The Woodlands, TX Ketamine Therapy Clinic: Science-Backed Treatment for Depression, Anxiety, PTSD, and Chronic Pain That Conventional Approaches Haven't Resolved
Ketamine therapy accessible to The Woodlands and the north Houston corridor. Board-certified anesthesiologist Dr. Ho leads every protocol at three Houston-area clinics. Open 6am–9pm, seven days a week.
Ketamine Therapy in The Woodlands, TX
Somewhere between the second failed antidepressant and the fifth, a realization forms that nobody says out loud: maybe the problem isn’t finding the right drug within this category. Maybe the category itself is the limitation. Every standard antidepressant — SSRIs, SNRIs, tricyclics, MAOIs, atypicals — works within the same neurochemical territory. They adjust serotonin, norepinephrine, or dopamine, then wait for the brain’s slow adaptive response. When that response doesn’t arrive after adequate trials of multiple medications, what you’re facing isn’t a failure of effort. It’s a pharmacological boundary.
Ketamine crosses that boundary. It operates through the glutamate system — the largest and most active signaling network in the human brain — and does something no conventional antidepressant was designed to do: it directly repairs the synaptic connections that chronic illness has physically degraded. The Depression and Bipolar Support Alliance (DBSA) recognizes treatment-resistant depression as a condition affecting up to one-third of people treated for depression and highlights the importance of newer treatment approaches for patients who haven’t responded to standard care. Catalyst Health & Wellness makes ketamine therapy accessible to The Woodlands community through three Houston-area clinics, each directed by Dr. Ho — a board-certified anesthesiologist and former pediatrician whose combined expertise provides the precision dosing, physiological monitoring, and compassionate care that this treatment demands.

Ketamine: From Operating Room Essential to the Most Significant Psychiatric Advance in a Generation
Ketamine’s credentials weren’t earned in a psychiatric research lab. They were earned in operating rooms, trauma centers, pediatric units, and combat field hospitals across six decades. Synthesized in 1962 and FDA-approved as a general anesthetic in 1970, ketamine has been used continuously on millions of patients — building one of the most thoroughly documented safety records in all of pharmacology.
The psychiatric discovery happened by accident. In the late 1990s, neuroscientists studying the glutamate system — responsible for the vast majority of excitatory signaling in the brain — observed something no existing antidepressant had ever produced: patients given sub-anesthetic ketamine doses experienced rapid, pronounced depression relief. Not over weeks. Over hours. And not in mild cases — in the patients who’d failed every other available treatment.
The science now explains why. Standard antidepressants boost neurotransmitter availability and rely on the brain’s gradual neuroplastic adaptation — a process that takes four to eight weeks when it works at all. Ketamine takes a fundamentally different path. It blocks NMDA receptors within the glutamate system, launching a biochemical cascade that releases brain-derived neurotrophic factor (BDNF) — the protein that physically builds new synaptic connections in brain regions governing mood, threat perception, and pain processing. Chronic conditions don’t merely affect your chemistry. They erode your brain’s physical wiring. Ketamine repairs that wiring directly. Because this structural damage is the common denominator across depression, anxiety, PTSD, OCD, chronic pain, and suicidal ideation, a single mechanism of repair can produce improvement across diagnoses that appear distinct on the surface but share the same neural substrate.

Two Administration Methods, One Therapeutic Objective
We match the delivery route to your clinical needs and personal comfort — not to convenience or assumption.

IV Ketamine Therapy
Intravenous delivery places ketamine directly into the bloodstream through a small catheter, providing continuous, real-time control over the infusion rate. Dose optimization happens instantly — a slight upward adjustment to deepen the therapeutic effect, a quick reduction to manage a transient response. That precision is why IV delivery remains the benchmark in ketamine research and clinical practice. Mood disorder sessions typically run 40 to 60 minutes.

IM Ketamine Therapy
Intramuscular delivery uses a single injection — typically in the upper arm or thigh — and bypasses IV access entirely. The medication absorbs through muscle tissue and produces the same core therapeutic effect. Patients who find IVs stressful, whose veins are challenging, or who prefer a simpler setup often choose IM. Full monitoring continues throughout in a private treatment room.
Both methods are clinically effective. We'll walk through the options during your consultation and help you choose based on your medical profile and personal preference — with no pressure in either direction.

Your Treatment Journey: Complete Transparency
No hidden steps, no vague timelines. Here's the entire process laid out clearly.
Step 1: Free Phone Consultation
Call (713) 772-5315. You’ll connect with someone who understands treatment resistance from deep clinical experience — not a scripted intake call. No referral. No insurance pre-authorization. No hoops.
We’ll cover:
- The full reality of your symptoms — how they affect your day, your relationships, your ability to function at the level you know you’re capable of
- Your complete treatment history, including medications that partially helped and ones that didn’t
- How ketamine therapy works, whether your profile suggests you’d benefit, and what honest results look like
- Full transparency about cost, scheduling, logistics, and timeline
- Every concern or question weighing on you
Free. No obligation. No pitch.
Step 2: Medical Intake
When you decide to proceed, we send a thorough intake questionnaire. This isn’t administrative — it’s the blueprint for your protocol. Every medication response, every physical health consideration, every symptom pattern feeds directly into the plan we build. We’ll also ask what meaningful improvement looks like for you specifically. Coordination with your existing providers is welcome and strengthens our decisions, but it’s never required.
Step 3: Your First Visit
Simple preparation:
- No food for at least 6 hours before
- Clear liquids in small amounts okay up to 2 hours prior
- Comfortable clothing
When you arrive:
- Full session walkthrough and remaining questions addressed
- Baseline vital signs recorded
- IV placed or injection site prepared
Dr. Ho developed his needle skills in pediatrics — placing IVs in children who needed extraordinary care and gentleness. That technique transfers directly to adults who feel nervous about the process. He uses the smallest practical gauge needle, offers topical numbing cream before skin contact, and keeps portable ultrasound ready for difficult veins. Nearly every patient says the needle was what they feared most and noticed least.
Step 4: The Session Itself
You’ll recline in a padded chair in a private room built for comfort:
- Noise-cancelling headphones with calming audio
- A soft eye mask
- A warm blanket
- Lighting you control
Duration depends on condition:
- Mood disorders (depression, anxiety, PTSD, OCD): approximately 40 minutes of treatment plus 20 minutes of recovery
- Chronic pain conditions (fibromyalgia, migraines, EDS, AS pain, complex pain): approximately 4 hours of treatment plus 2 hours of recovery
The extended pain protocol provides the sustained NMDA blockade required to meaningfully disrupt central sensitization — the nervous system amplification that perpetuates pain long after original tissue healing.
Continuous vital sign monitoring. Dr. Ho or a clinical team member stays present, checking in regularly. First-session anxiety is universal and nearly always resolved once patients experience how calm and controlled the environment actually is.
Step 5: Post-Treatment Recovery
After treatment, you’ll rest while the effects gently clear. Most patients feel oriented and steady within 20 to 60 minutes.
Key details:
- You cannot drive — arrange a ride before arriving
- Plan a quiet rest of the day, ideally with someone you trust nearby
- No major decisions, strenuous activity, or machinery until the next morning
- Our team will check in by phone that evening or the following day
Serious adverse effects at our sub-anesthetic doses are uncommon. Our team stays reachable whenever you need reassurance.
Step 6: Your Ongoing Treatment Plan
Ketamine response is highly individual. Some patients experience a clear shift after one session. Others build progressively across several. Both timelines are normal.
The typical framework:
- Initial series: 6 sessions over 2 to 3 weeks for mood conditions
- Dose refinement between sessions guided by your unique response
- Maintenance schedule tailored to your trajectory — weekly, biweekly, or monthly
- Reassessment at every visit to keep the protocol current with your progress
This plan is dynamic. It responds to your data, your experience, and the evidence each session generates.
Clinical Evidence Supporting Ketamine Therapy
Ketamine’s credibility rests on decades of controlled, peer-reviewed research from world-leading institutions — not preliminary findings or anecdote.
The foundational NIH trial demonstrated a 71% response rate in treatment-resistant depression after a single ketamine infusion, versus 0% with placebo — the widest efficacy gap ever recorded in a controlled psychiatric medication study (Zarate et al., 2006).
A rigorous multi-center replication using an active placebo to account for sedation effects confirmed a 64% response rate within 24 hours versus 28% in the control group, producing a number needed to treat of just 2.8 (Murrough et al., 2013).
A groundbreaking Science publication mapped the mechanism: ketamine directly reverses the synaptic damage chronic stress inflicts, driving new neural connection growth in the prefrontal cortex within a single day (Li et al., 2010).
For PTSD, a controlled trial at the Icahn School of Medicine at Mount Sinai found that repeated ketamine infusions produced sustained, clinically significant symptom improvement, with approximately two-thirds of participants achieving clinical response (Feder et al., 2014).
The Woodlands Township — a community of over 120,000 residents built within a natural forest, consistently rated among the best places to live in America — is a place where families approach decisions with intelligence and deliberation. This body of research meets that standard completely.
What the evidence consistently shows:
- Ketamine engages the glutamate pathway — completely separate from the serotonin, norepinephrine, and dopamine systems every standard antidepressant targets
- Treatment-resistant depression response rates of 60-71% far exceed the 10-15% typically achieved by switching between conventional medications
- Synaptic regrowth begins within hours, verified by neuroimaging — the fastest structural brain repair documented for any psychiatric intervention
- The same neural restoration mechanism simultaneously benefits depression, anxiety, PTSD, OCD, chronic pain, and suicidal ideation

Begin Ketamine Therapy Near The Woodlands, TX

Your brain didn’t refuse those medications because something is wrong with you. It refused them because they were speaking to the wrong system. Serotonin, norepinephrine, dopamine — those are three of the brain’s communication channels. The glutamate pathway, where chronic illness physically degrades the connections that mood regulation, emotional processing, and pain management depend on, is the fourth. Ketamine speaks directly to it. It doesn’t nudge chemistry and hope for slow adaptation. It rebuilds synaptic connections — often within a single session — and lets the structural repair produce the clinical improvement.
Call (713) 772-5315. Tell us what you’ve been through — the diagnoses, the medications, the frustrations, the outcomes you haven’t given up on. We’ll provide an honest, no-cost assessment of whether ketamine therapy makes sense for your clinical picture, explain every detail of the process, and let you decide without pressure.

Commonly Asked Questions
Get Help NowWhat's the typical timeline for noticing improvement with ketamine?
Many patients notice improvements within hours of their first treatment, though some people need a few sessions before experiencing the full benefit. This rapid action is one of ketamine’s most remarkable qualities, especially compared to traditional antidepressants that can take 4 to 8 weeks to work.
How does Catalyst ensure patient safety throughout ketamine treatment?
Yes, when administered by trained medical professionals in a controlled setting. Ketamine has been used safely as an FDA-approved anesthetic for over 50 years. Dr. Ho’s expertise as an anesthesiologist ensures the highest safety standards. We monitor your vital signs throughout treatment, and serious complications are rare.
What does a full ketamine treatment program look like?
Most patients receive an initial series of six treatments over two to three weeks. After that, you’ll likely need maintenance treatments to sustain your improvements. The frequency varies based on individual response. Some people return every few weeks, while others maintain their benefits with monthly treatments. We’ll work with you to find the schedule that keeps you feeling your best.
How would patients describe the experience of a ketamine session?
Experiences vary from person to person. Many patients describe feeling relaxed, peaceful, or slightly disconnected from their surroundings. Some people have visual or sensory experiences, while others simply feel calm. These effects are temporary and subside as the ketamine wears off. Most patients find the experience pleasant and therapeutic.
What should I arrange ahead of time for treatment day?
No, you cannot drive yourself home after ketamine treatment. You’ll need to arrange transportation. By the time you leave our facility, you’ll feel much clearer, but for your safety, you should not drive, operate heavy machinery, or make important decisions for the rest of the day.
How durable are the benefits between ketamine treatments?
This varies considerably between individuals. Some people maintain their improvement for weeks or even months after their initial series. Others need more frequent maintenance treatments. During your follow-up appointments, we’ll assess how you’re responding and adjust your maintenance schedule accordingly.
Is it safe to receive ketamine while on other psychiatric medications?
In most cases, yes. Ketamine typically works well alongside other psychiatric medications. However, we’ll review your complete medication list during your consultation to ensure there are no contraindications. Never stop taking prescribed medications without consulting your prescribing physician.
Do I need a doctor's referral or insurance approval before starting?
No, you don’t need a referral to begin ketamine therapy at Catalyst Health & Wellness. However, communication with your current healthcare providers can be helpful, and we encourage coordination of care whenever possible.
