Peninsula Doctor Concierge Medicine 401 Burgess Drive, Menlo Park, CA 94025

"The best doctor relationship I have ever had! Dr. Hiroshima has been extremely thorough as he addresses each of my medical concerns and ensures I have access to the right resources and specialists. The entire staff is very personable and creates a comfortable environment in all interactions. I would highly recommend Dr. Hiroshima at PD to everyone."

"I am extremely happy that I chose Dr. Hiroshima with Peninsula Doctor. The office and staff make it an incredible experience as soon as you walk through the doors. Staff at PD are very nice and personable and more importantly they stay informed and work with me on my health needs, active concerns and Prevention! I actually found Dr. Hiroshima by googling concierge care, not only have I been a patient but my spouse has joined this stellar team. I have also recommended a few people to Dr. Hiroshima and I would continue to do so because they have changed what our medical experience has been like back to a foundation of "caring." In recent years it has been increasingly hard to keep a primary doctor. Being a patient here is worth calling and speaking to a team of people who I can speak directly to every time. Thank you, Peninsula Doctor Team for your careful care of my family."

"Dr. Kroes is one of the most knowledgeable, authentic and compassionate doctors I've had the pleasure of interacting with. He is a brilliant diagnostician and partner for our healthcare needs. He is always there when we need him, calmly and capably helping determine the right course of action. His network is vast, and he always knows which specialists to connect with when necessary. He is very well-respected by the broader medical community. His entire practice is also super responsive and professional, from his business operations partner Sabina to his nurse and medical assistant. I couldn't recommend him and the practice more highly!"

"Dr. Kroes is a wonderful doctor. He has been my primary care physician for over 10 years and I am very grateful for his care. Like a great doctor, he is experienced and extremely knowledgeable. What separates Dr. Kroes from the rest is his compassion and kindness, combined with uncommon intelligence and awareness. He has a relaxed manner and is easily able to make one feel at ease. I highly recommend Dr. Kroes!"

"Dr. Kroes is an amazing doctor I highly recommend. Whether you or a family member have an illness requiring specialized care or are healthy with basic medical needs, he’s the best. I first hired Dr. Kroes for my husband who had severe MS, and was at a critical stage of his illness. I remember at our first meeting how generous he was with his time, taking immediate action to put a plan in place for his care. What followed were many visits, phone calls, emails, discussions with our home nurse, supporting us through hospitalizations, and fighting alongside us for anything we needed (a specialized hospital bed, and home oxygen are just two examples). My husband’s case was very complex with a long list of issues facing us. Dr. Kroes and his staff helped at every step. Dr. Kroes started caring for me and my daughter as well. He readily responds to anything we need, plus truly caring about us. I’m not sure how you could find a better doctor."
