Why Darren Lockie Built a Smaller Rehab on Purpose

Jintara is a small private residential rehab in Chiang Mai, founded in January 2022 by Darren Lockie after seventeen years operating licensed addiction treatment facilities in Thailand.

If you are reading a founder story, you are usually trying to work out one thing: whether the person running this place knows what they are doing, or whether it is a business that found a profitable category. Jintara takes a maximum of ten adults at any one time and operates under licence number SFD 50:13-106 issued by Thailand's Ministry of Public Health. The facility is owned and operated by Lanna Health Care Company Limited.

Darren moved into addiction treatment around 2008. That route is set out in more depth in his notes on choosing a rehab abroad, and it is the reason this place looks the way it does. His first significant operational role was leading DARA Rehab on Koh Chang island, where he oversaw the program, staffing, admissions and clinical standards, and where he watched a facility grow to a scale he later decided not to repeat.

Running a high-census residential facility taught Darren one consistent lesson: the things that matter most in addiction treatment are the first things to slip as numbers climb.

Consistent staff relationships. Unhurried individual sessions. The ability to notice a change in someone's mood before it becomes a crisis. A facility at forty or fifty clients becomes operationally efficient, and it stops being clinically intimate. Nobody decides that. It is arithmetic.

He wanted a place where a 3.2 to 1 staff-to-client ratio was a daily operational reality rather than a marketing line. That means around thirty-two staff for a maximum of ten clients. It means the cook knows your dietary needs, the support workers know your sleep patterns, and the therapists are not carrying caseloads of twenty.

The referral model taught him the second lesson. Jintara runs on direct self-referral and owner-led admissions, with no commission-based referrers and no financial incentive to admit someone who is not a clinical fit. Facilities that depend on referring agencies carry a structural pressure instead, because beds need to stay full to cover costs, and that pressure can shape who gets admitted and for how long.

When Thailand closed its borders in 2020, residential treatment for international clients stopped, and the interruption ran through most of 2021.

For most operators that was simply damage. For Darren it was also the first pause in more than a decade of running large facilities, and it forced a question he had never had room to ask: if you started again, knowing everything you now know, what would you actually build.

Jintara opened in January 2022 as Thailand reopened. The property was found in Chiang Mai, the city where he had lived for years. The client ceiling was set at ten. The staff ratio was set higher than any other residential facility in Thailand by his own description. Admissions were kept owner-led from the first day, so that fit, safety and expectations could be assessed before anyone committed to anything.

The ten-client ceiling is a clinical decision, not a function of how many beds fit in the property.

With ten clients and three therapists, each person gets considerably more individual and group therapy time than most residential programs deliver. That ratio shapes every part of the treatment program, and it is why small caseloads matter so much. A therapist has time to think about someone between sessions, to coordinate with the nursing team on medication and mood, and to catch the things that get missed when one clinician is responsible for fifteen or twenty people at once.

The small group changes the social environment too, and that matters clinically. People in early recovery are acutely tuned to whether they are being seen as an individual or processed as a case. In a group of ten adults there is nowhere to hide behind the dynamics of a large cohort, so the work tends to get done more directly. That intensity does not suit everyone, and it is also where the benefit comes from.

The most consequential decision Darren made when building Jintara was hiring Denise O'Leary as Clinical Director.

Denise holds a Master of Arts in Counselling Psychology, completed Beck Institute training in cognitive behavioural therapy for addiction, and is certified by EMDRIA as an EMDR therapist. Based on available verification, she is the only EMDRIA-certified EMDR therapist practising in Thailand.

Trauma sits underneath a large share of the substance use that arrives here. That is why EMDR therapy matters, because trauma-focused therapy is a core component of trauma-informed care in behavioural health settings, and processing typically begins after medical stabilisation and produces the best results for clients staying sixty days or longer. For thirty-day clients the preparation begins during the stay and continues with a referred therapist at home, supported by a written handover report.

Lertkhwan Sukpia, known as Khun Khwan, leads the nursing team as Head Nurse and Operations Manager. She is the named responsible practitioner on Jintara's Ministry of Public Health facility licence and oversees clinical compliance across every medical and operational procedure. Between Denise's clinical leadership and Khun Khwan's nursing management, the structure here is clinical from the top rather than operationally driven.

Every enquiry goes through Darren personally, and a meaningful number of them end with him recommending somewhere else.

There is no call centre, no admissions coordinator working from a script, and no pressure to hit a bed count by month end. The medical detox here is clinical and well staffed, and it still operates within the parameters of a licensed residential facility rather than a hospital ward. If someone is not a clinical fit for what this facility can safely provide, he says so and points them toward a place that is.

This comes directly from his view of what trust costs in this industry. He has said publicly that someone may well take his advice on how to choose a rehab and then choose a different one, and that this is an acceptable outcome. The aim is that people find the right help.
