Okay, let’s tackle this. So Romi Bloom has a strong educational background from Harvard Medical School, which is a top-tier institution. He also has skills in dermatology, clinical research, and medicine, which are in demand. Location is Northbrook, Illinois, which is a suburban area with a decent cost of living. Dermatologists with his level of education and skills can charge higher rates. According to the Bureau of Labor Statistics, the median annual salary for dermatologists in the US is around $621,000, which translates to around $300-$400 per hour. However, considering his expertise and education, I would estimate his hourly rate to be on the higher side, around $250.
