Absolutely amazing woman! Very excited and grateful to be able to work with her. I've been in and out of therapy my entire life and she is truly the best that I've had the pleasure to bare my soul to. Each time you meet, you'll feel like the those struggles you've been having may not actually be so big and intimidating. Very upbeat and connects through knowledge and personal experience. She's not talking from a text book, but definitely knows what she is talking about. If you are fortunate enough to be able to book her, quit reading this and go do it!!! I promise you won't be disappointed. I'm blessed to have her.

I have been searching for a psychologist like Dr. Kathryn Cornella for a long time, and I am incredibly grateful to have found her. In just nine sessions, Dr. Cornella has demonstrated an exceptional ability to quickly understand me and thoughtfully redirect my thinking in ways that have led to meaningful, positive changes in my life.
I began working with her during an acute flare of my autoimmune condition, a time when my mental symptoms were particularly debilitating. During this period, Dr. Cornella provided steady, compassionate guidance and helped me navigate heightened anxiety-especially work-related stress that I am typically able to manage on my own. Her support during this challenging time made a significant difference.
Dr. Cornella is caring, intelligent, and pragmatic, and she brings a rare balance of empathy and actionable insight to her work. BetterHelp is fortunate to have a psychologist of her caliber on its platform. I look forward to continuing my work with Dr. Cornella for many years to come as I continue learning how to live well with my autoimmune condition.

Dr. Cornella listened with compassion, understood where I was coming from, and asked insightful questions that encouraged and challenged me. She was both affirming and practical, offering solutions that addressed my situation. She has broad expertise in everything from family matters to work and health, and I feel like I can talk to her about anything!

Dr. Cornella is so intelligent and insightful and she challenges me to go deeper- where other therapists have let me “get away” with deflecting with humor or sharing a surface level observation of myself to avoid getting into the hard stuff. She seems to know where we need to go better than I do. I’m extremely grateful to have found her.
