Hobbies & Interests

Dr. Hellman enjoys spending time with family, skiing, and horseback riding.

Fun Facts

The best advice Dr. Hellman has ever received is “It is better to do things right the first time instead of taking shortcuts and having to spend more time repeating it in order to get it right.”

The most exotic place she has visited is Ko Samui, a little island off the coast of Thailand.

Not everyone knows this about Dr. Hellman, but her favorite hobby is English-style horseback riding.

Her guilty pleasure is a full breakfast with her family on Sundays.

Dr. Hellman wanted to be a doctor for as long as she can remember. “I remember thinking that I wanted to ‘take care of babies’ that were sick in the hospital.”
