Tatyana, daughter of Dale, helped to found Serene Spirit Mental Health Care when it opened in 2016. She has a Bachelor of Arts in psychology and vocal performance from Luther College. 

Since opening Serene Spirit, Tatyana has learned a great deal about how mental health impacts the ins and outs of our daily lives and how it can manifest into our relationship with our own self. She believes that open and honest communication about our own struggles combined with education on the effects of societal and familial pressures allows the veil between professional and client to be lifted. 

Serene Spirit was cultivated with staff AND patient health in mind. Tatyana believes the voices that matter most are the ones that have been hidden for far too long and strives to bring back those voices so we can have the ability to see each other as we are - human. 

At this time, Tatyana will continue to assist with billing and insurance questions you may have to confirm that your care is being covered. Stay tuned for more updates as the progress of Serene Spirit continues to grow and bring positive changes to Rochester, MN and surrounding areas.
