Carl J. Bonnett, MD
Founder / Chief Medical Officer
Dr. Carl J. Bonnett is the founder and Chief Medical Doctor at Klarisana. As a twenty-year veteran of the Army National Guard, Carl saw ketamine therapy as a valuable way to help others in mental and physical distress. His vision of love and compassion gave shape and form to Klarisana, one of the country’s first-ever ketamine clinics, whose purpose is to serve all people who struggle with mental illness and chronic pain regardless of their background or any other discriminating factor.
Amber Carrion
Director of Clinic Operations

I am dedicated to pioneering mental health care through our innovative ketamine treatments. With a profound passion for mental wellness, I prioritize cultivating a supportive environment for both our team and our patients. Committed to excellence and compassionate care, I am honored to serve in this transformative field.

Courtney Szigetvari
Director of Behavioral Health
LCSW-S
As an LCSW-S, I specialize in working with complex trauma, dissociation, and psychedelic-assisted therapy and integration. I work from a social justice lens and have an understanding of issues related to racism, xenophobia, classism, heterosexism, transphobia, religious prejudice, ageism, ableism, and fatphobia.

I use the following modalities in the work I do with clients: Internal Family Systems (IFS), EMDR, Somatic Experiencing, Play Therapy, Interpersonal Neurobiology, psychoanalysis, Psychodynamic Therapy, Gestalt Therapy, family therapy, feminist therapy, humanistic therapy, CBT, DBT, Narrative Therapy, and Motivational Interviewing. I am IFS Level 2 trained and EMDR trained. Further, I am MAPS trained in MDMA-assisted therapy.
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.
Jodie Clark
Behavioral Health Provider
LCSW

Jodie Clark, LSW, is dedicated to enhancing the well-being of individuals across various healthcare settings. With experience at various community and rehabilitation clinics, Jodie has an array of experience in coordinating care, crisis intervention, and therapeutic counseling. Specializing in person-centered care for patients at Klarisana, Jodie loves using a wide range of therapeutic interventions including animal-assisted therapy, music, art, and aromatherapy.

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.

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.
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.
Candace Sneed
Medical Provider

Candace is a board-certified Nurse Practitioner with a strong background in primary care and a deep passion for mental health and holistic healing. With experience in family medicine, Candace has provided compassionate, patient-centered care to individuals across all stages of life. Through this work, she developed a profound understanding of the interconnectedness of physical and mental health, fueling a desire to explore innovative treatments for mental wellness.

Candace is committed to guiding patients toward relief and profound transformation through psychedelic medicine. Her approach combines evidence-based practice with a holistic mindset, ensuring that each patient receives personalized care tailored to their unique healing journey. She recognizes ketamine not only as a powerful medical treatment but also as a gateway to deep emotional healing and self-discovery.

Beyond the clinical setting, Candace is an advocate for the responsible integration of psychedelics into mental health care and is committed to ongoing education in the field. In her  personal life, she finds peace and inspiration in nature, often hiking and immersing herself in the outdoors as a form of personal renewal. With a holistic and heart-centered approach, Candace strives to help patients rediscover hope, healing, and a greater sense of well-being.

Rachel Lee
Medical Provider
With a deep passion for mental health and alternative medicine, Rachel brings a unique background to the team. She spent eight years as a traveling nurse across five states before earning her master’s degree as a Family Nurse Practitioner and settling in Colorado. Inspired by the potential of integrative medicine, she spent her first year of practice providing non-narcotic pain management and wellness-centered care before joining Klarisana and transitioning her focus to mental health.
 

Rachel is dedicated to helping patients find relief physically, mentally and spiritually, offering compassionate and evidence-based care. An adventurer at heart, she has hiked all 58 of Colorado’s 14ers and, in 2017, spent six months walking from Mexico to Canada on the Pacific Crest Trail. She brings this same resilience and dedication to her practice, supporting patients on their journey toward healing and well-being. 

Jennifer Curtis
Medical Provider
I completed my master’s in nursing from the University of Arizona, specializing in family medicine. I have previously worked in primary care before switching into the mental health field. I started with Klarisana in 2018 and I have a passion for working with psychedelic medicine. My goal is to provide higher quality mental healthcare by working with highly effective ketamine treatments. My mission is to create a safe space for healing, growth and wellbeing. When I am not working, I enjoy gardening, being in nature, traveling and spending time with family and friends.
Danielle Cole
Medical Provider

I am a board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC) dedicated to helping individuals feel heard, supported, and empowered in their mental health journey.

I specialize in treating anxiety, depression, PTSD, trauma, and mood disorders, and I understand how overwhelming it can feel to take the first step toward healing. My goal is to create a safe, nonjudgmental space where we can collaborate on a treatment plan that feels right for you.

My background includes both critical care and psychiatric nursing, including frontline experience as an ICU nurse during the COVID-19 pandemic—an experience that deepened my compassion and commitment to mental health care. I incorporate evidence-based approaches and innovative treatments like ketamine-assisted therapy for individuals navigating treatment-resistant conditions, always tailoring care to meet your unique needs and goals.

Outside of work, I enjoy fitness, traveling, interior design, thrifting, and spending time outdoors. I’m also currently learning to play golf! I strive to bring the same sense of curiosity, balance, and creativity into my clinical practice as I do in my personal life.

If you’re looking for a supportive provider who will truly listen and walk alongside you in your healing, I’d be honored to be part of your care.

Mary Ann F. Apopot
Nurse Practitioner
MSN, APRN, FNP-BC, CCNS

I am a board-certified Family Nurse Practitioner and Clinical Nurse Specialist with over 30 years of diverse experience across hospitalist medicine, nephrology, intensive care, home health, rehabilitation, and nursing education. Throughout my career, I’ve developed a strong foundation in managing complex medical conditions and providing compassionate, patient-centered care.

My clinical approach is patient-centered and trauma-informed, with a focus on compassionate care, emotional safety, and long-term wellness. I’m excited to bring this perspective to Klarisana and to be part of a forward-thinking team that prioritizes innovative solutions for mental health and treatment-resistant conditions.

My goal is to contribute meaningfully to the healing journey of every client we serve—while also continuing to learn, grow, and collaborate with the talented team at Klarisana.
