You can recover and thrive

SunCloud Health is recognized locally and nationally for treating you, the whole person, in a community where you’ll feel empowered, supported, and connected; that’s what we do best.

Unlike many providers that say they can treat co-occurring disorders, substance use, eating disorders, mood disorders, and related traumas, at SunCloud Health, we actually do.

We don’t toss around buzzwords. Instead, our staff is cross-trained in treating a wide range of conditions in a center that addresses the impact of traumatic life experiences on all of them. We know that your struggles are not only in your mind – your physical health, your relationships, and your life experiences play a part, too. Healing begins with a program that works with your body, mind, and spirit. We are with you every step of the way as you move toward a life of wellness.

Lasting Change That Begins with Effective Behavioral Health Care

SunCloud Health is a private outpatient and residential treatment provider with five locations in Northbrook, Naperville, Matteson, and Chicago (Lincoln Park), IL. Guided by Kim Dennis, MD, our team provides highly individualized and effective care for adults and adolescents struggling with one or more of these life issues. We bring special expertise to the challenge of helping those with a dual diagnosis and complex co-occurring disorders.

Adolescent Treatment Programs
“At SunCloud Health, we understand that ‘co-occurring disorder’ means multiple primary illnesses at the same time in any one person.

A person with multiple primary illnesses deserves to have each of them fully addressed using a coherent treatment model, and ideally one that constantly has an eye on the role of unresolved trauma in perpetuating addiction, eating disorders, and mood disorders. This is the work we do at SunCloud Health. While it would be much easier to focus on one ‘primary’ illness, the single-disease focus approach has not worked well for our patient population. We are here to serve individuals with complex co-occurring disorders. And we do so in a way that sets them up to achieve sustainable recovery and fuller living experience.

-Kim Dennis, MD, CEDS

What Makes SunCloud Health Unique

At SunCloud Health, advanced science comes together with caring, individual attention. One of the greatest gifts we offer patients is the opportunity to be treated as complex human beings and not simply as a “primary diagnosis.”

You are an individual, not a diagnosis, and so understanding your life story is the crucial first step in choosing the therapeutic approaches that will create real progress for you.

Every patient we see has a unique biology, unique genes, and a unique set of co-occurring disorders, even when behavioral symptoms might look alike. Our patients don’t fit neatly into one diagnostic box, and our treatment approach does not in any way represent a “one size fits all” model.

Thus, we don’t “track” people by flawed DMS-ology broad categories of disease. Rather, we take behavioral and neurobiological phenotype into account, we take dimensions that transcend diagnostic categories into account, we take underlying neurobiology into account, we take biodiversity into account, and we take nuance into account. Ours is individualized, sophisticated, nuanced care. It is advanced and interested care for co-occurring disorders and trauma.

This model has been utilized and refined by our Chief Medical Officer and CEO, Dr. Kim Dennis, M.D., for nearly 20 years. While not for everyone, for our patients, it’s the only way. Approaching their care in this way enables us to address all of them in a unified treatment setting, as complex human beings and at the same time. You can live free of the vicious cycle of your disease. SunCloud Health is here to help you return to yourself with targeted treatment that sees you as a whole person.

A Personal Message from Dr. Kim

The SC team comprises of a multidisciplinary team of health care providers who help you develop an individualized treatment plan to reach your goals. Our team consists of psychiatrists, registered dieticians, registered nurses, psychologists, therapists and counselors whose specialties include addiction, eating disorders, mood disorders and trauma recovery.

The community at SunCloud includes you, fellow patients seeking greater health themselves and the SC staff. At SCH we focus both on the primary behavioral symptoms interfering with your life, as well as the underlying biological, psychological, social and spiritual factors, including adverse childhood experiences, that interfere with your ability to live a meaningful, joyful and free life.

We use evidence-based treatment modalities to execute our mission to provide integrated care to persons with complex, co-occurring conditions who have not been adequately helped by treatment models that focus on one “primary” condition.

We use a sophisticated treatment approach addressing multiple co-occurring disorders at the same time, under one roof in an integrated fashion.”

Your voice. Your choice. Our team.

At SunCloud Health, we believe treatment begins with dignity and respect.

Your voice is valued – we start by listening. Every patient has a say in their goals and the approaches that feel right for them, whether that’s shaping a nutrition plan, preference of treatment modalities, making informed decisions about medications, or defining what values are most important in their life.

Your choice guides your treatment. We know that care is most effective when patients autonomy in their care, and are not coerced into conforming to a one-size-fits-all model. Having options creates space for personal responsibility, agency, and sustainable recovery.

Our team fights alongside you every step of the way with compassion and care. With a team of highly trained psychiatrists dedicated to each of our sites, teams of experienced multidisciplinary clinicians, and a trauma-informed, holistic framework, we deliver evidence-based care that affirms identity and culture, includes family, and treats the whole person. Our commitment to clinical excellence is matched only by our compassion and respect for those we serve.

Together, we create an individualized treatment plans that truly fits your needs and your preferences, including food and body preferences for patients with eating disorders. Our clinicians are distinguished by their responsiveness to each person’s story, strengths, and needs—so healing can take root in a way that lasts.
