Mark's Life and Interests

Mark Derho Owner Bike Rent Puerto Rico

Mark's Life in Puerto Rico

Over three years as an executive consultant, I led the team and efforts in securing a $60M 6-year RFP contract and managed Bike Rent NYC. I relocated to San Juan in 2019 and opened my storefront business: Bike Rent Puerto Rico. I planned to continue to work with my most reliable website and digital marketing retainer clients, and, manage the bike rental business simultaneously. 

Bike Rent Puerto Rico

Six months after opening the pandemic shut down the bike rental business to the public for months, and, eliminated my NYC client’s need for remote work. The store reopened however the clients never recovered from the pandemic. Then came the flood of dockless e-scooters and e-bikes, essentially ending the bike rentals. I pivoted to offering kayak rental, and finally, the landlord tripled the rent and put the store up for sale. I closed the business in 2022.


About My Daughter Jessa

She decided she would no longer eat meat or any animal products at seven years of age.

She decided at 12 there were too many “Jessica’s”, so she changed her name to Jessa.

She liked working with adult tools and in the yard.

We built a 10′ x 10′ shed and she did most of the work, at 12.

She found real love, his name was Greg and he was an amazing young man and health professional.

She and Greg traveled the world together in spite of her illness,
Japan, Ireland, England, Auatralia, France, and more.

She designed the clothing and organized fashion shows in high school and college.

She was a fashion designer,
She designed the “Windows of the World” for Macys on 34th Street in NYC.

She was Columbia Hospital’s key note speaker after her first operation
and in TV and Mass-media promoting the hospital.

She raised money and awareness for organ transplant in New Jersey
through GoFund Me and sponsored events for NJ Organ Donors

She is no longer with us.

She died of infections after her second lungs transplant operation.

My dog Luno Moondog at the beach.

My friend Maria found him in Trujillo and brought him to me in 2022.

He had been abused and could only walk on two front legs.

Has was starving and we determined that he had a cancerous intestinal tumor.

He beat the odds again and survived the operation.
