Dr. Sylvia Park is wonderful. Listens and makes adjustments based on the patient stated needs and symptoms. Dr Park is a good listener, kind, thorough, and always asks if the plan sounds okay to the patient before implementing. Some docs take literally 5 minutes with the patient. Dr Park isn't one of those... The virtual visits are handy for those who work M-Fri. They are on time. I work my lunch breaks around the appointment time, and rarely does it interfere with my half hour break... and then only by 5 minutes max. Highly recommend this provider! First visit was in person in Portland, all subsequent ones have been virtual. Come prepared with a list of what you've tried in the past, and why it failed (if you can remember-I couldn't remember everything at my visit, so don't stress if you don't have all your ducks in a row😉) and you'll have a productive first visit and leave with a plan of action to tackle whatever diagnosis you struggle with.

Delinda Mercer, Ph.D, is a wonderful couple's counselor for my husband and I. Dr.Mercer has taught us new healthy ways to communicate and get our needs met as individuals and in our relationship with each other. I, we, recommend her highly. Her skills of expertise is shown with helping couples learn to to communicate without strong emotional feelings so each person can hear what each other are saying. She has been instrumental in helping my husband and myself in a thirty-seven year marriage. Who says you can't teach an old dog new tricks! Lol

I felt very comfortable, was given rights to a say in my treatment (individualized treatment), informed about my medicine and it's side effects and abilities, and signed authorization forms to connect this provider to my others for coordinated treatment. I believe this provider has my best health interests in her decisions. I only like to take what I have to for medications to keep optimal kidney/liver functioning, so I think this provider will be very good for my care. Thank You for your candor and care.

Lifestance has provided me with a positive experience in learning about and maintaining my mental health. All the providers I have worked with have been supportive, informative and professional. I truly believe that Lifestance has helped change my life for the better. I highly recommend Lifestance if you are seeking help and support with mental health, namely managing grief and recovery from trauma and abuse with talk therapy and medication management.

I had only a short wait to get in to see my new therapist. Staff at reception desk provided needed assistance with getting telehealth set-up. Office environment is comfortable and the location is scenic. I found an instant report with my therapist, a very experienced and compassionate emotional guide.Without reservation I heartily recommend LifeStance for both in office and telehealth weekly meetings.

Need to be honest, my teenage son is the patient, not me, but I have had a great relationship with the doctor. He is available when we need to talk to him and is very serious about the confidentiality with my son. We see our doctor through telehealth and my son looks forward to his bimonthly appointments. I would highly recommend them.
