Dr. Jonathan Ni is a board certified psychiatrist serving adults of all ages across California. He was born and raised in California, received his medical degree from Boston University School of Medicine, and completed his psychiatry training at the University of Illinois in Chicago, where he gained valuable clinical experience treating a wide range of psychiatric disorders within a diverse population. Dr. Ni believes that effective mental health care begins with developing a clear understanding of each individual’s unique background and experiences. He is interested in helping patients achieve their goals not only with regards to alleviating and addressing their symptoms, but also in the broader context of their lives in general. He works closely with his patients to identify thinking patterns, behaviors, and other factors that may be contributing to their symptoms. In collaboration with the patient, he develops a comprehensive treatment plan that may include medication management, psychotherapy, and/or lifestyle adjustments, ensuring that each patient receives personalized care aimed at promoting meaningful change.

I can’t say enough positive things about LifeStance. The Patient Portal is incredibly convenient and lets me get in touch with my doctor if I have timely updates for them. Dr. Ni has been so incredibly supportive and patient as we worked through the pros and cons of all the medical treatments I could possibly undertake. He has given clear guidance on why we should try something new and always listens when I make suggestions or tell him something isn’t working out for me. I couldn’t recommend LifeStance enough and more specifically Dr. Jonathan Ni.

I’m relatively new to LifeStance and working with Dr. Ni but I couldn’t be happier. Dr. No is great and a good listener and I’ve already learned a lot - even just today. I look forward to growing and evolving with him. Highly recommend him and LifeStance.
