Cate believes we are each unique in our experiences and our expression of those experiences.

Cate believes medication can be a solid foundation or a transitional step toward improved mental health. She also believes in 'less is more' when it comes to medications.

During each 30-minute session, Cate will employ supportive, motivational and reframing among other therapeutic techniques to foster confidence, insight and healing as you navigate your mental health journey. She believes the mind, body and spirit are an integrated whole and therefore encourages holistic self-care such as healthy eating, good sleep hygiene, regular exercise and mindfulness practices as part of your treatment. If more intensive therapy is needed, Cate will work with your therapist or make appropriate referrals as needed.
