” place for modern time.
How Karma and the Buddhist Principles have helped her:
Through applying the principles in my life: become a much happier person, be able to work part time in a management position, time & money to travel the world to attend teachings, having deeper fulfilling relationships with people, a loving relationship with my family esp. my mother after decades of tension.
LUKE ZERKLE
LUKE ZERKLEMaintenance Manager
Luke, a.k.a. ‘Master Luke’, has multiple trade skills coupled with the patience and dedication for problem-solving that are worthy of a true Jedi. As the youngest of 15 children growing up in a hard-working family of mechanics, welders, roofers, builders and backyard inventors, he naturally learned and assimilated many of these skills at a very early age.
Luke is a California native whose family moved to the quiet town of Bowie, Arizona in the late 80s. During a two-year stint in Las Vegas he worked at his brother’s successful roofing company, learning the trade and eventually becoming a foreman with his own work crew. Upon returning to Arizona in the late 90s, he met his life partner, Kaia. During the course of building their homestead in Bowie, he discovered the world of solar power and a talent for woodwork.
His sought-after skills led him to a relationship with Diamond Mountain Retreat Center in the early 2000s where he took part in many of the building projects leading up to the three-year retreat in 2010. He masterfully crafted the beautiful mesquite doors and windows in the intriguing Blue Sky dome. He felt an immediate sense of kindredness to the place and the people.
In 2019 he took on the position of facilities manager. Luke’s patience, compassion, love of nature, the pursuit of spiritual growth, and talent in multiple trades make him a perfect fit for the job. His mission at Diamond Mountain Retreat Center is to maintain a beautiful and comfortable environment for people to relax and enjoy their retreat experience.
Katie Olsen Featherman
Guest Service Manager
Katie loves learning new things and exploring new places. Born, raised and educated in Arizona she is passionate about being outdoors and has an adventurous spirit. You might find her four-wheeling in the desert, swimming at the local rivers and lakes or camping. She also likes to paint and play golf.
She has worked in customer service-banking, as a store manager for Family Dollar store, and cared for elderly and developmentally challenged adults. Her naturally caring nature also extends to animals and pets. Katie strikes the perfect balance between empathy and caring while also being very organised!
The old adage “find a job you love and you will never work a day in your life” sums up how she feels about being at Diamond Mountain. Diamond Mountain is the perfect opportunity for her to meet people from all over the world and learn about their different cultures and ideas. It also provides the much needed silence we all seek from time to time.

She is passionate about dismantling hierarchical systems and helping individuals step into heart-centered leadership that prioritizes wellness, collaboration, and responsibility.
Her journey with Dharma deepened through study of meditation, yoga, and sacred texts, and has been profoundly shaped by her time at Diamond Mountain.

How Understanding Karma and the Buddhist Principles has helped her:
Applying Buddhist principles has allowed Dee to release old identities, embrace cycles of change with peace, and align her life with service. The four steps and compassion have transformed fear into faith, helped restore balance in relationships, and opened the door to a life of freedom, creativity, and joy; one that uplifts both herself and others.
JOHN DUTCHMAN
JOHN DUTCHMANVolunteer Maintenance & Caretaker
John feels responsible for all the things you might never notice at Diamond Mountain. He works behind the scenes to make every interaction a five-star experience for visitors when they are here. He likes to figure out tricky puzzles, loves efficiency, and being useful. If you want something done, ask him and be delighted that a short while later, it’s done.
His experience working at Taco Bell, Toyota, in the Army, warehousing, compressed gas industry, and CNC machining, gives him the broad range of experience that makes him ideal for working on the Diamond Mountain maintenance crew where there are myriad of challenges coming at you and you have to figure it out.
He likes the challenge of making eggs for large crowds, is an amateur photographer, and has an eclectic and ever-growing music collection. And, if you see him doing the dishes, leave him to it.
How Understanding Karma and the Buddhist Principles has helped him:
Serving by being useful and applying the Dharma to everyday life is what matters most to him despite completing the ACI courses and studying the Three Principle Paths. You will often hear him asks ‘to what end?’, causing you to pause and reflect. When asked about his greatest accomplishments he says: “If I died right now, I can say I stopped killing bugs intentionally”
