More Information

At Mindful Health Solutions, our dedicated and skilled psychiatrists work tirelessly to ensure that each patient who walks through the doors of our San Francisco (Union Square) mental health clinic is treated with respect and compassion. We understand how difficult it can be to navigate the struggles of everyday life when you are suffering from a mental illness or clinical depression, and our goal is to help you mitigate those difficulties so you can live your best life. We help patients with both antidepressant and medication needs as well as offer the most advanced treatments available. We treat a variety of mental health conditions, including ADHD, OCD, and anxiety. Each of our mental health clinics and end-to-end care has been designed around a comfortable, thoughtful patient experience where we listen to you. Our San Francisco (Union Square) psychiatrists and other members of your care team will consult with you and provide you with an individualized plan, often including medication assessment and management service. And if you’re unable to come into our San Francisco (Union Square) office, we offer telepsychiatry, allowing you to get care from wherever you are. Plus, we accept all major insurances.

The primary forms of treatments we offer, especially for treatment resistant depression, are Transcranial Magnetic Stimulation (TMS therapy) and esketamine nasal spray, both alternatives to antidepressants alone, covered by most insurance plans, and proven to show great results. We also offer testing and ADHD treatment plans with psychiatrists experienced in diagnosing ADHD and helping patients find relief. Your comprehensive care team may also include one of our PMHNPs or one of our psychotherapists.
