A bit of a drive to get to Venango Dept of Health (DOH) today to do Tb clinic but always a pleasure to work with the staff there.

Some facts about a disease we have all heard about but know so little:

-latent Tb infection (LTBI) cannot be transmitted
-there is a 10% lifetime risk of conversion into active Tb in otherwise healthy individuals (30% risk in diabetics; approaches 100% in immunocompromised)
-treatment of LTBI is optional and reduces risk by ~95% of baseline risk but does not completely eradicate it
-when Tb testing comes back positive, DOH gets notified. An investigation is done and Tb physician determines whether it’s active or not. For Northwest district of PA, that happens to be me.
-treatment and monitoring of Tb is provided for free by DOH, made possible by a team of physician, nurses and outreach educator working together.

Today was first day doing disability benefits assessment (DBAs) for veterans (STEEP learning curve).

Apparently they all live a few minutes from my office in Bradford, and would have had to travel to Erie otherwise. Rushing back to Warren for afternoon patients doesnt seem so bad knowing I was of some help* to our country’s heroes. 🇺🇸

Thank you for your service, Veterans. An honor to give back in a small way.

*Addendum: Credit goes to Dr Tahara for kindly allowing his office to be used to conduct DBA’s.

In commemorating what the practice’s namesake, Michael John Arnum, would have wanted, free clinic hours is being held from 1 to 5 today.

UPDATE 930 p:
Thank you for the great show of support today. We get busy phone calls day or busy visits day but never both. I appreciated all those who called to establish as patients today. You’re in capable hands.

Feeling grateful. It was surprisingly gratifying to help a sick patient today for a completely unplanned visit.

Patient was new to me. There was a concern of a respiratory infection. Glad they sought help, which otherwise would be delayed due to hectic work schedule.

UPDATE, 7 pm: make that two patients; yah, i’m a bona fide workaholic.

I am disturbed and disappointed beyond words at what transpired today. It’s a sad day to feel unwelcome and spoken to like I am not even human.

Yes, I was born abroad and came to this country at the age of 4. I worked hard and was ecstatic I got accepted into MIT, having been gaslit I wasnt good enough. At 19, I became naturalized. America has done so much for me and my family, I have always dreamt of giving back. Combining my love for science and interaction with people was how I decided on a career in medicine.

Fast forward through med school and residency.

Corporate medicine was restrictive in what I could do so I opened a practice much sooner in my career than I had intended. Such an endeavor required an immense level of hard work and discipline but in a county with no internist and I happen to be one, I wanted to be of service.

It’s disheartening how someone who has never met me would say such hurtful things purely based on my names sounding unAmerican. Having lived in America for 35 years, I identify as a Vietnamese American.

-Dr Le

UPDATE (6:48 Am, 10/23/25): Thank you for the overwhelming support from the community. It means a lot and I’m very grateful and appreciative that people chose not to silently look on as a fellow human being is being bullied.

Calling out an action as wrong is enough. We know nothing else about the person, so going on to remark she must be an idiot or lowlife or jealous, etc… is making needless assumptions about someone who may actually be a nice and sweet person (though clearly a racist). Please lead by example and give her the benefit of the doubt that she did not grant me.

The concept of “patient noncompliance” has always been troubling to me, as patients always have a compelling reason why they are not following treatment, with the reality being that the physician failed them in some way (didnt explain well enough being the most common offense, or didnt listen to their concerns and appropriately reassure them). A patient HAS to understand and believe the treatment will help them and that the benefit outweigh the harm or they will never agree to it.

^moral of seemingly irrelevant tangent: It’s never that black & white, and we shouldn’t be so quick to judge.

Many aren’t aware I also see patients at a branch location in Bradford, PA, 1 to 2 days a week, Thurs and/or Friday. It’s an office I share with another physician who isn’t there on the days I am. Here’s a tour of the location.

Story Behind the Practice’s Name

In 2023, the practice’s namesake — Michael J. Arnum — collapsed and passed away suddenly at the age of 54. The medical office was created in his honor and memory, to serve as a place patients can always rely on — just as Michael was there for everyone around him.

Michael was known for his boundless generosity. He gave his time freely to friends, family, and community — volunteering at churches, Scandinavian fairs, and Sons of Norway events. No matter how busy or tired he was, Michael’s response to someone in need was always the same:

“I’ve got you,”.

When I needed a place to stay, he was there. When I needed to get from Boston, MA to northwestern PA for a job interview, he was there. I’ve never known anyone more selfless and felt it was befitting that his legacy lives on through the practice.

Through rain and shine, he’d comfort people with his smile and unshakeable composure. The only time I was ever hospitalized, an otherwise distressing experience was uplifted by his unannounced visit. This inspired me to be there for my patients - in the ER, medical floor, or specialist’s visit - whenever I can.

Any constructive criticism is welcomed ; ultimately the colorful feedback I received a little while back did motivate me to tidy up the office. No one should be at an office they would be embarrassed to recommend to a family or friend.

As a practice serving the community, I want input on what you want in an ideal practice? (Something other than “A doctor who listens and care and doesn’t rush through an appointment” as it already comes up a lot.) This will help set my goals over the next few years of what I should aim towards.

Thank you,
Dr Le

This story broke my heart because I would love to take care of someone as sweet and health-conscious as she is. (Spoiler alert: the ad worked and a few physicians reached out to her).

Notice how she’s *only* (sarcasm) been a few years without routine care. The longest any of my patients has gone without seeing a doctor is over 20 years. 🤦🏻‍♂️

If you or anyone you know may be in a similar predicament, I would love to take on new patients who needs routine monitoring.

Solo private primary care practice providing medical service for patients age 18 up. Treat both chronic and acute illnesses. Accepting new patients. Walk in welcome.

This should help bring visibility to an otherwise rather obscure building. 😅
