A new practice with immediate availability. The panel is open, appointments are same-day or next-day, and no referral is needed — you do not need permission from an insurer or another doctor to be seen here. Walk-in clinic hours are Tuesday through Thursday, noon to 8 pm, and Saturday, 9 am to 5 pm, and a virtual doctor consultation by video is available anywhere in California.
Medicine without the middleman
Phil Zhou Medical is a cash-only medical practice built for busy professionals, business owners, parents, and anyone who is tired of fighting for their own healthcare. You pay one clear price, you see the doctor, and you leave knowing exactly what it cost.
I do not bill insurance. That single decision removes the prior authorizations, the coding games, the surprise bills six weeks later, and the seven-minute visit. What is left is the part that actually helps you get better: time with your physician.
Before medicine, I worked at Amazon. What stuck with me was how seriously they took speed and convenience — how much work went into removing small frictions most businesses never notice. Healthcare runs the other way. The friction is the system.
I am building the other version of that for my own community. You are a patient, and you are also a customer, and there is no good reason those should feel like different things. Most prescription refills here take one text message — no portal, no phone tree, no appointment to ask for something routine. (Membership required.)
- Call or text your doctor directly — not AI, not outsourced to a 3rd party
- Real appointment lengths — however much time is needed
- Transparent pricing — $150 a visit, or $99 a month
- labs, imaging, and medications passed through at cost for cash-payers
- Same-day and next-day availability

Why patients choose Phil Zhou Medical
Peace of mind
When something is wrong, you text your doctor and your doctor answers — not a triage line, not a portal message returned in four days.
Open at lunch, after work, and Saturdays
Clinic hours Tuesday through Thursday, noon to 8 pm, and Saturday, 9 am to 5 pm — room for a lunch-hour visit, one after work, or one on the weekend, and a phone answered 24/7. No taking a day off to see a doctor.
Thorough, personal care
Thirty to sixty minutes means I get to the actual problem instead of managing the clock.
Lower, predictable cost
One flat price per visit or per month. No copays, no facility fees, no bill that shows up later.
Better outcomes
Prevention, early intervention, and follow-through — the things that keep you out of the hospital.
Evidence-based and relationship-driven
Careful, current medicine delivered by a physician who knows your history without opening a chart.
What I do
Weight loss
$200 a month, everything included, and a physician adjusting the dose with you rather than on a calendar.
Headache & migraine
Neurology-trained care, from the first workup to a preventive plan that actually holds.
Insomnia
A real plan to fall asleep faster and sleep through the night — starting with why you are not.
Anxiety
Treated medically and without a waitlist, by a physician you can text when a new medication does not feel right.
Depression
Medication, follow-up in weeks rather than months, and a referral to therapy when it will help. More
Men’s health
Stronger, longer-lasting erections, and low testosterone diagnosed properly — discreetly, by a doctor you can text.
Women’s health (HRT)
Menopause and perimenopause care with time for the history, and FDA-approved hormone therapy when it fits.
Addiction medicine
Alcohol, opioids and nicotine, treated as the medical problems they are — and nothing is billed to an insurer.
Back & shoulder pain
An exam, injections in the office, and a plan aimed at getting you moving rather than just medicated.
Walk-ins and everyday problems are seen too — colds, infections, minor injuries, physicals. What that looks like.
The whole arc of a life
Some practices are built for one kind of patient. This one is built for the long relationship — the annual physical in your thirties, the blood pressure that starts creeping in your fifties, and the hard conversations that come much later.
Having practiced in hospice, I know what it looks like when nobody was paying attention early. That is most of why this practice exists.
Simple pricing
$150
Per office visit
Pay as you go. No membership required, no insurance needed, price known before you walk in.

VIP membership
24/7 direct contact with your physician, plus routine care and refills handled without an office visit.
$200 / month
Weight loss program
Everything included — one flat monthly price, no add-ons. How it works
“DPC cash-pay docs have been cheaper to see annually than paying a single month of my insurance premium.”
— what patients tell me
No insurance is billed — not any plan, not Medicare, not Medi-Cal. Payment is due at the time of service by credit or debit card, HSA or FSA card, cash, ACH, Zelle, PayPal, or cryptocurrency.
