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 PhD.  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 2000’s. 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 is on a mission to create a retreat center where guests can find their spiritual oasis in the desert and leave feeling spiritually reconnected, mentally rejuvenated and physically restored.

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, 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.


Hospitality Manager

Nicole is a creative soul that has a passion for designing beautiful spaces, cooking delicious healthy meals, and teaching yoga. 

She studied at the New York School of Interior Design, Parsons New School, and the Laboratory Institute of Merchandising and applied her skills in the interior design and fashion industries.  Soon after she decided to pursue her fascination with flavor at the French Culinary Institute and worked as a private chef and food stylist in NYC.  She discovered the magical power of yoga while at a Three Jewels silent retreat in Nicaragua and shortly after escaped to India where she studied yoga on the beaches of south Goa.   

In 2011 while living on the Upper East Side in New York her friend invited her to a Buddhist teaching at Pure Yoga, a few blocks away from her apartment.  Intrigued but not having any expectations she was blown away by Geshe Michael’s teachings on emptiness.  Everything for the first time made perfect sense to her and she has been studying ever since. 

In March 2019 she came to volunteer for the Lam Rim retreat at Diamond Mountain.  Falling in love with being surrounded by the dharma all day every day, she joined the team.  Nicole is the hospitality manager and private chef at Diamond Mountain Retreat center. Working with our sister organization, the Yoga Studies Institute, her knowledge of yoga philosophy and asana classes keeps staff, volunteers and retreatants healthy and balanced. 

She is on a mission to create the perfect retreat experience for all our guests and volunteers. 

How Understanding Karma and the Buddhist Principles has helped her: 

I have been able to transform the way I look at life and deal with everyday situations. I am surpassing my dreams and creating new and bigger dreams in a skillful way.

He is famous for asking  so many questions on a trip to India that Geshe Michael still tells the story about him winning a debate with a Geshe. 

In 2019 Juan came to volunteer at Diamond Mountain and shortly after decided to stay and become part of the team. Juan Jasso is our Lower Campus Manager where his entrepreneurial flair and willingness to learn comes in very handy.  He is kind, patient, always willing to listen and teaches meditation. 

How Understanding Karma and the Buddhist Principles has helped him:

That working with karma and emptiness anything is possible... even stopping baldness and finding love in the middle of the desert.



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 developmening 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.
