What kind of treatments do you specialize in?

Dr. Sherwood specializes in a family systems approach to treatment, in which she helps her clients examine and resolve their challenges in the context of family units, where issues often begin. For many of her clients, these challenges have negatively impacted their self-esteem and hindered their ability to cope in relationships, in school, at work, and elsewhere. Families in conflict, as well as couples and individuals with struggles and concerns related to their family of origin, including mood disorders, anxiety, trauma, personality disorders, and addiction, benefit from family systems therapy. In addition, Dr. Sherwood prefers a multidisciplinary approach in her work, and, as such, she regularly consults with primary care physicians, pediatricians, psychiatrists, school personnel, nutritionists, attorneys’ and other professionals on her clients’ behalf.

In her clinical work with children, adolescents, and adults, Ms. Ayers works from psychodynamic, person-in-environment, and humanistic approaches, while implementing techniques and interventions from Cognitive Behavioral and Dialectical Behavior Therapy as well as expressive therapies. Ms. Ayers is a strong proponent of involving loved ones in her clients’ care and she has experience leading caregiver support groups as well as family and couples therapy.

How will your treatments apply to my specific needs?

Your first several sessions will involve a comprehensive evaluation of your needs and goals. By the end of the evaluation, your provider will offer you her initial impressions of what your work together might encompass. During this time, you are also asked to assess if you are comfortable working with your provider. You are encouraged to ask questions at any time. If at any time you would like to seek a second opinion or pursue treatment elsewhere, we are happy to refer you to another mental health provider.

Are there any services that OHPS doesn’t offer?

It’s important to note that OHPS is NOT an emergency clinic. If you are experiencing a life-threatening emergency, please call 911 or go to the nearest emergency room immediately.

OHPS does not offer:

  • Emergency or walk-in appointments.
  • Child custody evaluations or psychological evaluations in cases involving litigation.
  • Services for chronic substance abuse and dependence.
  • Services for medically-involved eating disorders without consent of your physician.
  • Court-ordered treatments, including therapy or evaluations for individuals currently on probation or parole.
  • Treatment for individuals with serious mental illnesses who are non-compliant with medication.

Also, OHPS is not a crisis center and, therefore, is not equipped to meet the needs of individuals who require 24-hour support. If we are not able to provide the level of care that you require, you will be referred to a treatment center that is better able to assist you.
