With over 20 years of healthcare experience, I have dedicated my life to helping others achieve mental wellness. I understand how mental health impacts all areas of life—personal, professional, emotional, and physical well-being. Through comprehensive psychiatric evaluations, personalized treatment plans, and holistic care, I aim to help individuals overcome challenges such as anxiety, depression, ADHD, PTSD, and addiction.
