Healthcare That Finally Hears You
Tired of feeling rushed, unheard, and navigating a confusing healthcare system alone? At Fishtown Medicine, we believe you deserve better. We're bringing back the personalized doctor-patient relationship, reimagined for modern life. It's time for a healthcare partner who truly knows your story, shares your goals, and gives you the attention you deserve.
Meet Dr. Ash: Your Partner in Proactive Health
I’m Ashvin Vijayakumar, MD (“Dr. Ash”). I’m a board‑certified Internal Medicine physician dedicated to personalized, preventive care. I founded Fishtown Medicine to create a space where patients are seen, heard, and cared for with genuine focus.
I combine over a decade of experience in primary care with leadership training from Mount Sinai to help you navigate today’s complex healthcare system. Your plan reflects your unique story, labs, family history, and wearable data—and it moves at a pace that feels safe and doable for you.
“I believe health is a dynamic state shaped by the connection between body, spirit, community, and environment. Every person’s health story is unique and deserves personalized attention.”
As a Fishtown resident, I'm more than just your doctor; I'm your neighbor. When I’m not in the clinic, you can find me rock climbing, biking, or camping with my wife, son, and two cats.
The Fishtown Medicine Difference:
Care Designed for You
Forget the old model. Our direct primary care (concierge) approach is built around your life, giving you unprecedented access and a deeper focus on prevention.
Time to Talk: Your appointments are 30 to 90 minutes long. We have the time to dive deep into your health history, answer every question, and build a plan together.
Direct Access, No Delays: Reach Dr. Ash directly via HIPAA-secure text, voice, or video. Get same-day responses without navigating phone trees or endless patient portals.
Proactive Partnership: We don't just treat symptoms; we work to prevent illness before it starts. Our goal is to move you from a reactive state to one of proactive wellness and longevity.
Precision & Personalization: We blend the best of conventional medicine with cutting-edge tools like advanced imaging, genetic testing, and wearable health data to create a care plan that is 100% unique to you.
-
We begin with a complimentary 15-30 minute consult to confirm fit and goals. This is a chance for you to share your health concerns and for us to see if we're a good fit—there's no pressure. Your first comprehensive visit is typically 60–90 minutes.
-
Since 2014, in primary and preventive care as a physician and medical director across group and hospital settings. I collaborate with nutrition, mental health, and genetics professionals when helpful.
-
Prevention comes first. I work to identify risks early and help you lower them—addressing metabolic and cardiovascular health, blood pressure control, early diabetes prevention, autoimmune risk, and healthy hormone transitions—using your history, labs, genetics, wearable data, and goals.
-
If it feels like a good fit, we’ll review transparent pricing and next steps. You can text follow‑up questions anytime.
-
Yes. We don’t bill insurance for visits; HSA/FSA and credit cards are accepted. We use your insurance for labs, imaging, and referrals.
-
Most care begins with a secure text. We reply the same day during business hours; urgent concerns are triaged sooner. You can schedule video, phone, or in‑home as appropriate. Standard visits last 60–90 minutes; extended visits are available when needed. For emergencies, call 911.
-
Only tests that change decisions. Examples may include metabolic panels, inflammatory markers, hormones, advanced lipid markers (ApoB, lipoprotein (a), NMR), selective genetics when indicated, personalized imaging based on risk, and age‑/family‑history‑aligned cancer screening. We’ll review benefits, risks, and costs before ordering.
-
When the evidence supports it and it fits your goals. We use shared decision‑making to personalize care while staying safety-first.
