Obsessive-compulsive disorder therapists & psychiatrists in Upland, CA

I am a seasoned behavioral health and forensic psychology leader with over 20 years of experience in county, correctional, and community settings. I hold a Ph.D. in Clinical Psychology, two master’s degrees, and I am a licensed Marriage & Family Therapist as of 2019. My work centers on trauma‐informed care, substance use, sexual abuse victims and offenders, crisis intervention, and forensic experiences.

My goal is to provide high quality client-centered care, utilizing a humanistic approach. I am focused on validating my client's life experiences and providing a safe and non-judgmental space to share. I also believe in holistic point of view and integrative care of body, mind, and spirit.

My clinical experience includes working with children, teens, and adults with many issues including: grief, work-related stress, anxiety, depression, mood disorders, and neurodivergence (ADHD/Autism).

My name is Kianna, and I have a passion for helping individuals who are battling anxiety, stress, overthinking, and people-pleasing. I work with people who are feeling stuck and in need of more support as they create meaningful change in their lives. My goal is to guide you to a deeper understanding of yourself and what makes you feel your best.

Do you feel like something is wrong with you? Do you wish it would all just stop and go away? Is your child acting out and you don't know why or what to do? If you have had any of these thoughts, then you're in the right place! My practice is based around what happened to us, not what is wrong with us. I am here to support & guide you in processing thoughts and feelings, reflect on experiences, learn new coping skills, and figure out next steps. I will listen, teach, brainstorm, guide and help you build tools to meet your goals.

Life has a way of throwing challenges our way that can feel impossible to navigate alone, but you don't have to carry that weight by yourself. With over 30 years of experience as a therapist, I have worked with individuals of all ages—from young children to seniors—helping them find clarity through life’s most difficult transitions. Whether you are dealing with relationship struggles, depression, or the complexities of grief and trauma, my goal is to provide a steady presence that helps you find your way back to yourself. I feel privileged to help my clients achieve their goals and improve their lives by drawing on both my clinical training and the wisdom gained from decades of practice.

I believe that true healing happens when you have a space to speak freely with someone who isn't connected to your daily life or family circle. I bring a blend of professional expertise and extensive life experience to our sessions, which allows me to understand the nuances of the human experience beyond just a clinical lens. Outside of my work in the office, I enjoy staying active in the local community and find that a balanced life helps me show up fully for those I serve. I want my clients to feel safe and empowered during their time with me, knowing they have an experienced advocate committed to their well-being.
