What Our Patients Say

Grace H.

"Being in this [integrative program] has helped me realize that I am not alone in my journey and that there are others going through very similar things. I felt loved and included by all…I may be in a rough patch at any given time, it won’t last because God has helped me and will help me stand back on my feet to be my best self. I have less anxiety and fear for my future. I feel much more stable and strong."

Jamie C.

"The gospel partnered with cognitive behavioral therapy and group counseling is key. My therapist and pastors who led the spiritual counseling sessions have been very supportive and see the power of the Gospel. Understanding the power of the Gospel is also very crucial to recovery."

Robert O.

"A lot of times, mental difficulties were seen as “curable” by prayer or seen as lack of faith and discipline by the world. It was good to feel reassured that Christians can struggle with mental health, and to learn how to view it through scripture. I also like that other than my friend group or church community, I have yet another group of people who would be able to pray for me and other people who I could pray for."


What Our Community Says

Kenny Luck

Founder and President of Every Man Ministries

"As a pastor serving in South Orange County for over two decades, I have needed to form partnerships with mental health professionals I can trust to serve our ministry to individuals, couples, and families. Thank God for Dr. Esther Park, Dr. Mijin Park Psy.D. and the team of counseling professionals at Fully Health based in Laguna Hills. It is such a comfort to know that anyone we refer to Fully Health will receive top notch clinical services and help as well as strong support to pursue their faith as a part of the healing process. I am ecstatic to have them as a part of my "team" of elite helpers for those who are hurting and in need of true hope."

Dr. Mariam A. Mott, Ph.D.

Licensed Clinical Psychologist

"I have known and collaborated with Dr. Esther Park for approximately 10 years. She has always impressed me with her knowledge, professionalism, and insight into her clients. I have also worked closely with one of her colleagues, Dr. Mijin Park, who is both a talented clinician and a caring human being. Oak Health Center is my first referral for clients who can benefit from their services because I know they will receive exceptional, caring, individualized treatment from Dr. Park and her Team!"

Fully Health is sponsored by Oak Health Foundation, a nonprofit organization committed to integrating the Gospel message into mental health treatment and reducing the stigma and prevalence of mental health disorders by addressing the whole person – mind, body, and spirit.

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.
