I cannot recommend my counselor highly enough. From the very beginning, John created a welcoming, supportive, and judgment-free environment where I felt comfortable being open and honest. His insight, compassion, and ability to listen have helped me navigate challenges, gain perspective, and grow in ways I never expected.

What stood out most was genuine care and dedication. He took the time to understand my concerns, provide thoughtful guidance, and equip me with practical tools that I can use in everyday life. I always left my sessions feeling heard, encouraged, and better prepared to move forward.

If you're looking for a counselor who is professional, knowledgeable, compassionate, and truly invested in helping people succeed, I highly recommend John Kilgo.

Olive Tree Counseling has been a true lifeline for me. I first came to them while grieving the loss of my mom to COVID, and they helped me navigate a level of pain and confusion I didn’t know how to face on my own. They created a space where I felt safe, understood, and supported through every step of that healing process.

They also walked with me through another huge chapter of my life — finding my birth parents and learning how to build and manage those new relationships. Their guidance helped me stay grounded, honest, and emotionally steady during something that could have easily felt overwhelming.

On top of that, they’ve supported me through unexpected life changes, giving me tools to cope, adjust, and move forward with clarity. Every session left me feeling lighter, stronger, and more capable.

I would absolutely return for more counseling sessions. Olive Tree Counseling is compassionate, professional, and genuinely invested in your growth and wellbeing. I’m deeply grateful for the impact they’ve had on my life.

John is a great counselor/listener. He has helped me through many things. I believe he tailors his consultation to each individual's personality. For example, for me I wanted someone who would help me with identifying weaknesses and traits I need to work on, he was excellent at that. He would listen, then ask questions that, when I go home, I think about deeply. Without his guidance, I would have been stuck in many situations that I needed to overcome.

John is simply the best!  He has a gentle spirit and that helped me to trust him with the difficult problems I needed to work through.  He helped me to understand my needs (he even emailed me a sheet of needs).  It helped me understand how to prioritize them, and how to voice them in my relationship without sounding demanding and threatening.  Our last session (for now) was a banner day.  I called for an appointment to share a revelation about a situation that had caused great hurt to my heart.
I could truly go on and on about John, but if you need a professional and caring counselor call him he is simply the best!!!

Amazing practice! Found John Kilgo while searching for Christian marriage counselors in the area. Can’t recommend him enough, my husband and I really enjoyed talking through different things with him, he offered such simple and practical suggestions that made a world of difference to us as individuals and in our marriage. He also does an amazing job of weaving faith and biblical principals into the conversation!

Meet John Kilgo, M.S., LPC

As a Licensed Professional Counselor and founder of Olive Tree Counseling, I’ve spent years helping individuals and couples navigate anxiety, depression, grief, and relationship challenges. I draw from evidence-based approaches including the Gottman Method, EFT, CBT, and Internal Family Systems — meeting each person where they are.

Trained at Wofford College and Walden University, I worked with the Greenville Mental Health Center for nearly a decade before founding Olive Tree, where I’ve worked with hundreds of clients across the Upstate of South Carolina.
