JULY openings! I believe good mental health is the key to happiness and balance in life. Seeking help can be one of the hardest parts, and finding a “good fit” can be even more challenging! I’ve been practicing for 15 years, but in the last decade, have shifted my main focus to adults and couples that are working to improve their mental health and communication.
