Alli first discovered yoga in college when she began taking classes to relieve stress and to improve focus. It wasn’t long before she became aware of the physical, emotional, and spiritual transformations that were taking place and became inspired to share the practice with others. She completed her yoga teacher training in Koh Samui, Thailand in 2015 and has since had the pleasure of helping others learn how to cultivate a sense of tranquility and balance in their everyday lives. Her intention is to make the practice of yoga welcoming, accessible, and supportive for all of her students.

Alli recently moved to the valley from the Chicagoland area and likes to spend her time gardening, hiking, learning, and sipping herbal teas. As a long-time climber and retired skydiver, she understands the importance of daily movement and mindfulness and is excited to be a part of the Alta community!


Hello Yogis! I’ve been practicing and teaching yoga for over 20 years. I first fell in love with yoga while attending massage therapy school and added a 200 hour teacher training course. As a veteran of the Marine Corps I was drawn to help those with post traumatic stress and obtained my 500 hour certification in Healing Emphasis Yoga which focuses on healing both the mind and body cohesively.  I encourage all yoga/stretching enthusiasts to attend my class regardless of ability and will make sure everyone is welcomed and challenged to their desired level.

Yoga is allowing me to give back and make a difference for those that need it most and I sincerely appreciate your presence for allowing me to do so. If I have any “downtime” it consists of herding the various animals on our hobby farm including a horse, goats, pig, turkeys, ducks, countless chickens, a cat, a bunny, a cockatiel, husband, and two human boys.


I have been practicing yoga for nearly 10 years. I completed my YTT with Core Power in 2015 and will finish my 500 hour RYT in 2022. I thrive well in Vinyasa, hatha, and yin yoga. I enjoy being active trying to keep up with my two toddlers and fur babies. My favorite hobbies are kayaking, SUP, hiking, trail running, climbing, and of course yoga.

Yoga Teacher & Therapist, Barre & Pilates Instructor

I love to help people find their capabilities while having fun in their Yoga practice! Along my journey with teaching and practicing I also became a Pilates and Barre instructor which adds to the variety in my classes. My teaching encourages a strong foundation, building strength in poses, and intentional movement, thoughts, and breath. As a licensed Yoga Therapist (think holistic Physical Therapist/Yoga teacher) I encourage focus on movement and breathing to tone and strengthen the parasympathetic nervous system, the nervous system responsible for digestion among other things. I encourage people to show up, listen to their body, and experience the natural growth that comes with practicing Yoga on and off the mat, approaching your practice with curiosity, patience, and playfulness, all which will to lead you to your inner peace, truth, and joy that is your natural state. I feel so lucky to be able to help people feel their best, can’t wait to see you in class!


After several years of practicing law, I began to feel stressed, run down and overwhelmed. At the recommendation of a friend, I decided to try yoga. I fell in love with the practice after my very first class. I was so inspired by all the benefits yoga provided, that I decided to bring this gift to others. I received my 200 hour certification in 2010 and my 500 hour certification in 2016. My hope is to inspire my students to progress on their own personal journeys while experiencing all that yoga has to offer on and off the mat.

When I’m not teaching or practicing yoga, you’ll find me rock climbing, hiking, or lounging by the pool. I’m excited to be part of the Alta community and look forward to sharing my practice with you!


Kari began practicing yoga 6 years ago to help heal her body from years of sports injuries and health issues. After experiencing positive changes, Kari felt drawn to certify and help others find healing in their minds and bodies by using their breath in various types of yoga. Her main goal of every class is to have students leave happier and healthier than when they came.  When not teaching yoga, you can find Kari cheering her 5 kids on in soccer, football, swim and running events or adventuring somewhere awesome with her husband. Kari began climbing in her youth with her brothers and enjoyed competing in indoor speed climbing and bouldering contests through college. She won free gear but mostly had a blast pretending to be spiderman.


Nearly 10 years ago, Marissa graduated with a 200-Hour Hatha Yoga Teacher Training with a specialization in alignment, yogic philosophy, and meditation. Over the last decade, Marissa has taught for thousands of hours in traditional class settings, hosted multiple international yoga retreats, and trained dozens of teachers as an E-RYT 200 Lead Yoga Teacher Trainer.

Discovering the practice of yoga was one of the most profound moments of Marissa’s life. It was through a dedicated yoga practice that Marissa found confidence in and love for herself. The impact that yoga had on her life quickly led Marissa to become a teacher herself so that she could share this incredible practice with others. Still enamored with the effects yoga has on herself and others today, Marissa’s affinity for the practice can be felt in all her classes.

Students of Marissa describe her classes as an experience that transcends the physical experience of yoga poses and taps people into the deeper parts of themselves. With Marissa, no two classes will ever be the same. Marissa uses her passion for and knowledge of the human body to focus on one pose and dissect it in a curious, fun, and mindful environment. As Marissa guides students in and out of poses via descriptive and creative cues that encourage students to travel towards the edge of discomfort, she brings students completely into the present with a continuous focus on a yogic philosophy or tradition that equips people to better navigate themselves and their lives both on and off the yoga mat.

As a passionate rock climber, Marissa’s class will not only open and lengthen the parts of the body that get tight from climbing, she’ll also focus on stability, balance, and strength to help climbers send their projects with greater ease.

Marissa’s primary motivation for teaching at Alta is to help build and be a part of an inclusive and accessible community both on and off the mat. Whether you take her classes or not, Marissa will always be a friendly and welcoming face around the gym.

When she’s not moving on her mat or rock climbing in a gym or outside, you can find Marissa playing with her dog, spending time with loved ones, cooking, or doing design work for her primary job.
