Sapna Sareen
Patient Advocate, TMS Treater
Working at Solstice as a patient Advocate has been a full circle moment for me, namely giving back to the patients what I have learned here. My true reward is to see a patient’s transformation from a negative mindset to that of a positive outlook. The way I prioritize my commitment towards patients is through selfcare, mindfulness, keeping things in perspective, making new connections as well as making time for my hobbies and volunteering in my community.
I have learned through my mental health journey how important family connections are in a patient's recovery. Family members provide happiness, security, support and a sense of purpose and that’s why patients and their families come first. I have a Master’s degree in Molecular Biology and I have worked in the field of scientific Research and Development for many years.
Every adversity in my life has taught me that I can not control the circumstances around me but I can control my thought, action and my behavior towards it. I continue to learn and grow everyday and I am grateful for what I have.
