Ven. Sunam | Director
VEN SUNAM HLAMO, Dr. Brigitte Mayr


“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.



Hanlie’s fascination with human behavior started while growing up in South Africa. An adventure seeker and serial entrepreneur she started her first of several businesses at the age of 23 followed by a career that spans three decades and four continents.

As a social scientist she was inspired by Nelson Mandela who said: “People must learn to hate, and if they can learn to hate, they can be taught to love”. This quote also formed the basis of her Ph.D.  In the last decade, her focus was on behaviorally designing the world of work to humanize workplaces by creating a culture of tolerance and connectivity.

She started meditating and doing spiritual retreats in the early 2000s. A friend introduced her to Asian Classics Institute courses where she received teachings from Geshe Michael Roach, Lama David Stumpf, and Lama Marut.  She taught herself yoga from The Tibetan Book of Yoga, expanded her repertoire to Ashtanga, Inyengar, and Bikram only to find her way back to the yoga of Lady Niguma. A trip to the temples of Thailand forever changed her life. After moving to the US she found her Sangha in Chicago.

Hanlie took the long road to get to Diamond Mountain. She was the last volunteer to arrive before the COVID-19 lockdown and the instant she set foot on the property she knew she was not going to leave in any hurry. She served as Co-Director during COVID and is now coordinating the Stupa project.

How Understanding Karma and the Buddhist Principles has helped her:

For me, the value lies in applying the principles to every encounter, situation, and interaction. As a closet nerd, I strive at all times to bridge the gap between principles, theory, and practice. The result is equanimity, perpetual learning, and loads of fun!


Maintenance 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.


Spiritual Caretaker

Never believe that a few caring people can’t change the world. For, indeed, that’s all who ever have.” -Margaret Meade

Spending part of her childhood in Africa instilled in her a deep appreciation for beauty and simplicity. Kat attended school at Nairobi International School, played violin professionally, studied with British Riding Academy and Ethnomusicology at UCSC.

Passion and belief in successful evolution for humankind drive Kat. During her early twenties, Kat worked for the president of a fast-growing start-up fulfilling multi-national contracts with royalty and governments. This extraordinary experience implanted the confidence in her that any problem can be solved while having lots of fun. For the next 30+ years, she launched successful start-ups in catering, film, fine art publishing, a school, a newspaper, and developing products benefiting rural communities globally.  With two pre-school sons, Kat moved to the wilderness in Southeast Arizona where she built their homes.

In 2002 in the same wilderness, she met Geshe Michael, and life changed.  She gave away businesses, sold land, and moved to Diamond Mountain. For the next nine years, she helped build and operate the first buildings on the land as a volunteer. In her exuberance, she also completed advanced coursework; finished a 3-year retreat; became an ordained nun; worked for the Asian Classics Institute;  and helped launch the Sedona College of International Management in Arizona.

Now joyfully back at Diamond Mountain, Kat serves as caretaker for retreaters and ceremonies, continues studying and volunteering for world-view groups.

How Understanding Karma and the Buddhist Principles has helped her:

Using the four steps and the four powers has given me a logically-proven way to tailor-make my life. It’s been super-fun to practice and watch relationships shift, beautiful homes appear, health restored and wisdom spread, with happiness and freedom in others around me, too.

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.


Volunteer 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”


Steward & Volunteer

Joe has an engineering technology degree and worked in engineering for 30 years. He is also a veteran of the army and navy. Most importantly… he is a grandfather of 9!

In 2002 he came across Geshe Michael on the internet and followed his teachings until 2009. When he retired early at 57, he drove out to see Diamond Mountain in person where he worked with a lot very cool people building the retreat valley.

After volunteering at Diamond Mountain for two years he remembered he had a guitar at home in Wisconsin. The next time he came back he brought it along and has been entertaining us and working on his guitar skills ever since.

Joe loves the land is beautiful sparse that goes for miles and we love his calm, grounded energy and sense of humor.

He works with our maintenance team and takes care of our gnarly roads.
