Heather Allen


7 years in recovery
Every employee at The Hills is a success story, and Heather Allen is no exception. After spending almost a decade and a half ensconced in her addiction, Heather was arrested in 2004 for possession and found herself incarcerated for 4 months.  Rather than let this event define her, Heather used it to galvanize her commitment to change.  Upon her release, she spent 6 months in a residential treatment program where she wrestled the urge to quit and self destruct before moving on to yet another 6 months in an outpatient program.  Impoverished but persevering, Heather gave birth to her first child within the first 18 months of her sobriety and quit her job as a waitress to pursue a career in recovery by taking a job at the self same treatment center that had saved her life.

It was then that she enrolled at a community college in a chemical dependency program and dedicated herself to becoming a credentialed treatment worker.  Heather completed the program and made the Dean’s List while working full time and schooling part time and grew pregnant with her second child.  Her work at the treatment facility led to her wearing many caps, starting as a graveyard facility monitor and working her way up to counselor where she oversaw a caseload of 7 women, facilitated groups, and managed both the QA and EHR for the facility.

Seeing an opportunity to put her newfound skill set to the test, Heather left that job after 5 years and joined us here at The Hills where she eventually put on the hat she currently wears proudly as Residential Supervisor.  Literally everything she does is born of the love she has for her two children and her commitment to remain clean and sober one day at a time.  Her plan is to continue her education at Antioch University.

Tracy Monteverde, LVN


18 years in recovery

Tracey Monteverde’s worked in treatment since 1999 with a special interest in detoxing patients. Her formidable intellect and warm-but-no-nonsense bedside manner makes her uniquely qualified to walk clients at The Hills through the process of getting clean and sober.  Her dedication to our clients’ well-being is without equal, and she will often times continue to work with the clients long after treatment in order to help them coordinate their health and medications.  Her extensive background in Private Detox, Non-Profit Drug and Alcohol Treatment, Psychiatric Hospitals and High-End Substance Abuse Facilities affords her an empathy that enables her to not only connect with our clients, but genuinely care for them as they embark upon the road to recovery.

Alana Tsipris, LVN


The war on addiction is not one without casualties.  As friends began to suffer and die from heroin overdoses, Alana Tsipris surveyed the wreckage of her life and realized that she was standing at a ground zero of her own holocaust, and that it was time for her to take action.  Having become a Licensed Vocational Nurse in 2010, Alana left a nursing position at American United Health Care and went to work at Malibu Horizon rehab in Malibu where she quickly began to make a difference.

Clients responded to her warm, and affable nature and it wasn’t long before she found herself in a leadership position at yet another prestigious Malibu facility, Pacific Coast Detox.  As her reputation as an LVN in the treatment community garnered more and more positive attention, Alana struggled to keep her eye on the prize.  “I knew that I was helping people”, she explains, “but my friends were still overdosing and I needed to feel as though I were really making a difference.  And, I couldn’t do that way out in Malibu.  I needed to be on the frontlines.”  She found those frontlines here at The Hills in the summer of 2014, bringing a fresh perspective on client care with her.  And it is a perspective that not only augments The Hills’ already-high standards, but also guarantees that you and your loved ones get what you need to win your own battles against the disease of addiction.  “This is just my way of making sure that no one has to go through the pain and loss that I’ve gone through”, Alana adds.  “It’s my small way of making a difference”.

Business & Administration

Doree E. Cambas


11 years in recovery

Doree Cambas began her career in treatment 12 years ago as an administrative assistant at a high-end treatment facility, but soon branched out and quickly assumed other roles and duties. Fueled only by a voracious appetite for challenge and the need to contribute more, Doree found herself rocketing through titles as she went from Technician to Office Manager to Quality Assurance Coordinator to Executive Assistant and Operations Manager. Eventually, she found herself here at The Hills, serving as the company’s Director of Operations, where she managed the full range of administrative, logistical and operational duties in a wide variety of program areas including human resources, financial, budgeting, information technology, property management and procurement.

Today, acting as Executive Vice President for The Hills, Doree oversees the day-to-day operations of the company, manages a multitude of budgets and works hand-in-hand with both the company’s Owner as well as the Program Director to develop and direct programs designed to meet the needs of our clientele, vendors, constituents, staff, and District and Federal Agencies. Her devotion to her husband and child and her affable spirit are paramount only to her need to serve our clients as they make ready to transform their lives and do what she, herself, has already done: Achieve the Impossible.

Oren Pius


13 years in recovery

When he was Director of Admissions, Oren Pius was grateful to have the opportunity to help addicts and alcoholics find the right rehab. Serving as The Hills’ first point of contact for many families, Oren worked around the clock to reach out to callers and literally help them get help for themselves or their loved ones.  A recovering addict himself, he spent ten years of his life as a slave to his addiction to Heroin, Cocaine and Methadone before ultimately getting clean and sober himself.  In 2003, Pius began working in treatment, first as a clinical assistant, and then as director of operations, call center manager, and residential supervisor before finding his niche with insurance billing and marketing, where he acted as a vital liaison between insurance companies and our clients, making him an essential part of every addict and alcoholic’s recovery process.  As Executive Vice President of The Hills, Oren continues his tireless tradition of counseling families and paving the way for treatment for addicts and alcoholics who, like himself, were lost and in desperate need of a way out of the nightmare of addiction.  Championing the cause of anyone who wants to turn their lives around, Oren remains steadfast in his conviction that, no matter who they are, and no matter how many times they’ve tried and failed, every addict deserves a shot at redemption.

Shawn Monterroso


“Each of us must work for their own improvement, while at the same time share a general responsibility for all humanity.”   -Marie Curie

Growing up, Shawn Monterroso’s mother always reiterated that, “We are all God’s Children”, which instilled within her a deep appreciation and respect for the concept of, “People helping people”. Her career began in consumer sales and services where she developed the skill set of uniting management with their staff and employees to the benefit of the corporation, thus building strong teams for success.  This penchant for investigating and resolving conflict led to Shawn’s career as a Human Resources Manager.  “My favorite part of working at The Hills is connecting with the people”, she says.  “I take great pleasure providing a shoulder to lean on or even financial guidance as our employees wind their ways through the daunting tasks set before them”.  Whether it be simple things like negotiating health benefits through our insurance carriers, resolving problems with management, or the complicated process of walking new hires through enrollment in our 401K plan, Shawn Monterroso does it all with a welcoming smile and an understanding ear.

A healthy working environment, she believes, is the first step toward enabling the staff at The Hills to better serve the clients themselves.  A force to be reckoned with, Monterroso’s areas of responsibility include recruitment and staffing, benefits, classification and compensation, learning and development, employee relations and career services, payroll, information management, and leadership development, as well as non-academic aspects of the faculty personnel system.  This, of course, makes her both the team’s Disciplinarian and “Den Mother”, and we are honored to have her with us.

Insurance Department

Toni Kells, M.A. CATCIV


17 years in recovery

With over a decade and a half of recovery under her belt, Toni Kells is practically a force of nature. Looking at her credentials, one would honestly think that there is nothing she cannot do, which is why The Hills is so proud to have her on our team. Toni began working in treatment in 2003 and began carving a path of accomplishments almost immediately thereafter. She has been a certified Drug and Alcohol Counselor for 10 years with special certifications in Anger Management and Domestic Counseling.

In 2012, she earned her Master’s Degree in Psychology with an emphasis in Marriage and Family Therapy. With these credentials in hand, Kells went on to work in high-end private treatment, non-profit treatment specializing in co-occurring disorders, evidence based treatment and best practices. She cut her teeth with a stint working with the criminal justice population and acquired an edge that addicts not only relate but truly respond to. Her experience working with Insurance Utilization Review in 2007 with the world renowned rehab Cri-Help, however, made her the perfect candidate to head our own Insurance Review Departments. Having worked closely with commercial insurance agencies such as Kaiser, United Health Care, Pacific Care, Blue Shield, and Magellan, Toni developed relationships and a street-smart savvy that makes treatment for almost everyone possible while assuring that we remain in compliance with CARF, JCAHO and State Standards, as well as DMH documentation.
