Mary Costello Stevens

Mary Costello Stevens I am a therapist who loves helping people who are dealing with difficult times. I provide a safe and confidential place where my clients can share their thoughts and feelings, find support, look at what’s working and what’s not, and learn new strategies to deal with negative emotions and situations.


My desire is to promote self-exploration and empowerment so my clients can let go of negative beliefs, foster deeper relationships, and achieve increased self-esteem and happiness. I consider the self holistically and provide support that’s focused on individual needs as well as improving experiences with family, peers, work or school, and society as a whole. I partner with my clients, utilizing a variety of counseling approaches to help them heal and become more hopeful and resilient.


I started my private practice in 2012 in the Denver Tech Center. I feel honored to support individuals, couples, families, and teens as they cope with difficulties, expand life’s possibilities, and thrive.
