Thoroughly committed to her education – and her offerings – on this path of yoga, Nikki has the patience, presence and evolving understanding I aspire toward in my own work, both internally and externally.
The way in which she articulates her own practice illuminates the potential for confidence and clarity in every pose; and when I have the privilege to teach alongside her, an expansion occurs that reverberates in my heart, and in the hearts of the students, for months to come.

Nikki Costello is a gifted teacher, and someone who, though we are peers, I find myself looking up to again and again for insight and inspiration. As mere “babies” on the Yogic path back at the Jivamukti Yoga School in 1997, Nikki stood out in our teacher training group as someone who was not only deeply committed to this practice, but would uncover every stone in her search for clarity and knowledge. She has continued to do so over many years of practice and teaching, and it shows. Her warmth, joyousness, and compassion as a person are clearly perceived in her teaching, and I am honored to know her! If you have the opportunity to be in a Yoga studio or classroom with Nikki, you should jump at the chance!!

Nikki has helped me to be more flexible outward and more peaceful inward. Yoga has become a necessity for my well being. I owe this awareness to Nikki.

Nikki gave me in one session what felt like a day-long retreat. I felt revitalized and nourished in my body and my mind. Her warmth and love, with which she infuses everything she does come from years of spiritual practice and her generosity of spirit. Having a private session with her is a great gift you can give to yourself!
with love and gratitude,

Nikki Costello is an amazing yoga teacher with vast experience in the US and India. When working with Nikki I find my sessions intense, exacting, challenging and fulfilling. In a surprising way, she becomes like an intuitive, at tune to the particular needs of my body on any given day, either pushing the work to new places or taking it slow and steady and pushing from within. Nikki is a master at her craft, and a session with her is a rare and profound experience.

Thank you sweet Nikki for supporting me in my physical, emotional, and spiritual growth. Your level of understanding the body from a physical and healing standpoint always seems to bring about many aha! moments when working with you. When I take sessions with you I know my body is in the best possible care. You have a very special gift my friend. You’re a treasure chest of invaluable information, and thankfully, you have the gift of being able to articulate your knowledge. I’ll never forget my 4th session with you. You took me to the most beautiful peaceful place I’d ever been before, my heart. Thank you for exposing me to it. With so much love and gratitude.

I love my yoga sessions with Nikki. Her knowledge of the mechanics and spirituality is the perfect blend for a powerful session. As a yoga instructor I gain so much from our time together in my own practice and furthering my teaching skills. Thank you Nikki for always providing me with exactly what I need. My sessions with you are precious.
