Fishtown Medicine | Neighborhoods
Fitler Square feels like a village inside the city. You know your neighbors at the Farmer's Market. You spend weekends at Schuylkill River Park. You like Rival Bros for coffee and the small boutiques on Lombard. It is arguably the most community-focused pocket of 19103.
You do not want a corporate doctor. You want an internist who knows you. Fishtown Medicine is run by Ashvin Vijayakumar MD ("Dr. Ash"), a board-certified internal medicine physician you can text directly. Most visits happen by video. When you need an in-person exam, we come to your home.
What anchors your week in Fitler Square?
Fitler Square feels less like a Center City neighborhood and more like a small town tucked behind the Schuylkill. Our 19103 members move through it on foot, by name, and in patterns most of you have kept the same for years.
Schuylkill River Park and the trail. Saturday morning at Markward Playground while one parent picks up Rival Bros and the other watches the kid on the slide. The weekday runners on the trail at 6 am. The Sunday farmer's market at the Square. Most of our Fitler families orbit the park, and a lot of our quick check-ins happen by text from a bench while the kids are still busy.
The Lombard Street village. Rival Bros for coffee. The small boutiques on the 2200 block. Marathon Grill or High Street for the standing lunch. Neighbors knowing each other by name in a way that doesnt really happen on Walnut or JFK. We see a lot of repeat conversations with Fitler members because the same friends keep referring each other, and one good primary care relationship makes the rounds quickly.
The Fitler Club rhythm. A meaningful share of our Fitler members use the Club as a second living room. The Pilates studio. The dining room. The morning breakfasts before the office. Premium without the show. Thats the instinct we built the practice around.
The Fitler Square pattern is village-first, family-warm, and high-quality. Care should match that. We do not perform attentiveness. We are simply available.
Where do members go for labs and imaging?
Fitler Square is well covered:
- Quest Diagnostics at multiple Center City locations within walking distance.
- LabCorp on Walnut and at 30th Street Station.
- Mobile phlebotomy to your home.
For imaging, we send orders to Penn, Jefferson, or independent imaging centers.
Is this practice right for active runners on the Schuylkill?
Yes. Many of our Fitler members use the river trail daily. We support that engine:
- VO2 max guidance based on your watch data.
- Zone 2 training zones based on your actual heart rate.
- Iron and ferritin for endurance athletes.
- Lipidology and ApoB because endurance athletes can still have hidden cardiovascular risk.

Deeper Questions for Fitler Square Residents
I have a chronic condition (hypertension, anxiety, hypothyroidism). How does this work in 19103?
We manage most chronic conditions inside the membership: hypertension, anxiety, depression, hypothyroidism, GERD, prediabetes, lipids, IBS, and chronic insomnia. The change compared to traditional primary care is more time, more access, and continuity with one physician.
Are there health concerns specific to older Fitler Square rowhomes?
Yes:
- Lead paint and lead pipes in pre-1978 rowhomes and trinities. We can order a blood lead level, particularly if you are renovating or planning to conceive.
- Radon in basement-heavy older homes.
- Mold in slow-leaking roofs and damp basements.
What about air quality near I-76 and the Schuylkill Expressway?
I-76 borders the western edge of 19103. If you run on the river trail close to the road, particulate exposure is real. We talk about timing (early morning is generally cleaner) and route selection.
Is Fitler Square walkable enough for daily movement?
Walk Score in the 90s. The river trail, the Square itself, Rittenhouse, and the connector to South Street give you real options. We build movement plans that use them.
I am a young parent in Fitler. How does this fit?
Fitler is full of young families. Most parents we see in 19103 are running on empty because their kid's care is sorted but their own is not. Direct text access fixes that. Handle your blood pressure refill while pushing the stroller to the Square, not by waiting on hold.
I want longevity care, not just sick care. What do you offer?
Most Fitler members come for exactly this. The longevity layer:
- ApoB and Lp(a) for cardiovascular risk.
- Insulin sensitivity to catch metabolic dysfunction early.
- Hormones (testosterone, thyroid, cortisol).
- DEXA for body composition and bone density.
- VO2 max guidance.
I want an executive physical in Center City. Can I get one through this practice?
Yes. Our annual deep-dive includes advanced lipidology, hormones, insulin, body composition, VO2 max guidance, and a written 12-month plan. Most of it happens between video, your home, and one lab visit at Quest or by mobile draw.
How does Fishtown Medicine compare to a Penn primary care office?
Penn primary care is staffed by good doctors stuck in 12-15 minute slots. Same-day access is rare. We are direct primary care: long first visits, same-day text access, no rotating residents. We refer into Penn for specialty care.
Do you handle women's health?
Yes. From fertility optimization to perimenopause, we manage these directly and offer the nuanced care big systems often skip.
What about mental health? Therapy referrals?
We treat anxiety and depression directly with evidence-based medication management when appropriate, and we maintain a list of therapists in Center City we trust for talk therapy. We do warm referrals.
I am a Penn or Jefferson employee in Fitler. Does this work for me?
Many of our 19103 members are clinicians at Penn, CHOP, or Jefferson. Membership gives you a doctor outside your own system, with the privacy and depth that hospital-based primary care cannot deliver in 12 minutes.
