About Me

I’m a Harvard-trained academic cardiothoracic anesthesiologist and cardiovascular ICU critical care physician. I divide my clinical time between the OR and ICU caring for critically ill patients, training residents and fellows, and fostering multidisciplinary collaboration. I also enjoy creating and curating free, open-access medical education (“FOAMed”) to distribute through social media, investing, studying, teaching, and all things tech!

My clinical interests include ultrasonography, mechanical circulatory support, RV dysfunction, ICU pharmacology, and advanced monitors.

EchoTools is a product of trial-and-error that I've been piecing together since my fellowship training. It unifies my interests in medical education, ultrasonography, and programming in a way that can hopefully be helpful to many! I write 100% of the code, so if you have any feedback, let me know.

CA2 on my echo rotation! Thank you for creating and offering this app for as a free resource! I am very excited to show my attending tomorrow in the OR.

CA-1 on cardiac rotation. This app is great as a reference while in the OR! I like how there are labels on the TEE images to help orient me.

I use this app every time I need to double check normal values while reporting. Saves me so much time trying to scour ASE and Google for accurate up to date information.

Incredibly helpful app that I recommend to all training levels and specialties. My POCUS use has skyrocketed thanks to EchoTools. Whether periop or in the ICU, I use it more than any other medical app.

This is a work of art and, as a senior Anesthesiology/Critical Care Resident-Cardiac Anesthesiologist to be, I've used it since the first version both in the OR and CVICU.
