A Simpler Way to
Stay Healthy.

We've replaced the rushed feeling of traditional clinics with a deliberate, relationship-first process.

Direct-pay primary care. Insurance still covers your labs, imaging, and prescriptions.

Step 01

Is This Right For You?

Connecting with your Doctor

We start with a brief conversation. Whether you want to optimize your performance, find the root cause of an issue, or have a doctor who truly knows you, or get treatment right away, we are right there with you.

Step 02

Connect the Dots.

The 90-Minute Deep Dive

We take the time to understand not just your symptoms, but the underlying foundation of your health - energy, sleep, and lifestyle. Then we order advanced blood work to check your metabolic, immune, hormone, and heart health (not by strategy, but personalized to what's right for you).

We look at your body as a system, not just a list of symptoms. We find the small signals early, before they become serious problems.

“Dr. Ash is an incredibly thorough and knowledgeable physician. This level of care is so rare to find, and I couldn't be happier that I found him. He takes the time to get to know as much about his patients as possible, and is very responsive to questions. Couldn't recommend more highly!”

“When you are used to being treated like a faceless number in the medical system, it is incredible to connect with someone like Dr. Ash and see what medicine can be like. You don't actually have to dread going to the doctor; with Dr. Ash, you can even look forward to it.”

“Dr. Ash is truly phenomenal! He has been my ally with my recent serious medical crisis, checking in every few days, listening thoroughly to my symptoms, and taking the lead examining all the root causes. More than any other doctor I've worked with, he has restored hope for me!”

“Dr. Ash is the kind of person you know is looking out for you as a person. You're never a number to him. It's hard to picture a situation where you have to place greater trust in someone else to do the right thing.”

“I wish I could give 6 stars. I have never met a doctor so attentive, caring and thorough as Dr. Ash. Home visits are definitely uncharted territory for me but he made me feel comfortable every step of the way. Highly recommend.”

Frequently Asked Questions

No. No deductibles. No copays. No co-insurance. No visit fees. No initiation fees. No cancellation fees. Everything is included in the terms of your membership or package: unlimited access to Dr. Ash, consults, texts, video calls, all of it. Labs, imaging, and specialist referrals are ordered through your insurance. Pharmacy medications and treatments are subject to your plan's copay, co-insurance, or deductible.

Insurance is designed to cover 'Medically Necessary' care for existing diseases, but it rarely covers aggressive prevention. We bridge the space between both worlds. For our direct care (consults, texts, video calls), we function outside the insurance system to ensure you get the time and depth you deserve. For everything else - medications, labs, and imaging - we make your insurance work for you. Dr. Ash leverages his background in Internal Medicine and Value-Based Care to ensure your existing benefits cover your diagnostics while still maintaining Medicine 3.0 standards. Your membership is 100% HSA/FSA eligible.

The best time to protect your health is before things shift. We use our time together to establish deep baselines (metabolic, hormonal, immune, cardiovascular) and uncover the small signals and risk factors that matter most. We're not waiting for you to get sick; we're actively working to keep your health strong. If you're the type who'd rather get ahead of problems than wait for them, <a href='/packages' class='underline font-semibold'>this is exactly what our packages are built for.

Absolutely. We coordinate your care, send your records ahead of you, and - crucially - we debrief with you afterwards to translate the jargon. We often 'curbside' specialists for you, getting expert opinions without you needing to book a separate appointment unless a procedure is actually required.

Yes, and that's exactly what we're built for. Unlike some functional or integrative practices that only focus on one niche and send you to urgent care for everything else, Dr. Ash is a board-certified internist who handles the full picture. Sinus infections, back pain, blood pressure management, annual physicals, referrals, prescription refills, all of it. The difference is that we also go deeper: advanced diagnostics, preventive strategy, and the kind of proactive care that keeps you out of the ER in the first place. You're not choosing between a primary care doctor and a longevity-focused one. You're getting both.

Yes. Always. No catch. The introductory call is a real conversation with Dr. Ash, not a sales pitch, not a receptionist screening you. He'll ask about what's going on, what you've tried, and what you're hoping to find. If we're the right fit, you'll know by the end of the call. If we're not, he'll tell you that too. <a href='/#start' class='underline font-semibold'>Book your free call here.

We know how much you care about the people you love. While you can certainly initiate the process, proactive medicine works best when the patient is fully engaged. We encourage you to join them on the first introductory call so we can all get on the same page. If they feel comfortable and ready to take ownership, we can get them started immediately. We offer a partner/spouse discount.

We believe you should stay because you see value, not because you're trapped in a contract. There are no initiation or cancellation fees. Memberships (monthly, quarterly, or annual) renew automatically. If you cancel, your access continues through the end of the current billing cycle and you won't be charged again. Packages renew every 12 months to maintain continuity of care. You'll always have a link to <a href='http://fishtownmd.com/account' class='underline font-semibold'>manage your plan: upgrade, downgrade, or cancel anytime you want.
