We Are the Industry Experts

Expert Personnel

At AAC, we employ industry experts to lead the development of innovative practices and research to create the best possible environment of care for each of our patients. Our qualified medical experts are deeply passionate about addiction treatment and recovery, and are committed to ensuring that each patient is treated as an individual.

Dual Diagnosis

Dual diagnosis treatment is the simultaneous treatment of substance use disorder and co-occurring mental health issues. The co-occurring disorder approach helps to combat an endless cycle of unhealthy living caused by addiction and a mental health issue (e.g. anxiety, depression, PTSD, etc.), and it is built into the very core of AAC’s treatment programs.

Personalized Treatment

As a patient at AAC, we see you as more than your addiction. You have unique strengths, potential, and challenges, and we believe that your addiction treatment should be personalized. Our goal and focus is to treat the whole person, which means addressing co-occurring mental illness, physical wellness, social issues, and more during your treatment.

Clinical Expertise

We use research-based treatments to help those with drug addiction, alcohol addiction, and co-occurring mental and behavioral health issues. Under the guidance of our chief medical officer, AAC’s programs are made up of medical professionals that specialize in addiction treatment, which includes physicians, registered nurses, licensed marriage and family therapists, social workers, psychologists, and psychiatrists. We have a high staff-to-patient ratio to ensure all of our patients receive the highest quality care an attention; and many of our staff are in recovery themselves—so they understand what you are going through.

Our success rate is more double the national average, and we have been featured in Forbes, Fortune, Fox News, Daily Mail, Bustle, and USA Today.

Dr. Mark Calarco

National Medical Director for Clinical Diagnostics

Dr. Mark Calarco has served as the national medical director for American Addiction Centers from 2013 – 2018. With the addition of Dr. Lawrence Weinstein, who assumed that position in August 2018, he has been appointed national medical director for clinical diagnostics. In this position, he works closely with Addiction Labs to conduct medical and laboratory research as well as develop innovative products and services that will improve patient outcomes. Calarco brings more than 25 years of experience to the role, including a background in family and emergency medicine.

Calarco is also a thought leader in the addiction industry and an established researcher. In 2017, he led two original studies at AAC with the findings presented to the American Academy of Addiction Psychology. His talents also include speaking five languages – Spanish, French, German, Japanese and Italian.

Patient Safety

COVID-19 Protocol

AAC is leading the way in the addiction treatment industry by now testing each patient admitted to any one of its treatment centers for COVID-19. The new safety protocol is significant news for patients seeking addiction treatment in the midst of the COVID-19 pandemic.

Tests will also be available to current patients and staff exhibiting symptoms, in accordance with guidelines from the Centers of Disease Control and Prevention. AAC’s lab, Addiction Labs, worked tirelessly to piece together all the necessary elements to conduct the testing with fast turnarounds of 48 hours or less.

“The safety of our patients and staff is paramount and we were not going to take ‘no’ for an answer,” said Shannon Myers, Addiction Labs supervisor. “And with that came hundreds, if not thousands, of phone calls with vendors.”

AAC is one of a few treatment providers to have an in-house lab and the capability to offer COVID-19 testing for its patients. Addiction Labs has the capacity to run 2,400 tests a day. The lab also went beyond standard testing protocols to ensure an accuracy rate of 95% or higher.

Addiction Labs

AAC’s utilization of an addiction-focused laboratory sets us apart from most addiction treatment centers. Addiction Labs of America is a high-tech laboratory that caters to the unique testing and monitoring challenges of addiction treatment.

Through our diagnostic testing, we are able to pinpoint specific genetic indicators to guide the best treatment and medication regimen for each individual patient. Having laboratory services as part of our family of treatment and recovery portfolio ensure seamless, timely, secure, and accurate testing.

Many individuals struggling with the disease of addiction avoid going to a healthcare provider for years at a time, or only go to try to obtain their drug of choice and do not get a full exam. Many of our patients didn’t want to see a healthcare provider because they didn’t want to be confronted about their addiction. Through Addiction Labs of America, healthcare providers at AAC facilities are able to evaluate for various health concerns that may have persisted undetected or unidentified. Routine labs, such as checking a patient’s blood sugar and cholesterol, can identify common health conditions that need treatment, or may even allow practitioners to create a plan to prevent issues from arising.
