About Theressa

Harvest House is born out of a deep desire to develop and grow healthy, meaningful, attached relationships with God, self, and one another.   The principle of relationship is the fundamental organizing structure of our universe, our world, and ourselves.  This principle guides our work as clinicians, colleagues, and friends.  This work is hard work; however, it is necessary work.   


Marriage and Family Therapists are unique in the mental health field because of our systemic orientation.  Our education and extensive training in the dynamics of relationships set us apart from other clinical practitioners.


While relationships are complicated, we do our best and are often quite successful. However, there are other times that we have done all that we know to do, and we are still stuck.  While struggling is an essential part of personal and relationship growth, it does not make sense to continue to fight when there is help available.   


One of the most beneficial aspects of therapy is the objectivity and relationship expertise of a Marriage and Family Therapist.  Therapy allows growing in self-awareness, boundary development, healthy communication skills, and insight for change.  Therapy can be a hard thing to initiate, but the benefits can be life-altering.  The AAMFT shares the following… 


“Studies also show that clients are highly satisfied with the services of Marriage and Family Therapists. Clients report marked improvement in work productivity, co-worker relationships, family relationships, partner relationships, emotional health, overall health, social life, and community involvement. 


In a recent study, consumers reported that marriage and family therapists are the mental health professionals they would most likely recommend to friends. Over 98 percent of clients of marriage and family therapists report therapy services as good or excellent.”


Give us a call. We provide a warm, safe, and confidential place to work out issues.  You may not know “how this therapy thing works,” but we do.  Call us. Ask us. We are here to help.
