Dr. William Clark serves as Medical Director at Lighthouse Recovery, bringing over a decade of distinguished academic medicine experience to his oversight of psychiatric care within our programs. His journey in psychiatry began with exceptional academic achievement, graduating with honors from the University of Texas at Austin’s prestigious Plan II Liberal Arts Honors Program and earning Phi Beta Kappa recognition before completing his medical degree at UT Health Science Center San Antonio. His excellence continued through residency at UT Southwestern Medical Center, where he was named “Most Outstanding Resident in Psychiatry” – an honor awarded to only one resident across all training levels each year.

“What I love most about this work is getting to know each person’s unique story and helping them find the right path forward. At Lighthouse, we believe everyone deserves access to expert, compassionate care that meets them exactly where they are in their journey – and that treating addiction effectively means treating the whole person, including the mental health conditions that so often accompany it.”

For ten years, Dr. Clark served on the faculty at UT Southwestern Medical Center, advancing from Instructor to Associate Professor while taking on increasingly significant clinical, research, and administrative responsibilities. His academic career was marked by leadership roles including Medical Director of the Inpatient Psychiatry Service and Director of the Interventional Psychiatry Service, along with extensive research into cutting-edge treatments for treatment-resistant mental health conditions. After leaving academic medicine in 2023, Dr. Clark shifted his focus to personalized, patient-centered care – combining the rigor of academic medicine with a more individualized approach. His expertise encompasses the comprehensive management of mood disorders, anxiety conditions, and psychotic disorders, with particular skill in treating patients with co-occurring substance use disorders. Dr. Clark’s unique background bridges the gap between cutting-edge research and compassionate clinical care, providing patients access to the most advanced treatment options including neurostimulation therapies and ketamine treatment, while ensuring that each person receives care that is both evidence-based and deeply personal.

The team at Lighthouse is exceptional, and it’s clear this work is a calling for them. Our son has grown and matured here, and we’re grateful he’s become part of such a supportive community.

The team at Lighthouse truly cared for my child as a person, not just a client, and kept me supported and informed every step of the way. They became an extension of our family, and I’m deeply grateful for everything they did.

The Lighthouse program is unique – it’s real life, tailored to your person, and supported by staff who have lived the struggle and believe in the fight. The engagement and confidence I’m seeing in my son is proof this is working.

The staff at Lighthouse communicates and functions as a team, from ownership to case managers to clinicians. Our son has found his joy again in sobriety, and the real-life model makes all the difference.

I came in struggling with addiction and had lost almost everything, but Lighthouse changed my perspective on life. The people here are top class and truly care about your health and wellbeing – I’m forever grateful.

From detox to recovery, Lighthouse was there every step of the way with a wonderful staff always available to answer questions. It was the best decision for my son, and I cannot recommend them enough.

As exhausted parents, we never imagined feeling so confident about our son’s care – but Lighthouse’s holistic approach changed that. They are an outlier among programs, and we would recommend them without reservation.

Lighthouse has been a blessing for our family – the combination of programs provided exactly what our son needed to commit to sobriety and maintain it. Recovery is hard work, and they are willing to do that work with you and your loved one.

Right away I could tell the staff truly care – they had been in my exact shoes and made me feel safe, secure, and supported. I made the closest relationships of my life through this program, and I can say it really is the right place.

The team at Lighthouse walked me through every step, and their personalized, firm but compassionate approach made all the difference. I’m so thankful for the care my loved one received and the trajectory their life has taken since.

We felt we had lost our son to drugs eight years ago, but after Lighthouse, he now has a job, an apartment, a car he saved for, and he’s calling to invite us to dinner. What can you say to someone who has given you back your son?

The beauty of Lighthouse is that they allowed me to experience real life – like getting a job – while still receiving long-term treatment in a loving, caring environment. This was my 7th treatment, and it’s the one that worked.

Our son had been in and out of treatment for over 10 years, but Lighthouse gave him the aftercare, community, and sense of self-worth he was missing. He’s now been sober almost a year – we have our son back, and he has his life back.

Peace is the first word that comes to mind when I think about Lighthouse – the staff understood exactly what my loved one needed, and I wholeheartedly believe this program saved his life.

Lighthouse’s comprehensive program was exactly what my son needed to get his life back on track and start believing in himself again. The homes are beautiful, and the staff truly care about the residents.

After researching several programs, we chose Lighthouse for its individualized approach – and our son built a strong foundation during his time there. He’s now thirteen months sober and back in college.

The next chapter starts at Lighthouse.
