About Us

Our goal at Sunflower Psychiatry is to help our clients achieve a balanced lifestyle.  We develop a three-pronged approach to patient care by incorporating nutritional, chemical and therapeutic aspects catered towards each client’s needs.

There is often more to Psychiatry than what is contained in the mind. We know that throwing pills at patients is not the best way to treat everyone. Our approach offers alternative interventions-with a focus on diet and nutrition- in addition to traditional medication management. 

We treat a variety of mental health issues, ranging from insomnia, ADHD, Depression, PTSD, generalized anxiety, panic disorder, social anxiety, to eco-anxiety and OCD. We can also help taper down medications in those who seek to reduce or stop their previous treatment. With the patient, we develop a plan to make goals attainable so progress is maintainable.  

If you are interested in working with medical professionals who are non-judgmental, perceptive, and willing to work with you, Sunflower Psychiatry would love to help you make your world brighter.
