Mano Jayasekaran, AMFT
Therapist

Healing starts the moment we feel seen, heard and known. I believe that healing and wholeness within one self can bring about healing and wholeness in our interpersonal relationships. I therefore incorporate an integrative, strength-based approach in my practice. As an immigrant of Indian origin, I can deeply empathize with those who struggle with acculturation stress, sense of identity and belongingness.

As a licensed Associate Marriage and Family Therapist, I employ an eclectic method to help clients understand the underlying reasons for their distress, identify negative thought patterns which may contribute to challenging behavioral patterns, like anxiety, depression, etc. Whether feeling stuck or overwhelmed by sudden transitions in life, or struggling to navigate complex relationships as an individual, couple or as a family, I consider it a privilege to walk alongside my clients, as they courageously navigate difficult seasons of their life.

Within the safety of a trusting, respectful and supportive therapeutic environment, I collaborate with clients to explore practical steps which will help them in their journey towards flourishing. Nothing gives me greater joy than to see my clients become the best version of themselves.

I earned my Master of Arts in Family Life Education from Martin Luther university and Master of Sciences in Marriage and Family Therapy from Fuller Theological Seminary, School of Psychology. I enjoy cooking, painting, and spending time with family and friends.

Renew & Revive Spiritual Group Sign Up

This Renew & Revive (R&R) group is a program established by the team at Fully Health to provide a comprehensive approach to address all our needs – physical, mental, and spiritual. Through attending these complimentary group sessions, you will learn about the good news of Jesus Christ and how God will intervene during our journey toward achieving healing and greatest potential.

All individuals 18+ are welcome to attend! You do not need to be a Fully Health client or patient to attend. This service is free of charge. Please note, these sessions are not a clinical service. You may come and go as you like. We would be happy to have you whenever you may be available to join!

Wednesdays 7:30 – 8:30 pm on Zoom

What to expect from R&R
– To deeply understand, believe, and enjoy the Gospel, and know who I am
– To be able to have any question answered without judgment. For example, “Why am I struggling so much even though I have faith?” and “If I seek psychiatric treatment, does that mean my faith is small?”
– To experience the ability to fight the spiritual battle in life, especially regarding mental health struggles around me
– If Jesus is the Christ who solved my fundamental spiritual problem that led to all the “bad fruits” of life, then He is the answer to any other problem (mental and/or physical) that I may face on this earth.
