Message to clients

You may be feeling lonely, stuck, anxious, sad or struggling in your relationships. You've tried to manage on your own but now realize that a professional may be needed to help you move past this challenging time in your life. You are not alone; many people seek therapy for just these reasons and psychotherapy is an effective treatment. I use warmth, humor, mindfulness and research-backed methods to help you overcome your anxieties, sadness, roadblocks and struggles.

I specialize in relationships, whether that is with your partner, family, grieving a relationship loss, or as a single person dating. The techniques I use have been shown to help people move through painful times to find more satisfaction, ease and joy.


Anxiety - Coping with excessive worry, nervousness, or stress; intense discomfort in social settings (social anxiety); sudden and intense feelings of panic (panic disorder)

Depression - Providing support and promoting healing of hopelessness, low motivation and energy, sadness, irritability, sleep disturbance, and loss of interest and pleasure in life

Family therapy - Promoting communication and supporting family members to address challenges and reduce conflict and distress

Couples therapy - Addressing relationship challenges and life transitions; strengthening communication and feelings of security, desire, connection, and love

Relationship issues - Understanding one’s wants and needs in relationships; exploring patterns of interaction, addressing concerns, and strengthening satisfaction in relationships and dating

Dating coaching - Helping clients achieve more joy, connection and flow in their single lives and through the dating process by applying cognitive behavioral and mindfulness approaches to traditional coaching
