I delivered a catered lunch to this office 2- 3 course meals which feeds up to 24 people. I work for a 3rd party company. On a catered delivery I drive to the restaurant, using my own insulated bags, pack the food and deliver to the address provided by a Jessica Roth. This delivery took 1 hour and 27 minutes. The lunch included 48 big pieces of chicken, rice, beans, churros, guac, sauces, plates, utensils, and napkins. I get to the office and because the food was more than what the person can carry I helped deliver to the break room and unloaded the items from my delivery bag. I say thank you and walk away and confirm the delivery. I look down on my phone and it reads CUSTOMER TIPPED $0 DOLLARS I have been working for this company for 8 years and in the & years I have yet to come across a drs office that left a $0 tip until yesterday with this office. I called and asked if something happened or if I did something to receive $0 for the work. They told me it was probably an oversight and the will make sure to fix the issue. I said thank you and left it at that. Mind you, in order to leave a $0 tip you have to click custom tip, then delete the recommended tip, and then enter $0. So I knew they were lying. At this point it is not about the tip but the utter disrespect from this office staff to the people bringing them their lunches and the person in charge of the ordering. I have given them 2 days to fix the issue and they have not. If this is how they treat the workers that feed them, I will most definitely tell everyone that this is not a place to go for your medical needs. They will probably rip you off as well. Your office should be ashamed of yourself for how you treat the workers that feed you.

I have been interaction with doctors from RDH for well over 20 years. The first being Dr. Henna HOSA who was my grandmothers doctor when she was diagnosed with pancreatic cancer. His bedside manner should taught in classes it was unbelievable. The combination of honesty and compassion was exemplary. I personally have had nothing but good experiences. I have EOE and have seen a few different doctors and they have been great.
