Ketamine therapy for Missouri City and the southwest Houston corridor. Board-certified anesthesiologist Dr. Ho directs every protocol at three Houston-area locations. Open 6am–9pm, seven days a week.
Ketamine Therapy in Missouri City, TX
At some point, the pattern becomes unmistakable. Medication one didn’t work. Medication two produced side effects you couldn’t tolerate. Medication three offered partial improvement that plateaued after two months. Medication four was medication one at a higher dose, combined with something new. And somewhere in that cycle, the question shifts from “which drug should we try next?” to “is there something fundamentally different available?”
The answer is yes — and the reason it exists comes down to a limitation in the medications themselves, not in you. Every conventional antidepressant works within the same pharmacological corridor: serotonin, norepinephrine, dopamine. These are valid targets, and they help the majority of patients. But for the roughly one-in-three people whose depression, anxiety, PTSD, or chronic pain hasn’t responded, the issue is structural. Chronic illness degrades the physical synaptic connections between neurons in brain regions responsible for mood, emotional regulation, and pain processing. No drug designed to adjust chemical messenger levels can rebuild those connections. Ketamine can. It operates through the glutamate pathway — the brain’s most extensive neural communication network — and initiates rapid synaptic restoration in the very regions that chronic conditions have eroded. Penn Medicine describes ketamine-derived treatment as one of the most significant psychiatric advances in decades, providing relief within hours rather than weeks and offering a genuinely new mechanism of action after a long drought of innovation. Catalyst Health & Wellness brings this treatment to Missouri City through three Houston-area clinics, each led by Dr. Ho — a board-certified anesthesiologist and former pediatrician whose dual expertise covers the precise pharmacological management, real-time monitoring, and compassionate patient care that ketamine therapy demands.

Ketamine: How a Surgical Staple Became Psychiatry's Most Important Discovery in Decades
Ketamine’s origin story has nothing to do with mental health. It was created as an anesthetic — synthesized in 1962, FDA-approved in 1970, and immediately adopted by surgical suites, emergency rooms, pediatric units, and military field hospitals around the world. Over fifty years and millions of administrations later, its safety profile ranks among the most comprehensively documented of any medication still in active use.
The psychiatric chapter was entirely unexpected. In the late 1990s, scientists studying the glutamate system — the neural network carrying the majority of the brain’s excitatory signals — observed that low-dose ketamine produced something no antidepressant had ever achieved: rapid, substantial depression relief in patients who’d exhausted every other option. The improvement arrived in hours, not weeks. And the patients who responded most dramatically were precisely those whom conventional treatments had failed.
Two decades of research have since explained the biology. Standard antidepressants boost the availability of serotonin, norepinephrine, or dopamine and then wait — four to eight weeks, typically — for the brain to gradually adapt. Ketamine doesn’t wait. By blocking NMDA receptors within the glutamate system, it initiates a molecular cascade that releases brain-derived neurotrophic factor (BDNF), the growth protein that physically constructs new synaptic connections in regions governing mood regulation, threat processing, and pain modulation. Chronic depression, anxiety, trauma, and pain don’t just change how you feel. They structurally thin the neural architecture your brain relies on. Ketamine rebuilds that architecture — often within a single treatment. This shared structural deficit across conditions is why ketamine simultaneously improves depression, anxiety, PTSD, OCD, chronic pain, and suicidal thinking.

Ketamine Delivery: Two Proven Routes
Same therapeutic destination. Two paths to get there. We match the method to your clinical needs and personal comfort.

IV Ketamine Therapy
Intravenous delivery introduces ketamine directly into the bloodstream via a small catheter, providing your clinician continuous, real-time dosing control. Adjustments are instantaneous — fine-tuning the therapeutic window or managing a temporary side effect happens without any delay. That level of responsiveness is why IV remains the reference standard in ketamine research and clinical practice. Mood disorder sessions generally run 40 to 60 minutes.

IM Ketamine Therapy
Intramuscular delivery uses a single injection — typically the upper arm or thigh — eliminating the IV entirely. The medication enters the bloodstream through muscle tissue and generates the same core therapeutic effect. Patients who prefer to skip IV access, whose veins are difficult, or who want a streamlined experience often gravitate toward IM. Full monitoring continues in a private treatment room throughout.
We'll discuss both during your consultation and help you choose based on medical factors and personal comfort — no pressure toward either option.

Your Treatment Path: Transparent From Start to Finish
No ambiguity, no vague timelines. Here's what happens at every stage of ketamine therapy at Catalyst.
Step 1: Free Phone Consultation
Call (713) 772-5315. You’ll reach someone who understands treatment-resistant conditions from years of clinical experience — not from a scripted intake form. No referral necessary. No insurance pre-authorization. No barriers.
We’ll walk through:
- What your symptoms actually do to your daily life — the full picture, not the clinical shorthand
- Every medication and therapy you’ve tried, including what worked partially and what failed entirely
- How ketamine therapy works, why it’s different, and whether your clinical profile makes you a strong candidate
- Clear details on cost, scheduling, and what realistic improvement looks like for your specific situation
- Every question or hesitation you need addressed before making a decision
No cost. No obligation. No agenda except giving you the information you need.
Step 2: Medical Intake
When you’re ready, we send a comprehensive intake questionnaire. This isn’t busywork — it’s the blueprint for your individualized protocol. We’ll ask about medication responses (effective and otherwise), your physical health profile, symptom timing and triggers, and what progress would genuinely look like within the context of your actual life. Coordination with your current providers is always welcome and sharpens our clinical decisions, but it’s never mandatory.
Step 3: Your First Visit
Preparation is straightforward:
- No food for at least 6 hours before treatment
- Clear liquids in small amounts okay up to 2 hours prior
- Comfortable clothing
When you arrive:
- Complete session walkthrough and any remaining questions addressed
- Baseline vital signs recorded
- IV placed or injection site prepared
Dr. Ho built his needle technique in pediatric medicine — years of placing IVs in children who needed gentleness above everything else. That skill translates seamlessly to adult patients who feel nervous. He uses the smallest practical gauge needle, offers topical numbing cream before any skin contact, and keeps portable ultrasound available for challenging veins. The needle is nearly always what patients fear most and notice least.
Step 4: The Session Itself
You’ll settle into a padded recliner inside a private room designed for comfort:
- Noise-cancelling headphones with calming audio
- A soft eye mask
- A warm blanket
- Adjustable lighting under your control
Session length 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, sickle cell 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 engage central sensitization — the neural amplification that perpetuates pain far beyond the original tissue pathology.
Continuous vital sign monitoring throughout. Dr. Ho or a clinical team member stays present and checks in regularly. First-session anxiety is universal — and nearly always replaced by surprise at how calm and controlled the experience is.
Step 5: Post-Treatment Recovery
After treatment, you’ll rest while the effects gradually clear. Most patients feel grounded and clear-headed within 20 to 60 minutes.
Key logistics:
- You cannot drive home — arrange a ride before arriving
- Keep the rest of the day quiet, 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 carefully calibrated sub-anesthetic doses are uncommon. Our team remains reachable by phone whenever you need reassurance.
Step 6: Your Ongoing Treatment Plan
How quickly ketamine works differs from person to person. Some patients experience a marked shift after their first session. Others see improvement accumulate across several treatments. Both patterns are normal and expected.
The standard framework:
- Initial series: 6 sessions spread across 2 to 3 weeks for mood conditions
- Dose refinement between sessions guided by your individual response data
- Maintenance schedule adapted to your results — weekly, biweekly, or monthly
- Reassessment at every visit to keep the protocol aligned with your evolving needs
This plan isn’t static. It responds to your data, your feedback, and the clinical evidence generated by each treatment session.
The Evidence Backing Ketamine Therapy
Ketamine’s psychiatric credibility is grounded in decades of controlled, peer-reviewed research from some of the most respected institutions in medicine.
The pivotal NIH trial demonstrated a 71% response rate in treatment-resistant depression after a single ketamine infusion, compared to 0% with placebo — the largest efficacy gap ever documented in a controlled psychiatric drug study (Zarate et al., 2006).
A multi-center replication using an active placebo to control for sedation effects confirmed a 64% response rate within 24 hours versus 28% in the control arm, yielding a number needed to treat of 2.8 (Murrough et al., 2013).
A publication in Science revealed the mechanism: ketamine directly reverses the synaptic damage caused by chronic stress, stimulating measurable 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 reduction, with approximately two-thirds of participants reaching clinical response (Feder et al., 2014).
Missouri City — a community spanning Fort Bend and Harris counties, consistently recognized among the best places to live in the Houston region — is a city where families weigh decisions carefully and expect solutions backed by substance. This research provides exactly that.
What the evidence consistently establishes:
- Ketamine acts through the glutamate pathway — entirely separate from the serotonin, norepinephrine, and dopamine systems every conventional antidepressant targets
- Treatment-resistant depression response rates of 60-71% far surpass the 10-15% achieved by switching between standard medications
- Synaptic regrowth begins within hours, confirmed by neuroimaging — the fastest structural brain repair documented for any psychiatric treatment
- The same neural restoration mechanism simultaneously benefits depression, anxiety, PTSD, OCD, chronic pain, and suicidal ideation

Running out of medications in the same class isn’t the same as running out of options. The serotonin, norepinephrine, and dopamine systems those drugs targeted were one lane of brain chemistry. The glutamate pathway — where chronic conditions physically erode the synaptic connections that healthy function depends on — is another lane entirely. Ketamine enters it directly. It doesn’t adjust levels and wait for gradual adaptation. It constructs new neural connections, often within a single session, and lets the structural repair drive the clinical improvement.
Call (713) 772-5315. Share your history — the diagnoses, the treatments, the outcomes you’re still hoping to find. We’ll provide an honest, no-cost assessment of whether ketamine therapy fits your clinical picture, explain every step of the process, and let the decision remain entirely yours.

Commonly Asked Questions
Get Help NowHow soon after my first ketamine session might I feel improvement?
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.
What safety measures does Catalyst follow during 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.
How many treatments are included in a standard ketamine therapy plan?
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.
What is it like to undergo a ketamine treatment 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 do I need to plan for on treatment day regarding transportation?
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 long can I expect the improvements from ketamine to hold?
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.
Will ketamine therapy interfere with any of my current prescriptions?
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.
Can I begin ketamine therapy on my own, or do I need a referral?
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.
