Dr. Tanika Gayle
Clinical Psychologist
PSY23903
The core of my work is to help people operate from the best in themselves as an individual and in relationship with others. My work helps individuals develop a state of balance by increasing one true, solid sense of self and the ability to take care of self while working through difficulties that life throws at you. Key tools in accomplishing this are by helping individuals self confront and self validate and stay true to ones' integrity. I work with individuals dealing with everyday life stressors, individuals discovering their sense of identity, and various discomforts such as depression, anxiety, relationship issues, and family issues. I have a special interest in treating individuals, families, couples, and intimacy issues which includes sex therapy. In addition to providing therapy, being the owner/clinical director of Collaborative Psychology Group, I currently am the program manager and primary supervisor for Family Support Services at the Inland Empire Ronald McDonald House. It is a practicum training site for marriage and family therapist, social work and psychology doctorate students. In addition I also have a practicum training program at Collaborative Psychology Group for Loma Linda University master and doctoral students.

Elizabeth Dupray
Marriage and Family Therapist
LMFT102612
I am a licensed Marriage and Family therapist who began my educational journey later in life. My life's experiences led me to seek a career more meaningful in helping others. Prior to my education in counseling I worked for many years in the grocery business as a retail clerk, getting to know all the customers who came through my lane. I believe that job was a great training ground for my current career as everyone from all walks of life goes to the grocery store. My keen observation of each person and family dynamics was educational in itself. My years of internship and counseling have been meaningful when clients have made progress and I get to be a part of their journey. The populations I have the most experience in are clients struggling with anxiety, depression, domestic violence, strained marriages, and relationships. I have helped women stuck in the cycle of abuse and codependency and understanding the pain from my own life's experiences. I have worked with families and individuals struggling with family members addicted to different substances.

Hello/Saludos! I welcome you to the start of your therapy journey and your desire to learn about yourself, grow, and heal.

I work with adults of all ages and college students. I have a diverse clinical background ranging from working in non-profits, community mental health, LGBT centers, and universities. My areas of specialization are in LGB and Transgender affirmative psychotherapy, Latina/x mental health, relationship challenges, depression, domestic/interpersonal violence, substance use, and cultural identity challenges.

I work from an integrative, multiculturally centered, and tailored approach to meet your specific needs. I will support you from a compassionate, non-judgmental, and caring stance.

You will notice improvements in your self-esteem and relationships. I look forward to working with you and supporting you in thriving and feeling better. I love being a therapist and witnessing the transformation that can happen in therapy. I want you to live your best life as they say.
