Carolyn Gubelin
Clinical Manager,
Medical Provider
I completed my bachelor’s in nursing at the University of Oklahoma (Boomer Sooner), and my master’s with Frontier Nursing University in Kentucky. My experience prior to Klarisana mostly took place in the hospital- on the cardiac, transplant, and orthopedic units. My top priorities for my practice are safety and integrity, I want patients to feel cared for and feel trust in this clinic and our process. I have a passion for this type of medicine, and a lot of this is due to the outcomes in our patients and the amazing transformations I have been able to witness.

When I am not working I enjoy walking my senior dog, being out in nature, and spending time with my friends, family, and partner.
Trista Charnas
Behavioral Health Provider
LPC
Trista Charnas is a licensed professional counselor with a background in case management and counseling children, adolescents and families. Her experience in play therapy has translated nicely into the world of psychedelic medicine allowing her to comfortably work with the abstract and unordinary. Trista works from a strength based and solution focused approach meeting her patients where they’re at and always with unconditional positive regard. Trista prides herself on making therapy feel like you’re talking to an old friend and encourages you to kick off your shoes and get cozy on her couch; therapy can be difficult enough, why not get comfy? When she’s not working Trista enjoys watching her son play soccer, taking naps whenever possible, and watching Purdue basketball.
Abbey Foels
Medical Provider
I completed my master’s in nursing from Georgetown University, specializing in Women’s Health.

I have experience in a variety of clinical settings, such as outpatient mental health clinics, outpatient women’s health clinics, in-home care through home births, Colorado state prisons, and in Colorado’s education system.

My goal is to cultivate a safe space for individuals to tap into their most authentic selves to optimize growth and healing. I have a passion for working with our LGBTQ+ community and with psychedelic medicines. My hope is to always honor plant medicines and keep their culture and history alive. I have my 200 hour yoga training and incorporate mindfulness, breathwork, meditation and intention setting into my professional and personal life.

When I am not working I enjoy outdoor activities such as skiing, hiking, being by a body of water and enjoying any form of live music.

Lindsay Hill
Medical Provider
I’m Lindsay Hill, FNP-C, a board-certified Family Nurse Practitioner based in Colorado, advocating holistic healthcare.

I champion equity, particularly in underserved communities, ensuring access to high-quality care. I’m passionate about the intricate link between mental and physical health, advocating positive affirmations and gratitude practices. Beyond the clinic, I volunteer with adults with developmental disabilities and support human empowerment nonprofits. I promote responsible psychedelic research through education and harm reduction efforts, fostering a safe environment for exploration and healing. Nature is my solace; I enjoy paddleboarding, hiking, skiing, and Pilates. I find inspiration in art, music, and cherished moments with loved ones.
Briana Spires

Briana graduated with a Masters Degree from The University of Oklahoma’s Physician Assistant program in 2013, after studying Psychology at Oklahoma State University.  After practicing as a surgical PA for 8 years, she began to reignite her interest in psychology after seeing her own family struggle to find true or complete benefit from traditional mental health treatments.

Briana completed a Psycho-Spiritual Integration certificate along with a Nutrition for Mental Health course from Being True to You in 2022.  She subsequently enrolled in Naropa University’s Psychedelic Assisted Therapies Graduate Certificate program, graduating in December of 2022.  Included in Naropa’s program was also training from the Multidisciplinary Association for Psychedelic Studies (MAPS) in MDMA-Assisted Psychotherapy.  Briana continually deepens her knowledge via training courses and conferences year-round.

Briana followed a calling to return to her True self, and also guides patients to return to Self through the wisdom of their Inner Healing Intelligence. She also acknowledges with respect the Indigenous Wisdom that has been shared from generations of healers. 

Briana believes daily life should contribute to wellness –  valuing health, nutrition and lifestyle.  Psychedelic experiences (and other life changing experiences) can be integrated into daily life in a way that we remain grounded while simultaneously connected to our Higher Self.

Shannon Andrews, LPC
Behavioral Health Provider

I received my Bachelor of Arts in Social Work from Colorado State University, and my Master of Arts in Clinical Mental Health Counseling from Regis University.

Throughout my career, I have worked in various settings such as community service organizations, private practice, and a psychiatric hospital. I also spent 3 years in England working for social services, which offered me significant professional and personal experience.

My role at Klarisana has been my greatest honor. Working with psychedelic medicine is unique and awe-inspiring. I aim to provide a welcoming, safe space where you can fully be yourself. I believe we all have the capacity to grow, learn, and change, and have innate strengths to draw upon. I take a person-centered approach that considers your needs and personality, while incorporating evidence-based modalities such as Eye Movement Desensitization and Reprocessing (EMDR), Acceptance and Commitment Therapy (ACT), and strength-based therapy. Wherever you are in your journey, I would be honored to be alongside you.

My personal interests include my love of being a mom, quality time with family and friends, puzzles, documentaries, and stand-up comedy.

Makayla Hesseltine
Nurse Practitioner

Current Ketamine Therapy Medical Provider and Hospitalist Nurse Practitioner. Retired ICU RN of 9 years.

I have personally lived through a traumatic injury and other major life changes which turned out to be a blessing professionally, as I have truly learned first-hand the challenges and needs of a patient.  I also worked diligently as a bedside ICU nurse during the height of the COVID-19 pandemic.  My unique personal and professional healthcare experiences give me a level of motivation, maturity, and compassion that distinguishes me from other providers.

I am a Colorado Native and love spending time in the mountains. Work-life balance is important to me, when I’m not working, I enjoy off-roading in my Jeep, hiking, paddle-boarding, swimming, reading, and going on adventures with my three sweet dogs who are my kids.

Arlene Pace
Behavioral Health Provider
LCSW
My name is Arlene. I identify as Queer/Non-Binary and I am a Licensed Social Worker.

I am intensely passionate about trauma informed healing modalities and social justice.

I’m currently geeking out about ant farms and ant species/colonies in my spare time. I love to dance, thrift, be outside and be goofy with my friends. A weird fact about me is that I was born in the Outback of Australia. Oh and I love collecting miniature alligators and horse trinkets
Jeanine Snyder
Medical Provider
I am a Family Nurse Practitioner who started my career in Exercise Physiology before pursuing a nursing degree. I obtained a BSN from Regis University in 2012 and after nearly a decade of critical care and post-surgical care, I returned to school to become a Nurse Practitioner. My passion is to not only save lives but to increase the quality of life by having a collaborative approach with my patients. I believe that we are a team- I may have medical expertise, however, you are the expert of your own body so together we will work to improve your life.

My journey to psychedelic medicine was a personal one. After working through the pandemic as a front line nurse, there were several colleagues of mine who struggled with their mental health. One of my them found Klarisana and she expressed to me how significant this treatment was to saving her life. Now that I have been working closely with this team for almost two years, I can see why she overcame her depression. I feel very lucky to be a part of a culture committed to compassion, authenticity, and patient-focused care.

When I am not working, I enjoy spending time with my family, playing fetch with our four dogs, learning a new sport to play, and re-watching the Office.
Hannah Gunnison
Medical Provider
I am a family nurse practitioner with 10 years of experience in the healthcare field. I am passionate about mental health and holistic wellness and I am currently completing a program in functional/holistic medicine. I believe in working with patients to find the root cause of their symptoms in order to help them fully heal. I believe that psychedelic medicine can be a gateway to help patients address the root cause of their mental health struggles in a way that other therapies are not able. It has been a privilege to work in the psychedelic medicine space and to witness the healing transformations of so many patients. I strive to make a meaningful difference in the lives of my patients, and in the clinic I hope to serve as a beacon of hope, supporting my patients on their healing journey. I am a Kansas City native and recently moved to Colorado. Outside of work I like to spend as much time as possible outdoors, exploring the beauty that Colorado has to offer.
Erica Henston
Behavioral Health Provider
I originally graduated with a Bachelor of Arts in communication and art history from Denison University in 2008. After some searching, I learned my passion was in helping others. I have been an emergency room nurse for over 11 years. Working in emergency has given me the opportunity to work with diverse groups of people and situations. My passion for alternative medicine developed years ago when I felt there was a disconnect in treating the diagnosis, but not the person. I graduated with my master’s in nursing with a specialty in psychiatry from Saint Louis University and have a certificate degree in alternative and integrative medicine from the University of Colorado. I love being a bedside nurse, but I am ready to take my knowledge and dive into what I believe to be the future of psychiatric medicine. As a PMHNP I hope to work with each individual and collaborate on the best treatment plan to enhance well-being.
Samantha Stern
Medical Provider
I graduated from Pacific University in 2017 and bring 7 years of experience and a passion for mental health to my role at Klarisana. I began my career in Lake Tahoe working in primary care before my interest in mental health led me to move to Maine and specialize in addiction medicine and psychiatric care. I later moved to Denver and joined the Klarisana team in 2023, marking a new chapter in my career. I am excited about the opportunity to practice in the field of alternative mental health treatment. I believe deeply in the power of alternative mental health treatments and am dedicated to offering my patients the most effective care options available, contributing significantly to their recovery and well-being. Outside of my professional life, I am an avid explorer who enjoys international travel, snowboarding, and discovering all that Colorado has to offer.
