My Approach to Helping

Are you exhausted of running from problems or confronted with current challenges? Are past problemschallenges preventing you from reaching your goals in your close relationships, family, work or school? Most clients sense there is an obstacle especially when the problems begin to negatively impact these areas or find it difficult to carry out tasks at school or work. If this sounds like you, it is important to overcome these struggles with meaningful support.
I love being a Licensed Marriage & Family Therapist. I practice person-centered therapy, provide a supportive environment within a non-judgmental climate. This holds as an anchor for my clients as they collaborate, discover answers, build on their strengths, develop an understanding, recognize difficult emotions, and integrate all facets of themself in order to construct a sense of wholeness. With a background as an EMDR trained therapist, I have discovered this intervention to be most helpful addressing past traumas. I have the experience to help you achieve your goals, surpass these past struggles, and live a more meaningful life. Currently, I have nine years of experience providing therapy to individuals, couples, groups, and families. I offer a Christian perspective to help clients become healthy spiritually. I have also taught group courses for Anger Management and Nurturing Parenting.
Foremost, it is a privilege to see a client’s new energy, shifts in perspective with more clarity, acceptance of their truths and spark of healing for the first time.

“It is an absolute human certainty that no one can know his own beauty or perceive a sense of his own worth until it has been reflected back to him in the mirror of another loving, caring human being.” -John Joseph Powell
