Expertise and Approach

Circadian's Mission 

Welcome to Circadian Mental Health Services.  We specialize in helping people find their rhythm.  Your circadian rhythm is your 24-hour internal clock that regulates your levels of sleepiness and alertness.  It works best when you have regular patterns both with sleep and with other activities throughout the day.  If it is disrupted by life events or stressors, you can feel out of sort and it can be harder to be present and function in life.  Those of us at Circadian MHS strive to help you find your natural rhythm so that you can enjoy life to the fullest and be as present as possible.

Circadian Mental Health Services offers clients the tools to gain balance and a functional rhythm so that they can live healthy and productive lives.  Therapists use an eclectic therapeutic approach that draws from such theories as Family Systems, Cognitive-Behavioral, Psychodynamic, and Solution-Focused.  Approaches are tailored to the client as no one person has the same rhythm as another.  

Change can often be scary and people tend to revert back to old patterns of behavior because it is what's familiar.  It takes courage to be willing to step outside of your comfort zone and break these patterns and find a new rhythm.  Circadian Mental Health Services hopes to help you on your journey to giving yourself a new and much deserved experience.

Dr. Kristina Miholich, Psy.D., Owner

Kristina Miholich is a licensed clinical psychologist (PSY25801) and Reiki Master.  She earned her Doctorate of Psychology from Alliant International University in 2011 and has been working in private practice since 2016. Dr. Miholich began her Reiki training in 2020 and completed her Reiki Master training in 2022. 

Dr. Miholich works with each of her clients individually to identify their specific concerns and needs. She practices from the framework of somatic psychology, which means that she believes that there is a strong connection between our mind, spirit, and body. She believes that without healing our body, or nervous system, with the help of therapy and energy healing we cannot heal our minds and emotions. Therefore, her treatment integrates the use of thoughts and emotions as well as the information garnered from the body in order to heal oneself. Dr. Miholich sees every individual as having the capacity to heal themselves and she as the therapist serves as a guide in that process. Dr. Miholich often describes herself as specializing in assisting individuals in reprogramming their body and mind so that they are no longer plagued by negativity and can instead step into living life from a joyful place.

Individual Therapy

This type of therapy is a collaborative process between the therapist and the client with the aim of making shifts or changes so that quality of life is improved.  Sessions are typically 45 minutes.  Individual therapy is useful for many different issues including symptom management, relationship difficulties, work/school problems, life transitions, stress management, and personal growth.  

Couples Therapy

This type of therapy is a collaborative process between the therapist and the couple.  Sessions are typically 45-55 minutes.  The goals are to shift or change dysfunctional patterns of engagement between the couple so as to manage problems more effectively, prevent small problems from turning into large problems, and to reconnect emotionally with your partner.  Couples counseling can improve a person's physical as well as mental health, in addition to improving the relationship.  

Family Therapy

This type of therapy is a collaborative process between the therapist and the family.  Sessions are typically 45-55 minutes.  The goal is for everyone in the family to make shifts versus just one person making the change so that it is more long-lasting.  If only one person makes change and then he/she return to the same environment, then he/she is likely to fall back into old patterns of engaging with others and the change will not last.  However, if the family as a whole makes shifts, then the change is likely to be more sustaining.  This approach is particularly encouraged with children and adolescents and also for families struggling with a loved one with mental illness.
