Psychiatric Care in Rancho Cucamonga, California
That Actually Makes Sense.
D&Y Integrated Psychiatry provides adult telehealth psychiatry throughout California, including Rancho Cucamonga. Every appointment ends with a clear diagnosis, a structured treatment plan, and a provider who took the time to get it right.
Thoughtful Psychiatric Care, Available Wherever You Are in California
Working adults in Rancho Cucamonga juggle long commutes along the I-10 and I-15, demanding jobs, and the pressure to keep up with the pace of life in San Bernardino County. Between the traffic, the work stress, and everything waiting at home, it's easy to push aside the anxiety, sleep problems, or low mood that creeps in. When you're busy, those things can linger for months without real attention.
D&Y Integrated Psychiatry brings psychiatric care directly to your home or office through telehealth, so you don't have to add another drive to your day. We accept most major insurance plans, and getting started is simple: book an appointment to talk about what's going on. That conversation helps us figure out whether medication, therapy, or both make sense for you. You deserve care that fits your actual life.

We Were Built to Be the Alternative.
Rancho Cucamonga adults face a significant psychiatry shortage, with wait times at local health systems often stretching months. D&Y's diagnosis-first approach cuts through this bottleneck by delivering expert psychiatric evaluation and treatment planning within days, not quarters. For working professionals and families in the Inland Empire, getting a clear diagnosis and actionable treatment path quickly means you can start feeling better without the frustration of traditional care delays.
Diagnosis First, Always
Every appointment starts with getting the full clinical picture before any prescription is discussed. No guesswork, no rushing to a quick answer.
Unhurried Appointments
Your first evaluation runs 60 to 90 minutes. You will not leave confused about what was decided or why. Clarity is the standard, not the exception.
Conservative Prescribing
The minimum medication necessary for meaningful improvement. Denis does not prescribe first and evaluate second. Never rushed. Never arbitrary.
Military and VA Experience
Denis served 10 years as a U.S. Air Force officer and completed his psychiatric residency at the VA Greater Los Angeles Healthcare System. He understands this population personally, not just clinically.

Telehealth
Denis Grigorov is a board-certified PMHNP with a background spanning 10 years of military service as a commissioned U.S. Air Force officer, emergency nursing in high-acuity hospital settings, and a 12-month psychiatric residency at the VA Greater Los Angeles Healthcare System. That combination produced a provider who is calm under pressure, unusually thorough in diagnosis, and attuned to patients who have been carrying a significant load for a long time.

D&Y is named for Denis and his wife Yesenia. This is not a corporate identifier. It is a declaration that this practice was built on real family values, not a business model. Yesenia is a high school teacher, a reminder that the people Denis serves are working professionals, educators, and community contributors who deserve care that meets them where they are.
